WORKINGMAN’S 10
80 watt, 1x10 combo amplifier with tweeter. A small yet
powerful bass cube, extremely portable. The SWR Sound“to go.”Speaker Complement:(1) Custom Designed 10" SWR driver(1) Custom Designed Piezo tweeter
Power Output: 80 Watts RMS, 100 Watts RMS @ 4 Ohms
(with 8 ohm extension speaker)
Impedance: 8 Ohms (internal)
Dimensions: 16.25" W x 14.5" H x 14" D
Weight: 32 lbs.
TOP PANEL FEATURESINPUT JACKThis jack accepts any standard instrument cable that connects via 1/4" plugs. The Workingman’s 10 Input Jack accomodates
both passive and active instruments. The high input impedance assures perfect compatibility for all active/passive/magnetic
and piezo pick-up systems.
VOLUME CONTROL

Turning the Volume Control clockwise or toward “Max” increases the volume of the Workingman’s 10. Turning it counter-clockwise or toward “Min” decreases the volume. If the Volume Control is in the full counter-clockwise position, no sound will be audible.
Playing your Workingman’s 10 at excessive volume can result in clipping of the power amplifier section. If you hear distortion
through your speakers, decrease the setting of the Volume Control. Clipping will not harm the Workingman’s 10 electronics, but
can cause damage to the internal speaker components and is not recommended.
NOTE: Overdriving the Workingman’s 10 for extended periods of time can activate the amplifier’s thermal protection circuitry,
resulting in temporary loss of output.

If you require more volume than the Workingman’s single 10" speaker can provide, we recommend adding an extension speaker cabinet with an impedance of no less than 8 ohms.
AURAL ENHANCER

The Aural Enhancer was developed to bring out the fundamental low notes of the bass, reduce certain frequencies that can“mask” fundamentals, and enhance the high-end transients. The effect becomes more pronounced as the control is turned up.
The result is a more transparent sound. Listening to a passive bass with the control set all the way down, and then turning it all
the way up, can be likened to listening to the bass suddenly becoming “active.”

TONE CONTROL SECTION
The Workingman’s 10 Tone Control section is a three-band set of level controls centered around the frequencies 80 Hz (bass),
800 Hz (mid range) and 5kHz (treble). Each control can cut or boost its band a maximum of 15dB. Each control has a flat (center click) position that defeats its function.
In this position, the tone controls are inactive.
For each tone control, rotating the knob counter-clockwise from the center “click” position will reduce or cut its designated frequency. Rotating the knob clockwise will boost its designated band or frequency.
2 • WORKINGMAN’S COMBOS OWNER’S MANUALUSING THE TONE CONTROLS

To get the most out of the Tone Controls of your Workingman’s 10, it would be best to first understand how the Aural Enhancer
works, and how it interacts with the Bass, Midrange and Treble controls. Think of it as a variable tone curve, changing with its
position. As you raise the control from “0,” or the fully counterclockwise position, you are elevating the whole range of sound(lows, mids, and highs) at frequency points different than those selected for the individual Tone Controls. This remains true up
to about the “2 o’clock” position, at which point the mids start to drop off. The curves involved here are gentle, as opposed to
the very extreme curves you can create with the Tone Controls. Most significantly, the Aural Enhancer will raise the low end ata point lower than the Bass control itself.
For a typical 4-string bass, the Bass control itself will suffice. For the 5-string player, the Aural Enhancer will help bring out thefundamentals of your instrument (in the 30-60 Hz range). Discretion should be used when doing this without an extension cabinet. True low fundamentals (one of the sonic signatures of all SWR amplifiers) require lots of headroom and air motion. That’s
why we recommend that 5-string players use an extension cabinet to increase the power output of the amplifier and get more
air moving.
BASS CONTROLThe Bass control, as stated above, works in a range that will be useful under most “normal” conditions. Its musical use might
be thought of as a “fatness” control. Leaving the Aural Enhancer in a position lower than 12 o’clock will not boost the extreme
bottom so much as to make indistinct the working of the Bass control. The overall “punch” of your instrument, from your low Estring on up about two octaves (midway up the G-string), will be determined with this control. With passive instruments, this will
be straightforward. With active instruments having bass-boost controls, more exploration will be worthwhile. (Some active tone
circuits have boost-cut controls, while others have straight boost controls).
MID RANGE CONTROLThe Mid Range control operates in a crucial area for most instruments. Many basses, particularly those strung with roundwound strings, can have a very “honky” or nasal sound. Dropping the Mid Range control can go a long way toward smoothingout your tone. We suggest, though, that what sounds best when you’re listening to your tone by yourself may not be whatworks best in a band or on a recording. Sometimes that objectionable quality may be just the right “hair” on your note to still
have an audible presence in the track or on stage.
TREBLE CONTROLThe Treble control operates in a tonal area that extends through and beyond the usual Treble control range. It may be thoughtof as a “transparency” control. Boosting the control will open up the sound of a dull instrument, particularly in conjunction withthe piezo tweeter in the Workingman’s 10. However, this is also the range of string rattle, finger slides, pickup clicks, etc. Again,
we recommend you experiment with the control alone with your instrument while finding your tone, and listen again in a bandcontext, both near to and away from the Workingman’s 10. Qualities such as punch, fatness, presence and bite can be fairly
well spread out. Treble, despite the broad dispersion of the piezo tweeter, is a very directional quality. Spend some time exploring what you hear in this area as you move around.
EFFECTS BLENDThe Effects Blend control mixes the signal coming from your instrument with the sound coming from your effect. With the Blend
control fully counterclockwise, no signal from your effect will be heard. As you turn this control clockwise, more of the effect canbe heard in the overall sound. When the Blend control is fully clockwise, no dry or unaffected signal is heard other than the output
of your effect device.
This type of control and patching arrangement is very effective in reducing noise caused by effects devices and in maintaining
a more natural sound. If your effects device has a similar control, we suggest leaving it set to its maximum effect/minimum dry
signal position and using the Effects Blend control for this function. Please read the “Effects Loop” section for more information.

POWER SWITCH

Pressing the Power Switch to the ON position activates the Workingman’s 10 electronics as indicated by the LED above theswitch.

REAR PANEL FEATURESTO TUNERThe To Tuner send jack allows the user to connect their instrument tuner to the Workingman’s 10 without having to unplug andgo back and forth from amp to tuner to amp. This feature is isolated from the rest of the circuitry and no other controls otherthan your instrument have an effect on it. Being on an isolated sidechain also avoids loading down of the instrument, which cancause a loss in dynamic range.
To use this feature, plug in a shielded patch cord from this jack to the INPUT of your tuning device. Turn the amp on and you’reready to go. If you don’t want to monitor your sound while tuning, turn down the Volume control or position the selector switch
on the back panel to the “headphones only” (middle) position.
EFFECTS LOOPThe Effects Loop is located POST EQ in the signal path. The level appearing at the Send jack is controlled by the Volume control on the front panel. If you are getting too hot a signal to the input of your effect, reduce the level of the Volume control. By
using the Volume and Effects Blend controls, optimum performance should be easily obtainable with any effects device.
The Effects Loop is designed as a “sidechain” (parallel) function similar to those found on mixing consoles. Use of the Effects Loop
should greatly reduce noise generated by effects devices (as compared to in-line effects loops). Additional features of this type ofloop can be found below under “Receive Jack.”
SEND JACK

Run a shielded patch cable from the Send jack to the input of your effects device. This jack may be used as an additional line
level output, in which case its level is determined by the setting of the Volume control.
RECEIVE JACK

Run a shielded patch cable from the output of your effects device to the Receive jack.
One unique feature of the Receive jack is the ability to practice along with pre-recorded music. Insert a sound source into the
Receive jack (make sure it is a mono source). Use the Effects Blend control to mix the level of the recorded music with yourinstrument’s level. The combined signal will be heard through the internal speakers or your headphones. The send jack is not
used.
NOTE: Inserting a plug into the Receive jack activates the Effects Blend control by receiving a “command” through the ground created. Therefore, only a mono (2-conductor) phone plug should be used. If you have a stereo (3-conductor) plug only, tie the ring and thesleeve (ground) together.

If you are not getting any “effect” through the speakers, check the position of the Effects Blend control.
EXTENSION SPEAKER JACKUse an unshielded 2-conductor cable (NOT A GUITAR CORD!) to connect an additional speaker cabinet. Use a high quality,
heavy gauge cable of at least 18 gauge (the lower the gauge, the heavier the cable). The impedance of the speaker should be
8 ohms or greater. If you wish to connect two additional cabinets be sure their combined impedance is not less than 8 ohms
(equivalent to two 16 ohm speaker cabinets in parallel).
RECOMMENDED SPEAKER CABS FROM SWR ARE: Workingman’s 1X10T, Workingman’s 1X15T, Workingman’s
2X10T, Workingman’s 4X10T.

4 • WORKINGMAN’S COMBOS OWNER’S MANUALSTEREO HEADPHONES JACK

By inserting a set of stereo headphones into this jack you will be able to monitor your sound or practice without disturbing
your neighbors. The headphone volume level is adjusted by the Volume control. We suggest you begin with the Volume off (fully
counterclockwise), then slowly bring the volume up to your desired level. If you hear some distortion in your headphones that is
not present with the speakers on, turn down the volume—you are overdriving your headphones and could ruin them.
Any impedance stereo headphones will work. However, optimum impedance is 75 ohms.
THREE WAY SELECTOR SWITCH

The top position, labeled Full Range, activates both the tweeter and the 10" woofer in the WorkingMan’s 10, as well as theextension speaker jack. This position is the most typical setting.
The middle position, labeled Headphones Only, disconnects the signal going to the internal speakers and extension speakerjack. Use this position when listening with heaphones only or for silent tuning (refer to To Tuner section). The Headphones jack isalways active regardless of the switch’s position.
The bottom position, labeled Horn Off, disconnects the tweeter located in the upper right hand corner of the speaker cabinet. It will not affect the 10" woofer, headphones or any extension cabinet. If you prefer a “darker” sound or are getting a lot offret buzz, clicks, or pick or finger noise, you may want to use this position.
BALANCED DIRECT RECORD OUT

The Balanced XLR output is a true balanced output. No front panel controls affect its signal. The tone and output level are controlled only by the instrument plugged into one of the input jacks. To use this feature, run an XLR (Cannon) cable from theBalanced D.I. to the input of a tape machine, mixing console, etc. This output is also suitable for sending a signal to a housemixer in live situations.
Wiring for the XLR connector is as follows: Pin 1 = ground, Pin 2 = +, Pin 3 = –. (American standard)
NOTE: Do not apply phantom power (48V supply) to this output. Doing so may damage the internal circuitry.
A/C LINE FUSE
The line fuse can open (blow) due to power surges or high powerline transients. This fuse will also open in the event of an electronics failure inside your amplifier. Correct size and rating of the Line (Mains) fuse: 3AG, 2 amp slo-blow for 120V operation(North America), and 1 amp slo-blo for 240V operation.
A/C LINE CORD RECEPTACLE
Accepts a standard A/C power cable (supplied with the Workingman’s 10 in the United States), used with almost all current musical, professional and household electronic devices. If it becomes misplaced, replacement will be easy at almost any computer,electronics or pro audio store.
NOTE: The rating for this cable is 3-conductor, 10 amperes. This is a rating of the current capacity of the cable, designated for higher power-drawing devices like amplifiers. If replacement is necessary, or if you wish to buy a longer cable,
look for the rating on the cable and be sure it is at least 10 amps.

FRONT PANEL FEATURESBALANCED DIRECT RECORD OUT
The Balanced XLR output is a true balanced output. No front panel controls affect its signal. The tone and output level are controlled only by the instrument plugged into one of the input jacks. To use this feature, run an XLR (Cannon) cable from theBalanced D.I. to the input of a tape machine, mixing console, etc. This output is also suitable for sending a signal to a housemixer in live situations.

TO TUNERThe To Tuner send jack allows the user to connect their instrument tuner to the Workingman’s 12 without having to unplug andgo back and forth from amp to tuner to amp. Like the Balanced D.I. output, this feature is isolated from the rest of the circuitry
and no other controls other than your instrument have an affect on this feature. Being on an isolated sidechain also avoids
loading down of the instrument, which can cause a loss in dynamic range.
To use this feature, plug in a shielded patch cord from this jack to the INPUT of your tuning device. Turn the amp on and you're
ready to go. If you don’t want to monitor your sound while tuning, turn down the Master Volume control or position the selector
switch on the back panel to the “headphones” (middle) position.
INPUT JACKSTwo separate and independent input jacks are provided so that the best signal-to-noise ratio can be obtained without overloading the preamp section. The Passive input has over twice the gain than that of the Active input. Both inputs can be used simultaneously without affecting the volume or tone of the other. One use of these inputs would be to plug your bass into the
Passive input and practice along with a drum machine by plugging it into the Active input. A more detailed explanation of these
inputs follows.
Passive Input
This input can and should be used if your instrument has passive electronics (no built-in preamp). Some pickups employ batteries for operation and will work perfectly using this input. Technically speaking, this input should be used if your instrument has an
output voltage of 1 volt RMS or LESS. Consult the owner’s manual that came with your instrument or ask the manufacturer if you
are unsure.
NOTE: Generally speaking, you should try the Passive input jack first. If you hear a small amount of distortion and thePreamp Clip LED is not activated, try using the Active input jack. Some passive pickups DO distort. Because of the hi-fi
nature of all SWR products, even the smallest amount of distortion originating at the source (instrument) may be heard.
WORKINGMAN’S COMBOS OWNER’S MANUAL • 7

Active Input
The Active input jack should be used with instruments having a built-in (on-board) preamp that will produce signals over 1 volt
RMS. Some really “hot” pickups installed in your instrument may find the Active input more compatible. The best judge is yourown ears.
NOTE: Using the Active input with passive basses may result in a loss of high-end transients. Players who roll off theirhigh-end starting at around 2k to 3kHz may find this input more to their liking.
If your hear some distortion from your active bass and are using the Active input jack, check your battery. Also, make sure thePreamp Clip LED is not lighting.
PREAMP CLIP LED
The Preamp Clip LED will light whenever the Preamp, Tone section or output buffer reach clipping (that is, run out of headroom). In the event the Preamp Clip LED lights, turn down the Gain control. Since the Preamp Clip also monitors the Tone section, boosting any one of the tone controls can cause the LED to activate. Again, turn down the Gain control if this happens.
NOTE: Constant clipping of the preamp will not harm the electronics in your Workingman’s 12. However, damage canoccur to speakers due to near-DC content present in a clipped waveform.
GAIN CONTROLThe Gain control adjusts the volume of the preamp section. After the Tone controls, Aural Enhancer and any effects you may
be using have been set to your liking, the Gain control should be set to where the Preamp Clip LED barely flashes upon hitting
your loudest note. After setting the Gain, use the Master Volume to set the desired volume level. Using these controls in thismanner assures the maximum signal-to-noise ratio with no distortion caused by the preamp circuits clipping. Since the Gain
control is similar to a “pad,” a small amount of signal will get through with the Gain control turned all the way down. The Gainalso adjusts the level sent to the Effects send jack. If your effect is being overdriven, turn down the Gain control.
TONE CONTROL SECTION
The Workingman’s 12 Tone Control section is a three-band set of level controls centered around the frequencies 80 Hz (Bass),
800 Hz (Mid Range) and 5kHz (Treble). Each control can cut or boost its band a maximum of 15dB. Each control has a flat(center “click”) position that defeats its function. In this position, the tone controls are inactive.
For each tone control, rotating the knob counter-clockwise from the center “click” position will cut (reduce) its designated frequency. Rotating the knob clockwise will boost its designated band or frequency.
Using the Tone Controls
To get the most out of the Tone Controls of your Workingman’s 12, it would be best to first understand how the Aural Enhancer
works, and how it interacts with the Bass, Mid Range and Treble controls. Think of it as a variable tone curve, changing with its

MASTER VOLUME
The Master Volume control adjusts the signal level going to the power amplifier. It DOES NOT control the output of the effects
send jack or Balanced Direct Record XLR output. It DOES affect the output of the internal speakers, headphones, and extension speaker jack. Losses caused by effects units can be recovered by increasing the Master Volume.
NOTE: If you need more volume than the Workingman’s single 12" can provide, add an extension speaker cabinet. The
extension cabinet should have an impedance of 8 ohms or greater.

WORKINGMAN’S COMBOS OWNER’S MANUAL • 9

LIMITER CIRCUIT
The Workingman’s 12 Limiter Circuit is a soft knee type limiter that prevents distortion of attack transients or peaks. The
Limiter can be used as an effect and is also helpful in preventing speaker damage. The circuit is located after (post) the master volume and before (pre) the power amplifier; it is driven by the Master Volume control. Its threshold (starting point) is presetby the factory so that the user can get maximum overall apparent volume without unduly overdriving the power amplifier.
LIMITER LED
The Limiter LED lights when your signal has reached the Limiter threshold, letting you know that the Limiter circuit has been
activated.
NOTE: No harm is being done to your amplifier when this LED lights or stays lit.
POWER SWITCH
Pressing the Power Switch to the ON position activates the Workingman's electronics as indicated by the red LED above theswitch.

FRONT PANEL FEATURESBALANCED DIRECT RECORD OUT
The Balanced XLR output is a true balanced output. No front panel controls
affect its signal. The tone and output level are controlled only by the instrument
plugged into one of the input jacks. To use this feature, run an XLR (Cannon) cable from the Balanced D.I. to the input of a tapemachine, mixing console, etc. This output is also suitable for sending a signal to a house mixer in live situations.
Wiring for the XLR connector is as follows: Pin 1 = ground, Pin 2 = +, Pin 3 = –. (American standard)
TO TUNERThe To Tuner send jack allows the user to connect their instrument tuner to the Workingman’s 15 without having to unplug andgo back and forth from amp to tuner to amp. Like the Balanced D.I. output, this feature is isolated from the rest of the circuitry
and no other controls other than your instrument have an affect on it. Being on a sidechain (isolated) also avoids loading downof the instrument, which can cause a loss in dynamic range.
To use this feature, plug in a shielded patch cord from this jack to the INPUT of your tuning device. Turn the amp on and you’reready to go. If you don’t want to monitor your sound while tuning, turn down the Master Volume control or position the selector
switch on the front panel to the “headphones” (middle) position.
INPUT JACKSTwo separate and independent input jacks are provided so that the best signal-to-noise ratio can be obtained without overloading the preamp section. The Passive input has over twice the gain than that of the Active input. Both inputs can be used simultaneously without affecting the volume or tone of the other. One use of these inputs would be to plug your bass into the
Passive input and practice along with a drum machine by plugging it into the Active input. A more detailed explanation of these
inputs follows.
Passive Input
This input can and should be used if your instrument has passive electronics (no built-in preamp). Technically speaking, this
input should be used if your instrument has an output voltage of 1 volt RMS or LESS. Consult the owner’s manual that camewith your instrument or ask the manufacturer if you are unsure.
NOTE: Generally speaking, you should try the Passive input jack first. If you hear a small amount of distortion and thePreamp Clip LED is not activated, try using the Active input jack. And please note, some passive pickups DO distort.
Because of the hi-fi nature of all SWR products, even the smallest amount of distortion originating at the source (instrument) may be heard.
14 • WORKINGMAN’S COMBOS OWNER’S MANUAL

Active Input
The Active input jack should be used with instruments having a built-in (on-board) preamp that will produce signals over 1 volt
RMS. Some really “hot” pickups installed in your instrument may find the Active input more compatible. The best judge is yourown ears.
NOTE: Using the Active input with passive basses may result in a loss of high-end transients. Players who roll off theirhigh-end starting at around 2kto 3kHz may find this input more to their liking.
If your hear some distortion from your active bass and are using the Active input jack, check your battery. Also, make sure thePreamp Clip LED is not lighting.
PREAMP CLIP LED
The Preamp Clip LED will light whenever the Preamp, Tone section or output buffer reach clipping (that is, run out of headroom). In the event the Preamp clip indicator lights, turn down the Gain control. Since the Preamp Clip also monitors the Tone
section, boosting any one of the tone controls can cause the LED to activate. Again, turn down the Gain control if this happens.
NOTE: Constant clipping of the preamp will not harm the electronics in your Workingman’s 15. However, damage canoccur to speakers due to near-DC content present in a clipped waveform.
GAIN CONTROLThe gain control adjusts the volume of the preamp section. After the Tone controls, Aural Enhancer and any effects you may beusing have been set to your liking, the Gain control should be set to where the Preamp Clip LED barely flashes upon hitting
your loudest note. After setting the Gain, use the Master Volume to set the desired volume level. Using these controls in thismanner assures the maximum signal-to-noise ratio with no distortion caused by the preamp circuits clipping. Since the Gain
control is similar to a “pad,” a small amount of signal will get through with the Gain control turned all the way down. The Gainalso adjusts the level sent to the Effects send jack. If your effect is being overdriven, turn down the Gain control.
TONE CONTROL SECTION
The Workingman’s 15 Tone Control section is a three-band set of level controls. The Bass and Treble controls are centeredaround the frequencies 80 Hz (Bass), and 5kHz (Treble). The Mid Range controls comprise a level control and a frequency control knob.
Each control (except Mid Frequency) can cut or boost its band a maximum of 15dB. Each control has a flat (“center click”) position that defeats its function. In this position, the tone controls are inactive.
For each tone control (except Mid Frequency), rotating the knob counter-clockwise from the center click position will reduce or
cut its designated frequency. Rotating the knob clockwise will boost its designated band or frequency.
Using the Tone Controls
To get the most out of the Tone Controls of your Workingman’s 15, it would be best to first understand how the Aural Enhancer
works, and how it interacts with the bass, mid range and treble controls. Think of it as a variable tone curve, changing with its
position. As you raise the control from its “0,” or fully counterclockwise position, you are elevating the whole range of sound (lows,
mids, and highs) at frequency points different than those selected for the individual Tone Controls. This remains true up to about
the “2 o’clock” position, at which point the mids start to drop off. The curves involved here are gentle, as opposed to the very
extreme curves you can create with the Tone Controls.
Most significantly, the Aural Enhancer will raise the low end at a point lower than the Bass control itself. For a typical 4-string
bass, the Bass control itself will suffice. For the 5-string player, the Aural Enhancer will help bring out the fundamentals of yourinstrument, in the 30-60 Hz range. Discretion should be used when doing this without an extension cabinet. True low fundamentals (one of the sonic signatures of all SWR amplifiers) require lots of headroom and air motion. It is for this reason that we recommend that 5-string players use an extension cabinet to increase the power output of the amplifier and get more air moving.

WORKINGMAN’S COMBOS OWNER’S MANUAL • 15

Bass Control
The Bass control, as stated above, works in a range that will be useful under most “normal” conditions. Its musical use might
be thought of as a “fatness” control. Leaving the Aural Enhancer in a position lower than 12 o’clock will not boost the extreme
bottom so much as to make indistinct the effect of the Bass control. The overall “punch” of your instrument, from your low Estring on up about two octaves (midway up the G- string), will be determined with this control. With passive instruments, this will
be straightforward. With active instruments having bass-boost controls more exploration will be worthwhile. (Some active tone
circuits have boost/cut controls, while others have straight boost controls).
Mid Range Controls
The Mid Range controls operate in a crucial area for most instruments. The Mid Level control cuts or boosts the frequency,
which is set by the Mid Frequency control. Starting at mid-position, turning the Mid Level control counter clockwise cuts the frequency determined by the Mid Frequency control. Turning the Mid Level control clockwise boosts the frequency determined by
the Mid Frequency control.
Many basses, particularly those strung with roundwound strings, can have a very “honky” or nasal sound. Adjustments made with
the Mid Range controls can go a long way toward smoothing out your tone. We suggest, though, that what sounds best whenyour listening to your tone by yourself may not be what works best in a band or recording. Sometimes that objectionable quality
may be just the right “hair” on your note to still have an audible presence in the track or on stage.
NOTE: When the level control is set at the “center click” (mid) position, turning the frequency control will have no effecton the sound.
To find the mid range area you are looking for:
1. Adjust the Mid Level control to the full boost or cut position.
2. Rotate the Mid Frequency control until the desired area you wish to cut or boost is found.
3. Adjust the Mid Level control to the desired amount of cut or boost for the frequency you have selected.
The Mid Frequency control sets the area that is to be cut or boosted by the Mid Level function. If the Level control is set at midposition, turning the Frequency knob will have NO affect.
Some hints: If you need to “cut through” the band a little more, try boosting 200 to 400 Hz. If you like a more transparent
sound, try cutting at 800 Hz. The midrange area is especially useful in controlling fretless basses and their inherent qualities.
Treble Control
The Treble control operates in a tonal area that extends through and beyond the usual Treble control range. It may be thoughtof as a “transparency” control. Boosting the control will open up the sound of a dull instrument, particularly in conjunction withthe piezo tweeter in the Workingman’s 15. However, this is also the range of string rattle, finger slides, pickup clicks, etc. Again,
we recommend you experiment with the control alone with your instrument while finding your tone, and listen again in a bandcontext, both near to and away from the Workingman’s 15. Qualities such as punch, fatness, presence and bite can be fairly
well spread out. Treble, despite the broad dispersion of the piezo tweeter, is a very directional quality. Spend some time exploring what you can hear in this area as you move around.
Transparency Control
The Transparency control is a shelving type tone control that cuts or boosts the high frequencies a full octave above the treble
function. Shelving point for this control is about 5 kHz.
AURAL ENHANCER
The Aural Enhancer was developed to bring out the fundamental low notes of the bass, reduce certain frequencies that can“mask” fundamentals, and enhance the high-end transients. The effect becomes more pronounced as the control is turned up.
The result is a more transparent sound. Listening to a passive bass with the control set all the way down, and then turning it all
the way up, can be likened to listening to the bass suddenly become “active.”
16 • WORKINGMAN’S COMBOS OWNER’S MANUALEFFECTS BLEND CONTROLThe Effects Blend control mixes the signal coming from your instrument with the sound coming from your effect. With the
Blend control fully counter-clockwise, no signal from your effect will be heard. As you turn this control clockwise, more of theeffect can be heard in the overall sound. When the Blend control is fully clockwise, no dry or unaffected signal is heard other thanthe output of the effect device.
This type of control and patching arrangement is very effective in reducing noise caused by effects devices and in maintaining
a more natural sound. If your effects device has a similar control, we suggest leaving it set to its maximum effect/minimum dry
signal position and using the Effects Blend control for this function. Please read the “Effects Loop” section for more information.
LIMITER DEFEAT SWITCH
Pulling out the Effects Blend knob until a click is felt deactivates the Internal limiter circuit. Pushing the control back in, activatesthe circuit.
MASTER VOLUME
The Master Volume adjusts the signal level going to the power amplifier. It DOES NOT control the output of the effects send
jack or Balanced Direct Record XLR output. It DOES affect the output of the internal speakers, headphones, and extension
speaker jack. Losses caused by effects units can be recovered by increasing the Master Volume.
NOTE: If you need more volume than the Workingman’s single 15” can provide, add an extension speaker cabinet. The
extension cabinet should have an impedance of no less than 8 ohms.
LIMITER CIRCUIT
The Workingman’s 15 Limiter Circuit is a soft knee type limiter that prevents distortion of attack transients or peaks. The
Limiter can be used as an effect and is also helpful in preventing speaker damage. The circuit is located after (post) the master volume and before (pre) the power amplifier; it is driven by the Master Volume Control. Its threshold (starting point) is preset by the factory so that the user can get maximum overall apparent volume without unduly overdriving the power amplifier.
LIMITER LED
The Limiter LED lights when your signal has reached the Limiter threshold, letting you know that the Limiter circuit has been
activated.
NOTE: No harm is being done to your amplifier when this LED lights or stays lit.
THREE WAY SELECTOR SWITCH
The top position, labeled Full Range, activates both the tweeter and the 15" woofer in the Workingman’s 15, as well as theextension speaker jack. This position is the most typical setting.
The middle position, labeled Headphones Only, disconnects the signal going to the internal speakers and extension speakerjack. Use this position when listening with heaphones only or for silent tuning (refer to To Tuner section). The Headphones jack isalways active regardless of the switch’s position.
The bottom position, labeled Horn Off, disconnects the tweeter located in the upper right hand corner of the speaker cabinet. It will not affect the 15" woofer, headphones or any extension cabinet. If you prefer a “darker” sound or are getting a lot offret buzz, clicks, or pick or finger noise, you may want to use this position.

WORKINGMAN’S COMBOS OWNER’S MANUAL • 17

STEREO HEADPHONES JACK
By inserting a set of stereo headphones into this jack you will be able to monitor your sound or practice without disturbing yourneighbors. The headphone volume level is adjusted by the Master Volume. We suggest you begin with the Master Volume off (fully
counter-clockwise), then slowly bring up the volume to the desired level. If you hear some distortion in your headphones that is notpresent with the speakers on, turn down the volume—you are probably overdriving your heaphones and could ruin them.
Any impedance headphones will work. However, optimum impedance is 75 ohms.
POWER SWITCH
Pressing the Power Switch to the ON position activates the Workingman’s 15 electronics as indicated by the LED above theswitch.

REAR PANEL FEATURESEFFECTS LOOPThe Effects Loop is located POST EQ and PRE Master Volume in the signal path. The level appearing at the Send jack is controlled by the Gain control on the front panel. If you are getting too hot a signal to the input of your effect, reduce the level ofthe Gain control and raise the level of your Master Volume control to retain similar overall volume levels. By using the Gain,
Master Volume and Effects Blend controls, optimum performance should be easily obtainable with any effects device.
The Effects Loop is designed as a “sidechain” (parallel) function similar to those found on mixing consoles. Use of the Effects
Loop should greatly reduce noise generated by effects devices (as compared to in-line effects loops). Additional features ofthis type of loop can be found below under the “Receive Jack” section.
Send JackRun a shielded patch cable from the Send jack to the input of your effects device. This jack may be used as an additional line
level output, in which case its level is determined by the setting of the Gain control.
Receive JackRun a shielded patch cable from the output of your effects device to the Receive jack.
One unique feature of the Receive jack is the ability to practice along with pre-recorded music. Insert a sound source into the
Receive jack (make sure it is a mono source). Use the Effects Blend control to mix the level of the recorded music with yourinstrument’s level. The combined signal will be heard through the internal speakers or your headphones. The send jack is not
used.
NOTE: Inserting a plug into the Receive jack activates the Effects Blend control by receiving a “command” through theground created. Therefore, only a mono (2-conductor) phone plug should be used. If you have a stereo (3-conductor) plug
only, tie the ring and the sleeve (ground) together.
If you are not getting any “effect” through the speakers, check the position of the Effects Blend control.
EXTENSION SPEAKER JACKUse an unshielded 2-conductor cable (NOT A GUITAR CORD!) to connect an additional speaker cabinet. Use a high quality,
heavy gauge cable of at least 18 gauge (the lower the gauge, the heavier the cable). The impedance of the speaker should be
8 Ohms or greater. If you wish to connect two additional cabinets be sure their combined load impedance is not less than 8ohms (equivalent to two 16 ohms speaker cabinets in parallel).
Recommended speaker cabs from SWR are: Workingman’s 2X10T, Workingman’s 4X10T, Workingman’s
1X15T, Goliath III and Big Ben.

18 • WORKINGMAN’S COMBOS OWNER’S MANUALA/C LINE FUSE
The line fuse can open (blow) due to power surges or high powerline transients. This fuse will also open in the event of an electronics failure inside your amplifier. Correct size and rating of the Line (Mains) fuse: 3AG, 4 amp slo-blow for 120V operation(North America), and 2 amp slo-blo for 240V operation.
A/C LINE CORD RECEPTACLE
Accepts a standard A/C power cable (supplied with the Workingman’s 15 in the United States), used with almost all current
musical, professional and household electronic devices. If it becomes misplaced, replacement will be easy at almost any computer, electronics, or pro audio store.
NOTE: The rating for this cable is 3-conductor, 10 amperes. This is a rating of the current capacity of the cable, designated for higher power-drawing devices like amplifiers. If replacement is necessary, or if you wish to buy a longer cable,
look for the rating on the cable and be sure it is at least 10 amps.
