2 • BASS 750 USER GUIDEFRONT PANEL FEATURESINPUT JACKS
Both input jacks accept a standard 1/4" phone plug and both inputs can be used at the same time. Since thetwo inputs are totally independent, no loss in volume or tone will occur if two instruments are used simultaneously. Please keep in mind, however, that the Active/Passive input has five times more gain than the Active
input.
PASSIVE/ACTIVE INPUT
A “passive” instrument has no built in preamp and does not use a battery. On the other hand, an “active”
bass utilizes a battery operated preamp, either for gain, tone controls, or both. Although labeled “Passive,”
the Passive input jack on your Bass 750 will work with all instruments having a maximum output of less than
1 volt RMS.
Generally speaking, try the Passive input jack first. If you hear a small amount of distortion and the preamp
clip LED is not activated, try using the Active input jack.
Note: If you would like to overdrive the first TUBE stage, this can be accomplished by using an external
preamp between your instrument and the Passive input. To obtain optimum sound when trying this,make sure the preamp clip LED is not activated. If this occurs, turn down your Gain control. The firstpreamp tube stage is NOT monitored by the preamp clip circuit for this reason.
ACTIVE INPUTThe Active input jack should be used with instruments having a built-in (on board) preamp that will produce
signals over 1 volt RMS. Basses with really “hot” pickups may find the Active input more compatible. If you’reusing a KEYBOARD or BASS PEDAL, etc. with the Bass 750, we have found the best choice to be the Active
input.
Note: Using the Active input with a passive instrument may result in a loss of high end transients.
Players who roll off their high end frequencies starting at about 2kHz or who prefer a “darker” soundmay find this input more to their liking.
If you hear some distortion with your active bass and are using the Active input jack, check your instrument’s
battery. Also, make sure that the preamp clip LED is not lit. Following these instructions can save you and aservice technician a lot of aggravation.
HEADPHONE JACK (STEREO ONLY)
By inserting a set of stereo headphones into this jack you can monitor your sound or practice without disturbing your neighbors. 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 not present with the speakers on, turn down the volume.
You are probably overdriving your headphones and could damage them (not to mention your ears).
Note: Any impedance headphones will work. However, optimum impedance is 75 ohms.
GAIN CONTROLThe Gain control adjusts the volume of the preamp section. After the tone controls and limiter are set to yourliking, the Gain control should be set to where the Preamp Clip LED barely flashes upon striking your loudest
note. Then adjust the Master Volume to the desired volume level. Utilizing these controls in this mannerassures the user of maximum signal to noise ratio with no distortion caused by the preamp circuits “clipping.”
PREAMP CLIP LED
The Preamp Clip LED will light if any portion of the preamplifier reaches clipping or runs out of headroom. Thiscan be caused by the Gain Control being set too high or if any of the tone controls are set in a high boost
position. To correct this condition, turn down one of the previously mentioned controls.
Note: The Preamp Clip LED indicates that at some point the preamplifier is clipping. No harm is being
done to your amplifier but, clipping of the power amplifier can cause damage to your loudspeakers andis not recommended.

AURAL ENHANCER
SWR’s Aural Enhancer control was developed to bring out the fundamental low notes of the bass guitar,
reduce certain frequencies that help mask the fundamentals, and enhance the high end transients. The resulting frequency response is similar to that used for recording the bass in the studio. This effect becomes moreradical as the control is turned to maximum. The result is a more “transparent” sound and is especially noticeable when slapping/thumb-style on the bass guitar.
Basically, the Aural Enhancer can be described as a tone shaping control, as it is a passive R/C network thatalters the frequency response throughout the bass spectrum. This pre-shaping is “blended” into the original
signal via the Aural Enhancer control. Exact frequencies affected are dependent on the characteristics of the
instrument used.

ACTIVE TONE CONTROL SECTIONBASS CONTROLThe Bass control adjusts the level of the lower or bass frequencies. Starting at mid-center click-position, turning the control counter-clockwise cuts the bass response; turning the control clockwise boosts the bass
response.
PULL TURBO FUNCTION
Pulling the bass control to the out position widens the bandwidth of the bass control to include frequencies
down to 30Hz (low B on a five string bass). Since some of these notes can be felt more than heard, it is especially important to keep an eye on the preamp clip LED. Constant clipping of these frequencies can diminish
the life of the speakers or cause them to fail.
MID RANGE SECTION
Level Control
The Level control cuts or boosts the frequency set by the Frequency control. Starting at mid-position, turning
the Level control counter clockwise cuts the desired tone. Turning the Level control clockwise boosts thedesired tone. When the level control set at mid (center click) position, turning the frequency control will haveno affect on the sound.
To find the midrange area you’re looking for:
1. Adjust the Level control to the full boost or cut position.
2. Rotate the Frequency control until the desired area you wish to cut or boost is found.
3. Adjust the Level control to the desired amount of cut or boost
Frequency Control
The Frequency control sets the area that is to be cut or boosted by the Level Control. If the Level control is set
at mid-position, turning the Frequency knob will have NO affect.
Note: If you need to “cut through” the band a little more, try boosting 200 to 400Hz. If you like a moretransparent sound, try cutting at 800Hz. The midrange area is especially useful in controlling fretlessbasses and their inherent qualities.
TREBLE CONTROLThe Treble control is a shelving type tone control that cuts or boosts the high notes and their octaves. Startingfrom mid position, turning the control counter-clockwise cuts the highs while turning the control clockwise
boosts the treble region.
PULL TRANSPARENCY FUNCTION
In the normal (in) position, the shelving point of the treble control is approximately 2kHz. By pulling the knob
outward, the shelving point is changed to 4kHz.

4 • BASS 750 USER GUIDEEFFECTS BLENDThis control blends the signal sent from your bass with that coming from your effects unit. With the Effects
Blend control fully counter-clockwise, no signal from your effects will be heard (“dry”). As you turn this control
clockwise, more of the effect can be heard in the overall sound. When the Blend control is fully clockwise(“wet”), no true or unaffected signal is heard other than what your effects unit provides. If your effects unit
has a similar control, adjust it to the fully “wet” position. This will avoid any possible phasing problems.
The Blend circuit is similar to that used on recording consoles with the effects loop on a “side chain” to thenormal circuit. Unless the control is set to the full “wet” position, you will always get the full sound of yourinstrument AND get the diversity an effects unit offers. This circuit is also effective in reducing noise generated by effects units because it is located after the gain stages in the preamp.
The Effects Blend functions only when the effects loop is being used. It is activated when a 1/4" phone plugis inserted into the Effects Receive jack. See the “Effects Loop” section for more information.
LIMITER CONTROLThis Limiter circuit is located after (post) the Master Volume and before (pre) the power amplifier. Therefore, theLimiter is driven by the Master Volume. Its threshold (or starting point) is set by the Limiter control and can beused to achieve maximum overall apparent volume without unduly overdriving the power amplifier or internal
speakers. Turning the Limiter control clockwise (toward “max”) increases the effect of the Limiter circuit.
LIMITER ACTIVE LED
When the threshold of the Limiter circuit is reached, the green Limiter Active LED will light. This LED will beinactive when the Limiter is set to the “off” position or when playing at lower levels.
MASTER VOLUME
The Master Volume adjusts the level being sent to the power amplifier section of the Bass 750 and controls
the overall volume of the unit. It DOES NOT affect the level of the record XLR output in the “line” position.
Losses caused by effects units can be recovered by increasing the Master Volume.
SPEAKER ON/OFF SWITCH
Moving the Speaker On/Off Switch to the “On” position allows the signal from the amplifier to be heard
through any speaker enclosure(s) connected to the Bass 750’s output section. Moving the Speaker On/Off
Switch to the “OFF” position disables the Bass 750’s output section. This feature allows the user to:
1. Use the XLR Output without using the internal speakers. This is especially useful in recording when
you are not miking the speakers and only a direct signal is required.
2. Tune up without interfering with other band members while using the Tuner Send feature.
Note: If you do not hear any sound when you plug in and your system is properly connected, check theposition of this switch!
POWER ON/OFF SWITCH
Moving the Power Switch to the “On” position will turn on the amplifier as indicated by the Power LED lighting(directly above the switch).

REAR PANEL FEATURESAC OR MAINS FUSE
This fuse is provided to protect the internal electronics against power surges, etc. It also protects the unit
against itself should one of the internal components fail. If this fuse should open, replace it with the same
type of fuse and rating.
Note: Do note defeat the purpose of this feature by using a fuse of a higher value. It could damage theunit and will void your warranty!

BASS 750 USER GUIDE • 5

Proper size of the AC fuse for all countries is 3AG. Proper rating of the fuse is as follows:
Japan: 8 amp slo-blo
United States: 8 amp slo-blo
Europe (240V): 4 amp slo-blo
AC CORD RECEPTACLE
Accepts a standard AC power cable (supplied with the Bass 750), used with almost all current musical, professional and household electronic devices. If you misplace your AC power cable, a replacement can be found atalmost any computer. electronics, or pro audio store.
Note: The rating for this cable is 3 conductor, 10 amperes MINIMUM. 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. Make
sure the AC cord is plugged in all the way in both the amp and the wall socket. If your cord ever
becomes frayed or split, replace it immediately.
EFFECTS LOOPThe Effects Loop should accept any effect such as a chorus, flanger, etc. It is designed as a “side chain”
function and works exactly like that of studio consoles. Some effects units have an input level adjustment
switch. Whenever possible, set it at 0 dB. If that’s not an option, +4 dB is fine. The level going to your effectis controlled by the Gain control on the front panel of the Bass 750.
Use of the Effects Loop should greatly reduce the noise generated by effects units (as compared to using theeffect between your instrument and the input jack). This is because the loop is after the preamp gain stages.
Note: The effects loop must be used in conjunction with the Effects Blend control on the front panel.
When that control is in the “dry” position, no effects will be heard.
All patch cords used with the Effects Loop should be as short as possible and should be routed as directly as
possible. Running patch cables over the top of the Bass 750 (as with any amplifier) can induce hum in thecables.
SEND JACK
Run a shielded patch cable from the Bass 750’s “Send” jack to the INPUT of your effects unit. Output impedance of the send jack is 100 ohms. This jack can be used as a line level output to connect a slave poweramp, such as SWR’s Power 750. It may also be used as an unbalanced record out.
RECEIVE JACK
Run a shielded patch cord from the Bass 750’s “Receive” jack to the OUTPUT jack of your effects unit. A
unique feature of the receive jack is that you can practice along with pre-recorded music. To accomplish this,insert a tape recorder or other sound source into the “Receive” jack (make sure it is a MONO source). Using
the Effects Blend control, adjust the level of recorded music from the Receive to the “live” sound of yourinstrument. The mixed sound will be heard through your speakers. This is an excellent way to practice alongwith drum machines. Input impedance of the Receive jack is 27kohms minimum.
Note: Inserting a plug into the “Receive” jack activates the Effects Blend control. The control receives thiscommand through the ground created by the phone plug making contact with the jack. The plug must be amono plug (tip and ground). If you have a stereo plug only, tie the ring and the ground together.
PREAMP OUT JACKThe Preamp Out jack is a post-EQ output that allows a signal to be run to an external power amp (such as thePower 750) or recording device.
SPEAKER FUSE
The speaker fuse is provided to protect your speakers in the unlikely event of a power amp failure or to protect
your power amplifier from incorrect speaker impedances or connections. Size and rating of the fuse is 10 amp,
fast blow. Do not defeat the purpose of this feature by using a higher rated fuse as it could void your warranty
and further damage your amp.

6 • BASS 750 USER GUIDEThe fuse can open as a result of a fault in the speaker cable, the speakers themselves, or the power amp being
sent well into clipping. With this in mind, we recommend keeping spare fuses with the amplifier at all times.
SPEAKER JACKS
Two 1/4" phone jacks (wired in parallel) and two Speakon® connectors (wired in parallel) are provided for
hooking up your speaker system. The minimum load (or impedance) the Bass 750 is designed to drive is 2.67
ohms (the equivalent of one 8 ohm cab and one 4 ohm cab connected in parallel).
It should be noted that the Bass 750’s preamp section can be run without speakers attached to the speakerjacks. (See “Speaker Off/On Switch” under “Front Panel Features.”) This is helpful when using the amplifier
for recording purposes (via the XLR output) and speakers are not required.
Note: The frequency response of the Bass 750 is far greater than usually found in musical instrument
amplifiers (10Hz to 40kHz). This was engineered in order to give the bass player the same punch andclarity on stage as found in the studio or concert P.A. systems. Therefore, it is doubly important that you
be aware of the impedance and power rating of the speakers that you intend to use and that they arecompatible with the Bass 750. Speakers that have been overdriven are easy to detect and are not covered under warranty.
SPEAKER CABLE
Speaker cable should be made of 18-gauge, or heavier, wire. (The thicker the wire, the lower the gauge, so 18gauge is heavier than 20-gauge and so on.) Do not use instrument cables to hook up your speakers. This canresult in intermittent power loss, cause your power amp to oscillate and damage itself and/or your speakers,
and render the cables useless for any purpose.
To connect the Bass 750 to your speakers via the Speakon output jacks, a Neutrik Speakon cable is required.
These cables are NOT supplied with the Bass 750, but are available from your local music retailer or directlyfrom the SWR Service Department.
XLR PADThe XLR Pad control adjusts the level of the Balanced XLR Output. Rotating the control clockwise raises thelevel at this output.
GROUND LIFT
The XLR Pad has a built-in Ground Lift for the Balanced out. Pulling the knob outward lifts the ground (pin 1).
If a persistent hum exists after trying both positions of the ground lift, there is probably a mis-wire or bad
ground in the feed lines to the board or console or a dirty or miswired A/C socket. SWR recommends the purchase of an AC wall socket tester which can identify proper wiring (available at most hardware stores). These
inexpensive devices are a simple way to protect you and your equipment from faulty electrical systems.
LINE/DIRECT SWITCH
The Line/Direct switch gives the user the option of either a line signal (preamp out) or direct signal from the
instrument. The signal appearing at the XLR out is slightly “hotter” than normal D.I.’s. You may want to informthe engineer of this.
To use the Line/Direct function, position the knob in the desired location. Make sure the switch is all the way
to the left or right to avoid intermittants.
Note: Turn-off transients appear at the record outs when the amplifier is shut down. It is recommended
that equipment being used in conjunction with the record out be turned down, off, or disconnected
BEFORE the Bass 750 is turned off.
BALANCED XLR OUT
The Balanced XLR out is a true electronically balanced record out. The signal appearing at the XLR out is governed by the position of the XLR Pad. In the LINE position, all front panel controls are functional except the
Master Volume, and the signal is essentially the same as that heard through your speaker system. The output
level in the Line position is adjusted by the GAIN control on the front panel. If you are using an effect, this will
also appear mixed in the signal when you are in the line mode.
In the “Direct” position, the Balanced XLR out becomes an active TUBE direct box. No front panel controls arefunctional and the level is only adjustable via your instrument.
BASS 750 USER GUIDE • 7

Wiring for the XLR connector is as follows:
Pin 1 = ground, Pin 2 = +, Pin 3 = – (negative)(American Standard)

The Bass 750 is compatible with Phantom Power-equipped mixing consoles.
TUNER SENDThe Tuner Send allows the user to plug an instrument tuner into this jack and tune up without having to unplug
and go back and forth from amp to tuner. This feature is totally isolated from the rest of the preamp and willfunction regardless of the settings on the front panel. Being on a side chain (isolated) also avoids loading
down of the instrument causing a loss in dynamic range.
To use this feature, plug in a shielded patch cord from the Tuner Send output to the input jack on your tuner.
Turn the amplifier on and you’re ready to go. If you do not wish to monitor your sound during the tuning
process, switch the Speaker On/Off switch to the “off” position.

INTERNAL FEATURES
VACUUM TUBE (VALVE)SWR installs a specially selected 12AX7 dual triode tube (valve) in the preamp section of every Bass 750. If
this tube needs replacing, we recommend that you replace it with a similar high quality product. This tube will
require replacement only in the event it becomes noisy or microphonic (sounds like glass tinkling in the background of certain notes), or completely fails causing no signal.
POWER ON TRANSIENT
When the Bass 750’s power switch is moved to the “On” position, you will hear a turn-on transient (sounds
like a “thud”) through your speakers. This will not harm speakers made by SWR, however, you may wait toconnect your speaker cable to the Bass 750 until after powering up. Just make sure you are not playing
through the unit when you make the connection, as it could cause a speaker fuse to blow. Eliminating thistransient would require a component called a relay. Since relays tend to degrade signal quality and often fail,we decided not to incorporate this type of component in the Bass 750.
A FEW WORDS CONCERNING HEAT
Please be aware that the chassis of your amplifier can get quite warm during normal use. This is especiallytrue if you are using a 2.67 ohm total impedance, as this introduces the least efficient condition possible forthe unit (i.e., power drawn from the outlet in relation to power produced in the speakers). The difference inthese two figures can be quite high, basically resulting in the equivalent of putting a high wattage light bulb
inside a metal box—which would obviously get quite warm.
Furthermore, most musical instrument amplifiers on the market today utilize steel for their chassis, which inmost cases is considerably cheaper than aluminum and does not conduct heat as well. With the exception of
the front panel (which is made of steel), the Bass 750 utilizes an all aluminum chassis, which has less impurities than steel, is less susceptible to rust, and is a better conductor of heat. This results in the chassis acting
as a heatsink—drawing heat away from internal heat-producing components, thus extending their life and making the Bass 750 a more reliable amplifier.
You should be aware of a heat-related condition known as “over biasing.” If one or more of the power amplifiersin your Bass 750 becomes over biased, it may cause the unit to generate more heat than normal. This condition can be recognized by turning on your amplifier and letting it sit without speakers plugged in and without
playing it. If under these conditions your unit becomes quite warm, it may be over biased. This situation should
be attended to and can be easily remedied in about 15 minutes by a qualified technician. An amplifier canbecome over biased through continuous vibration or by any large jolt received in shipping, transportation, etc.
RACK MOUNTING INSTRUCTIONS
To preserve the beauty and reliability of your amplifier, we recommend that you install your amplifier in a rackcase. The Bass 750 is completely ready to be rack mounted and needs no additional parts or accessories
other than the case itself. The Bass 750 takes up three full rack spaces (it is 5-3/8" high). If the rack thatyou mount the Bass 750 in requires that the rubber feet on the bottom of the chassis be removed, please
remember to REPLACE the screws, as they help to reinforce the chassis.

8 • BASS 750 USER GUIDEThe Bass 750 should be mounted as close to the bottom of the rack case as possible. The height of the rubber feet was chosen so that when you slide the unit in the bottom of the rack case, the rack mounting holeson the front panel will line up with the mounting holes of the rack rail. This prevents the Bass 750 from flexing
downward if the rack case is dropped. If you must mount the Bass 750 in an area of the rack other than thebottom space, a piece of wood or similar solid material should be installed between the bottom of the rackcase and the bottom of the amplifier to prevent flexing of the amplifier’s chassis. Severe or constant flexing of
the chassis can damage the amplifier and is not covered under the warranty.
Don’t neglect your amp after it has been installed in a rack case. Continuous transportation and vibration cancause screws to become loose, both on the Bass 750 and on your rack case rails. We recommend that atleast once a month you remove the Bass 750 from the case and tighten all outside screws (especially on thefront panel). Then check all the connections in your rack case and reinstall the unit.
