“Phenomenal performance along withendless listening options.”
Founder, and Chief Designer of Dan D’Agostino Master Audio Systems

Thank you very much for purchasing the Momentum MxV Integrated Amplifier. We areespecially excited about this component. Combining the front-end technology from theMomentum HD Preamplifier and the power section of the Momentum MxV amplifier, itdelivers Momentum Series performance in a compact framework only hinting at the advanced
circuitry within. Employing a configurable, modular design, the core line stage section can beaugmented to include a digital streaming and/or a phonostage module. When fully equipped,
the Momentum MxV Integrated Amplifier topology is a seamless circuit working as one from
input to output, optimizing performance in a way not otherwise possible.
The heart and soul of the Momentum MxV Integrated Amplifier is essential Dan D’Agostino
Master Audio Systems’ technologies including discrete, balanced, direct-coupled circuitry
married to a substantial output stage delivering 250/500/1,000 Watts per channel into
8/4/2 Ohms, respectively. The foundation of the Momentum MxV Integrated Amplifier is a
traditional line stage integrated amplifier suitable for all analog sources except turntables.
For those listeners keen to incorporate digital playback within the same unit, an optional
digital streaming module is available, adding a full suite of capability. Coaxial, optical, and USB
physical inputs join ethernet and wireless connectivity for in-house network and internetstreaming capability. Digital resolution includes support for files up to DSD1024 and 32bit/192K
PCM accuracy. Vinyl playback has also been addressed with an optional phonostage
module adding selectable moving coil functionality. If a turntable is added in the future, thephonostage module can be added later.
As part of the digital module technologies, Tidal, Qobuz, and Spotify streaming subscription
services are available. With appropriately encoded music files, MQA decoding is standard.
Customized apps for iOS devices provide easy control of music collections, streaming
content, and unit control. Roon Music management is also available as an alternative music
management program.
From the outside, the Momentum MxV Integrated Amplifier is pure Dan D’Agostino Master
Audio Systems. The iconic Momentum Series volume control fronts the amplifier with elegantly
efficient heat sinks reminiscent of the flagship Relentless Amplifiers, providing proper coolingfor optimal operation and long-term reliability. Finished in either anodized silver or black
aluminum, the Momentum MxV Integrated Amplifier, like all D’Agostino components, is handassembled by our staff of music lovers and technicians in our Cave Creek, Arizona, facility.

UNPACKING AND INSTALLATION
Unpacking the Momentum MxV Integrated Amplifier from its case
While the Momentum MxV Integrated Amplifier is still in its case, please move it to a locationnear the place where it will be installed. Remove all jewelry including watches, rings and belts
from your person to avoid damage to the exterior of the integrated amplifier during the removal
and installation.
The finish of the Momentum MxV Integrated Amplifier is durable but can be damaged. To protect
its pristine surface, we strongly suggest wearing the supplied white lifting gloves when handlingto avoid abrasion, fingerprints caused by oils from skin, etc. See Operation: Maintenance for
instructions on cleaning.
Installation requirements
This component’s dense metal chassis makes it much heavier than most other integrated
amplifiers, so make sure the surface that will support this component can safely hold its weight.
Adequate ventilation must be provided for the amplifier. There should be at least 3 inches ofclearance on each side and 3 inches of clearance at the top. The bottom vents must not be
obstructed by thick carpet, dust, etc. We recommend that the integrated amplifier be installed
in an open equipment rack to assure proper ventilation. The amplifier may be installed in a closed
cabinet or in an equipment closet, but the space must be designed with substantial ventilation at
top and bottom; active ventilation (i.e., powered fans) is preferred.
Important: Instead of using a traditional cable, theMomentum MxV Integrated Amplifier uses a specially madeconnector located near the right front edge that joins theaudio chassis (top) and the power supply chassis (bottom). To
assemble the amplifier, place the power supply chassis in theMomentum MxV Integrated Amplifier’s final location. Carefully
place the larger audio chassis on top of the power supply
chassis. Ensure the bottom-plate connector makes solid
contact with the audio chassis top-plate connector.
If plugging the Momentum MxV Integrated Amplifier into a
power strip or power conditioner, make sure it is a high-quality unit that does not alter groundconnections or insert current-limiting elements in series with the AC mains signal.
If you need to return the Momentum MxV Integrated Amplifier for service
If you should need to return the for unit service, be sure to use the original box and materials
for shipment. Before you ship the unit, unplug it from the wall and let it cool down for 2 hours.
To protect the finish during shipping, rewrap the amplifier in the protective packaging in which it
was originally shipped. Make sure the amplifier is completely cool. Wrapping the amplifier when it
is warm will cause the plastic to leech into the amplifier’s surface and will permanently damage
the finish.

MAKING CONNECTIONS TO THE
MOMENTUM MxV INTEGRATED AMPLIFIER
Speaker cables
Install the speaker cables first. We recommend the use of high-quality cables terminatedwith spade or ring lugs that will fit the Momentum MxV Integrated Amplifier’s binding
posts. Banana plugs may also be used. Note that the positive (+) binding post has a redring and the negative (-) binding post has a black ring. Double check to confirm that you
are connecting your speaker cable’s conductors to the appropriate binding posts—red topositive, black to negative. If your cables are marked to show desired signal flow, orient thecable so that the installation conforms to the cable manufacturer’s instructions.
To install speaker cables tipped with spade lugs or rings, use a binding post wrench tocarefully loosen each speaker binding post. Turn counterclockwise to loosen. If using spadelugs, insert each spade lug so that its two tines straddle the binding post, then tighten thebinding post nut with the binding post wrench. If using rings, remove the binding post nut
entirely, place the ring on the binding post, then replace the nut and tighten it securely. A
firm connection, tight enough that the spade lug or ring cannot move, is all that’s needed.
Too much torque could damage the binding posts. Do not use a conventional wrench totighten the binding posts.
Interconnect cables
We recommend the use of high-quality balanced XLR audio interconnect cables. If you have asource device that does not offer XLR connections, use high-quality RCA cables. If you need
RCA to XLR adapters, please contact your Dan D’Agostino Master Audio Systems dealer.
Connect the source devices (phono, CD player, etc.) to the appropriate inputs. Connect the XLR
cable to the appropriate jack by pushing the plug into the jack. To release an XLR plug, pushon the small tab atop the jack and gently detach the plug. Never grasp interconnect cables by
the cable itself as it can damage the cable. Be sure to connect the left channel to left channel
and the right channel to right channel. Note: The input labeled Phono is a standard line level
input and does not include the circuitry necessary for turntable playback unless the optional
phonostage module is installed.
Optional Phonostage Module
If the optional phonostage module is installed in the Momentum MxV Integrated Amplifier,connect the turntable to the phono input. Do not connect any other source to this input if
the phonostage module is installed. The phonostage module supports moving-coil cartridges
and offers a variety of loading options via dip switches. Please consult your phono cartridge
owner’s manual for the ideal selection. Adjust the dip switches to match your phono cartridge’s
loading suggestion according to the chart below. The dip switches to adjust are inside of theMomentum MxV Integrated Amplifier. To adjust, open the top cover by removing the (10-32 x
3/8-inch) screws using a T20 Torx hex-key wrench. Inside located directly behind the phono
input button, on the inside of the front panel, is the plug-in phonostage module. There are two
dip switches that must be set the same for the cartridge that is being used.

Optional Digital Module
The optional digital module has connections for optical, coaxial, and USB digital cables. An
Ethernet connection via RJ45 and a Wi-Fi antenna input are also included. One of these must be
used as a network connection to utilize the digital module’s in-house network capability, and aninternet connection is needed to access streaming services such as Tidal, Qobuz, or Spotify. Ifavailable, we recommend using the hard-wired Ethernet connection. Alternatively, attach the
Wi-Fi antenna for wireless operation.
The Ethernet cable pushes into the connector and locks. To remove the cable, press the tab on
the underside of the connector and gently pull the cable out.
AC cord
The Momentum MxV Integrated Amplifier power supply is supplied with a high-quality AC cord
tipped with a 20-amp IEC connector at the integrated amplifier end and a three-conductor AC
plug at the other end. You may use a different power cord, as long as it is tipped with a 20-amp
IEC connector and a three-conductor AC plug. After the speaker and interconnect cables areconnected, push the IEC connector on the power cord into the IEC socket on the Momentum MxVIntegrated Amplifier. If plugging the Momentum MxV Integrated Amplifier into a power strip or
power conditioner, make sure it is a high-quality unit that does not alter ground connections or
insert current-limiting elements in series with the AC mains signal.

12-volt trigger output
This 3.5 mm jack transmits a 12-volt DC control signal. The 12-volt trigger output connects
to a 12-volt input on any device that accepts a 12-volt DC control input and will move theconnected component to/from Standby mode.
RS-232 inputThis DB9-type input allows the Momentum MxV Integrated Amplifier to be controlled byhome automation systems that use RS-232 protocol. Consult your D’Agostino Master Audio
Systems dealer for more information.

Headphone jackThis 1/4-inch jack allows connection of headphones to theMomentum MxV Integrated Amplifier. Headphones with a
1/8-inch plug may be connected using a 1/8-inch-to-1/4inch adapter. To activate the headphone output, select asource to listen to, and then press the headphone buttonon the front panel to route the signal to the headphone
output. The loudspeakers and preamp output will bemuted. To restore sound to the loudspeakers and preamp
output, press the headphone button again.
Bluetooth antenna
Please affix the included Bluetooth antenna to the screw post marked Antenna.

OPERATION
Initial power-up of the Momentum MxV Integrated Amplifier
Once the Momentum MxV Integrated Amplifier is plugged into an AC outlet, move the AC powerswitch to the on position. The unit is now in Standby mode.
Press the Standby button on the front of the Momentum MxV Integrated Amplifier. This will
power up the component and illuminate the volume indicator. After power is switched on, theamplifier requires approximately 30 minutes to reach optimal operating temperature. Although
the Momentum MxV Integrated Amplifier will sound excellent upon initial listening, the soundquality will improve as it warms up.
Basic operation
The Momentum MxV Integrated Amplifier offers basic functions on the front panel: Standby on/off, volume up/down, output options, and source selection. The remote control adds balance andpolarity operation to these front panel functions.
Standby: When the Momentum MxV Integrated Amplifier is in Standby (off) mode, the Standby
LED will be illuminated. Press the button to turn the unit on. When power is on, the Standby LED
will go off, the volume indicator and the active source will illuminate. Press the button again to
return to Standby. The volume indicator and source LEDs will go out and the Standby LED will
illuminate again.
Volume: Turn the volume knob clockwise to raise the volume and counterclockwise to lower it,or use the Volume +/- buttons on the remote. The needle in the multi-function meter indicator
will move toward the right as you increase the volume and to the left as you decrease it. We
recommend you turn the volume down when you initially power up the system and raise it only
when you are assured that all components in the system are operating properly.

8Note: The Momentum MxV Integrated Amplifier uses a high-accuracy, relay-controlled
stepped attenuator for its sound quality and excellent left-to-right gain accuracy. This highperformance volume control emits a small mechanical click as the volume setting is changed.
This is normal operation and once the changes have been made, no other sounds will bemade by the control. During normal playback, the needle indicates the selected volume.
When balance is adjusted, the needle will indicate the selected balance setting.
Source selection: Press the front-panel button or remote button that corresponds to thedesired source. The LED for the currently active source will illuminate.
Theater Mode: The Theater Mode input allows you to interface the Momentum MxVIntegrated Amplifier with a multichannel home theater audio system. To use it, connect theleft- and right-channel outputs of your surround sound processor to the amplifier’s Input 3.
By default, Input 3 is a standard input. To configure for Theater Mode, press and hold theInput 3 selector button until the volume control needle points to 70. This setting bypasses
the amplifier’s volume control, setting it at a fixed level, and uses your surround-soundprocessor’s volume control instead. The front panel and remote volume controls are disabled.
Select Input 3 on the front panel or remote when listening to surround sound. Press and holdthe Input 3 selector button to return Input 3 to normal operation.
Dark Mode: Dark Mode blanks out the multi-function meters and LEDs after 15 seconds ofillumination. The Dark Mode is selected or unselected by holding the Standby button in forseveral seconds while the unit is in Standby Mode. All front panel lights are disabled unlessa change is made on the front panel or remote to any of the controls. During a change theLEDs are illuminated but will re-extinguish shortly after the changes are made.
Remote Control Operation: The Momentum MxV Integrated Amplifier remote control uses
Bluetooth rather than typical IR operation. Bluetooth offers great improvement in usable
range and does not require line-of-sight for proper operation.
Remote Pairing: The remote control requires an initial pairing to the Momentum MxVIntegrated Amplifier. Once paired, the remote control will stay paired to the amplifier.
Re-pairing will be required when batteries are changed in the remote control.
The pairing process is automatic but requires a few seconds after a new set of batteries
is installed in the remote. Make sure the Momentum MxV Integrated Amplifier is plugged
into the wall and that the switch on the AC inlet is turned on. The amplifier can be on or inStandby for this pairing to take place. If the amplifier loses communication with the remotecontrol, only the red LED will be illuminated when a button is pressed. To repair, press
the mute and headphone buttons on the remote until the LED blinks blue multiple times
indicating the pairing process has been re-started. The LED should now be illuminated blue
when a button is pressed on the remote control.

9Polarity (remote control and RS-232 only): The Polarity control inverts the polarity of theentire system. While the Momentum MxV Integrated Amplifier does not invert polarity, manysource devices do, and many recordings are produced with inverted polarity. Because there is
no way to know what the proper polarity is, this must be set by ear. Push the Polarity buttonon the remote control to invert the polarity. The volume meter will turn from green to red when
the polarity is inverted. Try listening with the polarity normal or inverted, and use whichever
setting sounds better. Depending on the recording, the effects of polarity inversion are often
subtle and sometimes even inaudible. The multi-function meter is illuminated in red when theMomentum MxV Integrated Amplifier polarity is inverted.
Mute: The Mute control mutes the volume temporarily. Press it once to mute, and again torestore the volume. When muted, the multi-function meter will alternate between green andgreen/white; and the Mute button LED will flash on/off. If the polarity of the Momentum MxVIntegrated Amplifier is inverted, the multi-function meters will alternate between whiteand red.
Balance (remote control and RS-232 only): The Balance control lets you shift the stereo balance
to the left or right speaker. To adjust balance, press the Balance button on the remote. The
needle will swing to center and dim, indicating the current balance setting. Use the Volume +/buttons on the remote to shift the balance setting. Pressing the - button will shift the balance tothe left and the meter will move to the left as well. Conversely, pressing the + button will shift
the balance to the right along with the meter. To return the balance to the center, press andhold the Balance button on the remote. The meter will dim and after the button is held for a few
seconds the meter needles will point to center. The LED on the remote will also blink.
Basic setup for use with the Digital Module
While the Momentum MxV Integrated Amplifier can be used on its own with analog sources,
an iOS device is required to take advantage of the digital functionality. Download the free
