THE MOMENTUM HD PREAMPLIFIER
Interconnect cables
We recommend the use of high-quality balanced XLR audio interconnect cables with the
Momentum HD Preamplifier. If you have a source device that does not offer XLR connections,
use high-quality XLR-to-RCA adapters.
First connect the source devices (phono preamplifier, CD player, etc.) to the appropriate inputs.
Connect each XLR cable (or XLR-to-RCA adapter) to the appropriate XLR jack by pushing the
plug into the jack. To release the plug, push on the small tab atop the jack and gently detach the
plug. Never grasp interconnect cables by the cable itself—you could damage the cable. Be sure
to connect left channel to left channel, right channel to right channel.
Note that the Momentum HD Preamplifier does not incorporate a phono stage; you must add
an external phono stage in order to use the Momentum HD Preamplifier with a turntable. We
recommend the Momentum Phonostage for use with the Momentum HD Preamplifier.
Now connect the Momentum HD Preamplifier's line outputs to your amplifier. Connect each XLR
cable to the input by pushing the cable onto the jack. To release the XLR cable, push on the small
tab on the top of the plug, then grasp the cable by the plug and gently pull it out.
Power supply connector cable
The Momentum HD Preamplifier is supplied with a special power connector cable that connects
the power supply to the preamplifier main chassis. The connectors are surrounded with a collar.
To connect them, pull back on the collar, push the connector onto the jack on the power supply
or the preamplifier, then release the collar. To disconnect them, slide the collar back to unlock the
connector, then pull the connector loose. Be sure to hook up the power supply connector cable
before you connect the power supply to the AC outlet.
Remote Control Operation
The Momentum HD Preamplifier 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. Please attach the included Bluetooth antenna to the threaded
antenna input on the rear panel.
Remote Pairing
The remote control requires an initial pairing to the Momentum HD Preamplifier. Once
paired, the remote control will stay paired to the Momentum HD Preamplifier. 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 are
installed in the remote. Make sure the Momentum HD Preamplifier is plugged into the wall
and that the switch on the AC inlet is turned on. The Momentum HD Preamplifier can be on
or in standby for this pairing to take place.
If communication is lost between the Momentum HD Preamplifier and the remote control,
hold the Server and Radio buttons for 10 seconds. When you release, you will see a blue LED
flash on the remote, which indicates a re-set has been done.
AC cord
The Momentum HD Preamplifier is supplied with a high-quality AC cord tipped with a 15-amp IEC
connector at the preamplifier end and a three-conductor AC plug at the other end. You may use
a different power cord with the Momentum if you wish, as long as it is tipped with a 15-amp IEC
connector and a three-conductor AC plug.
After the speaker, interconnect cables, and power supply connector cable are connected, push
the IEC connector on the power cord into the IEC jack on the Momentum HD Preamplifier.
Do not plug the Momentum HD Preamplifier or any other Dan D'Agostino Master Audio Systems
product into a power strip or power conditioner.
12-volt trigger outputs
These 3.5mm jacks emit a 12-volt DC control signal when the preamplifier is on. You can connect
them to any devices that take a 12-volt DC control input, such as an amplifier.
RS-232 input
This DB9-type input allows the Momentum HD Preamplifier to be controlled by home automation
systems that use RS-232 protocol. Consult your D'Agostino Master Audio Systems dealer for
more information.
