counterclockwise to lower it, or use the Volume +/- buttons on the remote. The needle

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.

source selection: Simply push the front-panel button or remote button that corresponds

with the source you want to hear. The Led in the middle of the front-panel button for the

currently active source will light up.

theater: By using the Theater Bypass input, you can interface the Momentum preamp

with a multichannel home theater audio system. To use it, connect the left- and right-

channel outputs of your surround-sound processor to the Momentum preamp's Theater

Bypass input. This input bypasses the preamp's volume control; use your surround-sound

processor's volume control instead. Push the Theater button on the front panel or remote

when you want to listen to surround sound. Push any other source button to return the

system to stereo mode.

tone: To activate the tone controls, push the Tone button on the front panel or remote.

The Led in the middle will light up, indicating that the tone controls are active.

Bass and treble controls: When the Led in the middle of the front-panel Tone button

is on, these controls will be active. Turn them clockwise to boost, counterclockwise to cut.

The front panel indicates the level of boost or cut in decibels (dB). When adjusting these

controls, we strongly recommend you turn the preamp's volume all the way down. This is

because the preamp is dC-coupled, with no capacitors in the signal path. This design

gives the best sound quality, but it can result in some noise when the treble and bass

knobs are turned.

Phase (remote control only): The Phase control inverts the phase of the entire system.

While the Momentum preamp does not invert phase, many source devices do, and many

recordings are produced with inverted phase. Because you have no way of knowing what

the proper phase is, you must set this control by ear. Push the Phase button on the remote

control to invert the phase. The light on the preamp's front dial will turn from green to red when

the phase is inverted. Try listening with the phase normal or inverted, and use whichever

setting sounds better. If you can't hear a difference, don't worry about it. depending on the

recording, the effects of phase inversion are often subtle and sometimes even inaudible.

mute (remote control only): The Mute control simply mutes the volume temporarily. Press

it once to mute, and again to restore the volume. When the sound is muted, the light in the

volume indicator will flash.

Balance (remote control only): The Balance control lets you shift the stereo balance to right

or left. To activate it, press the Balance button on the remote. The volume indicator on the

face of the preamp will swing to show the current balance setting. use the volume +/- buttons

on the remote to change the balance setting. If the needle points straight up, the balance is

even between left and right. If the needle points to right or left, the balance is shifted to that

side. To return the balance to the center, hold down the Balance button on the remote for 2

seconds. The remote backlight will flash and the needle will return to center.

Maintenance

The Momentum preamp requires no user maintenance other than to keep it clean and

ensure that the vents remain unobstructed.

To clean the preamp, first disconnect the AC plug. Spray a small amount of distilled water

or a cleaning solution such an endust or Pledge onto the supplied microfiber cloth and gently

wipe the preamp's surface. do not spray the cleaner directly onto the preamp.

If dust or other contaminants or objects collect around the vents at the top and bottom of

the preamp, remove small objects by hand and use a shop vacuum or hand vacuum to remove

the dust. use a brush attachment on the vacuum to avoid scratching the preamp's surface.

Preamp will not power up

If the front meter is not illuminated, follow the procedure outlined below. If one step

succeeds in activating the power, stop there and ignore the other steps.

If the Led in the middle of the Standby button on the front of the preamp is lit,

push the button to turn the preamp on.

If the Led in the middle of the Standby button is not lit, check to make sure the

AC cord is plugged into the wall outlet.

Check at the back of the power supply to make sure the 15-amp IeC connector is

pushed all the way into the jack on the back of the power supply.

Check to make sure the power supply connector cable is firmly connected to the

power supply and the preamp.

unscrew the fuse at the back of the power supply. Check to see if the fuse is

blown. (The conductor inside the fuse will be severed and you may see burn

marks on the fuse.) Be sure to replace the fuse with one of the proper value.

Consult your dealer or d'Agostino LLC.

Check your household electrical box to make sure the circuit breaker has not been

tripped. If it has, flip the breaker back on.
