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. The volume will always return to minimum level when you switch
input sources.
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 in white, 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.
