Initial power-up of the amplifier
The power button is located on the front underside edge of the amplifier. Pressing the
button will power up the amplifier and illuminate the power meter.
After power is switched on, the Momentum Stereo amplifier requires approximately 30
minutes to reach optimal operating temperature. Although the amplifier will sound excellent
upon initial listening, the sound quality will improve as it warms up, much as the flavor of a
fine red wine improves if it is allowed to breathe for a few minutes.
During operation
The Momentum Stereo amplifier requires no adjustments during normal operation. If there
is no sound or the sound quality is in some way impaired, consult the "Troubleshooting" section.
Power meter settings
Two toggle switches on the back panel control the brightness and sensitivity of the power
meter. In order to prevent accidental operation, these switches are partially recessed.
Use your finger to gently move the switches.
Brightness switch: This switch has three positions. Move it to the left (when looking at the amp
from the rear) for hight brightness and to the right for low brightness. Center the light is off.
Sensitivity switch: If you listen at low levels, the needles on the meter will not move
dramatically; this switch allows you to get more action out of the meter. Move the switch to
the left (when looking at the amp from the rear) for 100-watt sensitivity and to the right for
50-watt sensitivity. In the center position, the meter will read 200-watt sensitivity.
Maintenance
The Momentum Stereo amplifier requires no user maintenance other than to keep it clean
and ensure that the vents remain unobstructed.
To clean the amplifier, first disconnect the AC plug. Do not use polish or cleaners on the
Momentum Stereo's chassis. Use the supplied high-performance 3M microfiber cloth and
gently wipe the amplifier's surface to remove dust. Do not use a circular motion. You can
lightly moisten the cloth with distilled water if necessary to remove fingerprints. A normal
dusting cloth will not scratch the surface, but any stitching on the edges of the cloth could
scratch the surface of you apply strong pressure.
If dust or other contaminants or objects collect around the heat sink venturis or the vents at
the top and bottom of the amplifier, 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 amplifier's surface.
