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.
After power is switched on, the Momentum 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 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
in this manual.
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 high brightness and to the right for low brightness. If the switch is in
the center position, the meter will be turned off.
Sensitivity/meter off switch: If you listen at low levels, the needle 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 30-watt sensitivity and to the right for
150-watt sensitivity. In the center position, the meter will read 300-watt sensitivity.
Maintenance
The Momentum 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. Spray a small amount of the supplied
cleaning solution onto the supplied microfiber cloth and gently wipe the amplifier's surface.
Do not spray the cleaner directly onto the amplifier.
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.
