(1) Power Button & LED Indicator
The Power button switches the amplifier between ON and
STAND-BY. When ON, the Power LED lights up BLUE along
with one of the Mode LEDs. When the amplifier is on STAND-
BY,the Power LED lights up RED while the Mode LEDs are off.
Additionally, the Power LED reflects the state of the amplifier
(i.e.whether the Signal Sensing is set on ON/AUTO/+12V and
whether signal is being fed to the amplifier).
(2) Music/Movie Quick Mode Button
The Mode button switches the amplifier’s EQ between
a preset Music mode (flat) and a preset Movie mode
(+8dB between 30 - 80Hz).
Note that this feature will work only when the Main
Power switch (located on the back panel of the am-
plifier) is in the ON position.
(3) Digital Readout
This digital readout shows the gain/volume setting of the
amplifier as it is being changed, either by turning the Gain/
Volume Control knob or by pressing the +Vol/-Vol on the
remote.

(5) Gain/Volume Control
This infinite rotary knob allows the user to control the gain/
volume of the amplifier. Always start at the lowest setting and
slowly increase the volume until the desired level is reached. It
is best to use the gain adjustment on the receiver or pre-amp
to make any minor adjustments.
