11 FRONT PANEL STANDBY/POWER BUTTON: Press this button to
operate the amplifier. Press again to place the amplifier in
Standby mode. The small orange POWER INDICATOR LED will
illuminate when the amplifier is operational. When the POWER
INDICATOR LED is not illuminated, all amplifier inputs are muted
and internal circuitry reverts to power-saving (Standby) mode.
Anomalous operating conditions will place the amplifier in
Standby mode and will prevent the amplifier from being
switched back on again until such a condition is eliminated.
To avoid spurious noises, the amplifier should never be turned on
if the inputs on the rear panel are not connected.
Note:
Note: All ON/OFF power switching should be initiated ONLY with
this button. The amplifier should never be disconnected from
AC power without first placing the amplifier in Standby mode.
