SYSTEM SETTINGS AND RESET
DIP SWITCH 1 STANDBY
To activate the automatic standby function, move DIP switch 1 to the ON position. If the standby switch is activated, the amplifier will automatically
switch to standby mode (energy consumption reduction) after approximately 20 minutes of no audio signal. If there is an audio signal again,
standby mode automatically ends and the amplifier is ready for operation again after about three seconds; the standby LED flashes white during
this time. The STANDBY LED on the front of the device is white during normal operation and red when standby mode is activated. Standby mode can
also be manually terminated by pressing the standby button on the front of the amplifier.
