AC Power On
After connecting the outputs to the loudspeakers, you may turn the amplifier on.
1. Make sure the outputs levels on all audio source devices (CD players, mixers, instruments, etc.) are all the way down.
2. Turn on all the audio sources.
3. Turn on the AC mains power switch on the back of the amplifier. The amplifier will resume the state it was in when power was removed. If the
amplifier is in Standby or Mute All mode (Power button LED solid red or blinking), press the Power button to change the amplifier into Run mode.
4. You can now raise up the output levels of the audio sources.
