AC Power On
After connecting the outputs to the loudspeakers, you may turn the amplifi er on.
1. Make sure the output gain settings for all audio-source devices (CD Players, Mixers, Instruments, etc.) are at the lowest output (max attenuation).
2. Turn on all audio sources.
3. Turn the AC Mains power switch on the back of the amplifi er to ON. The amplifi er starts in the state it was in when power was removed. If the
amplifi er is in Standby or Mute All mode (Power button LED solid red or blinking), press the Power button to change the amplifi er to Run mode.
4. You can now bring up the outputs of your audio sources.
