For Bi-Amp operation.
AC Power On
After connecting the outputs to the loudspeakers, you may turn the amplifier on.
1. Make sure the output gain settings for all audio-source devices (CD Players, Mixers, Instruments, etc.) at the lowest output (max attenuation).
2. Turn on all audio sources.
3. Turn the AC Mains power switch on the back of the amplifier to ON. The amplifier starts in the state it was in when power was removed.
4. You can now bring up the outputs of your audio sources.
