Begin playing audio on the stereo, and set the zone line out
to approximately
3
/
4
volume.
3
Slowly adjust the LEVEL dial for the zone clockwise toward
the MAX setting while listening to the speakers connected to
that zone.

When the sound from the speakers becomes distorted, stop
adjusting the dial, and slowly adjust the dial counter-
clockwise again until the distortion is gone.
5
Repeat this procedure for the other zones.
Configuring the Amplifier for a DSP Compatible
Stereo
If your stereo features digital signal processing (DSP), such as a
FUSION Apollo RA770, you should use the FUSION-Link app
when configuring the amplifier for the best results.
1
Follow the instructions in your stereo owner's manual to
download the FUSION-Link app and connect it to the stereo.
2
Select the appropriate stereo, amplifier, and speakers in the
FUSION-Link app.
3
Follow the instructions in the FUSION-Link app to adjust the
configuration controls on the amplifier.
