To adjust the gain setting, turn the amplifier gains all the way down. Turn the source unit volume
up until distortion is audible and then turn it down a bit until the distortion is inaudible. Next, turn
the amplifier gain setting until once again distortion is audible and then back it down until the
distortion is inaudible.
