ADJUSTING SPEAKER LEVEL BALANCE
The unit is equipped with a built-in test signal generator called a noise sequencer for easy balance adjustment of all
four channels. The sequencer outputs a noise signal that "travels" from channel to channel, enabling the simple
adjustment of sound level to achieve the same apparent loudness, at your listening position, from each channel.
