There are two audio inputs with individual control on the rear panel. Each audio input has its
own GAIN control to adjust the sensitivity level. Higher sensitivity will lower the dynamic range
of input signals, which may result in more noise and feedback problem. Please set the
sensitivity at a proper level.
