Adjusting input audio gain and attenuation

Audio/video switchers have input audio gain and attenuation adjustments. In Audio Setup mode the audio gain or attenuation of each input can be adjusted through a range of –18 dB to +10 dB. This adjustment range ensures that there is no noticeable volume difference among sources. It also eliminates the need for separate preamps or attenuators when used with professional (higher line level) and consumer (lower line level) audio equipment (figure 3-30).
