CAUTION

Connect the sleeve to ground. Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

The gain can be set separately for each input channel so that there is no audible difference in level when switching between inputs. See the section “Audio Configuration”, in this chapter, for information on adjusting the audio output level via LCD menu and front panel controls. See chapter three, “Serial Communication”, for information on using the Simple Instruction Set (SIS) commands and the Windows-based control program to adjust audio levels and to set audio breakaway.
