9 Audio inputs 1 through 6 — Each input has a 3.5 mm, 5-pole captive screw
connector for balanced or unbalanced stereo audio input. See the following
wiring diagrams to wire a connector for the appropriate input type and
impedance level. High impedance is generally over 800 ohms.

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.
