INPUTS

Audio inputs 1 through 6 — Each input has a 3.5 mm, 5-pole captive screw connector for balanced or unbalanced stereo audio input. Connectors are included with each System 7, but the user supplies the audio cable. See the following wiring diagrams to wire a connector for the appropriate input type and impedance level. High impedance is generally over 800 ohms.

Connect the sleeve to ground (Gnd). 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 chapter three, “Operation and Configuration”, for information on adjusting the audio output level via LCD menu and front panel controls. See chapter four, “Serial Communication”, for information on using the Simple Instruction Set (SIS) commands and the Windows-based control/configuration program to adjust audio levels and to set audio breakaway.

The Fixed audio output and the Variable audio output are simultaneously active, therefore two devices can be connected at the same time. Both outputs carry the same input’s audio signal.
