Stereo Audio Signals

All Octaire systems with an audio enclosure route stereo audio signals. If full stereo is not required, the Octaire can be used for mono audio; wire either the left or right channel for all inputs and outputs.

For information on wiring the connectors for balanced or unbalanced connections and on wiring sources and destinations, see “Attaching Inputs & Outputs” on page 21.
