Wiring Stereo Audio Connectors (5-position terminal block)
The stereo audio connectors for the Octaire are pluggable 5-position terminal block. For stereo audio
signal specifications, see the "Signal Types & Specifications" chapter (page 39). If full stereo is not
required, mono audio can be used; wire either the left or right channel for all inputs and outputs.
Wiring Sources & Destinations
Source and destination devices will require either balanced (differential) or unbalanced (single-ended)
connections. FIG. 15 illustrates options for wiring between sources and input connectors and between
output connectors and the destinations. More than one option can be used in the same system. For
balanced and unbalanced wiring details, see FIG. 16.

Attaching Wires
To attach stereo audio input and output wires:
1. Unscrew the clamps on the audio connector.
2.
Insert the wires and firmly re-tighten the clamps to make secure connections.
For balanced audio wire placement, see the left wiring diagram in FIG. 16.
For unbalanced audio wire placement, see the right wiring diagram in FIG. 16.
FIG. 16 Balanced audio
Note: For stereo audio signals using twisted pair wire, connect the shield (ground) only at one
end (recommend receiving end) to minimize low frequency noise.
