Wiring & Cabling Audio Connectors
Note:
Typically, a Precis HT system uses one set of audio connectors. For information on
switching both the analog and digital audio sets of connectors (on VM 0), see page 56.
Standard Audio Connectors
The stereo audio connectors for the Precis HT are pluggable 5-position terminal block. For standard
audio specifications, see page 33.
Wiring Sources & Destinations
Source and destination devices require either balanced (differential) or unbalanced (single-ended)
connections. FIG. 14 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. 15.
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. 15.
For unbalanced audio wire placement, see the right wiring diagram in FIG. 15.
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.
