AUDIO INPUTS
The AUDIO INPUTS connectors are 3.5 mm 5-position captive-wire terminals that can be wired for either balanced (differential) or
unbalanced (single-ended) stereo audio. Since the DVX allows independent switching of video and audio, video and audio inputs of
the same number do not have to be connected to the same source equipment. These connectors feature the following
specifications:
Nominal input level: +4 dBu (1.228 Vrms) balanced or -10 dBu (0.3262 Vrms) unbalanced
Maximum input level: 2 Vrms
Input impedance: >12k ohms unbalanced, >12k ohms balanced, DC coupled
FIG. 27 displays the AUDIO INPUTS connectors.

The following table lists the number of ports and the port numbers for each model of DVX.
Source devices require either balanced (differential) or unbalanced (single-ended) connections. FIG. 28 illustrates options for
wiring between sources and input connectors. More than one option can be used in the same system.

Stereo 5-terminal wiring
FIG. 29 provides details for wiring from an audio input to a an unbalanced source device that has RCA connectors. Positive and
ground wires connect to the source. You also can use a CC-3.5ST5-RCA2F 2 RCA Female to 5-Pin Phoenix Cable (
FG10-003-20
) for
this type of connection.
