Enova DVX-315xHD & DVX-215xHD All-in-One Presentation Switchers - Instruction Manual
The following table lists the number of digital audio ports and the port numbers for each model of DVX.
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 (FIG. 25). Since the DVX allows independent switching of 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 (0.3162 Vrms) unbalanced
Maximum input level: 2 Vrms
Input impedance: >12k ohms unbalanced, >12k ohms balanced, DC coupled
FIG. 25 displays the AUDIO INPUTS connectors on the DVX-3150HD-SP.

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. 26 illustrates options for
wiring between sources and input connectors. More than one option can be used in the same system.
