HDMI INPUTS

The HDMI INPUT connectors on the rear panel routes digital audio (and video) from connected source input devices to

the connected output devices. These inputs support the following audio formats:

For more information about these connectors, including wiring, see the HDMI INPUTS section on page 26.

If you are using a DVX-3155HD, you have two DXLink input ports, which support embedded audio, in place of HDMI

input ports 9-10. If you are using a DVX-3156HD, you have 4 DXLink ports and only 4 HDMI inputs. See the Supported

Video Settings section on page 28 for more information.

The following table lists the number of digital audio ports and the port numbers for each model of DVX.

AUDIO INPUTS

The four 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. 22). 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 (0.3162 Vrms) unbalanced

Maximum input level: 2 Vrms

Input impedance: >12k ohms unbalanced, >12k ohms balanced, DC coupled

FIG. 22 displays the AUDIO INPUTS connectors on the DVX-3150HD-SP.
