Rear Panel Audio Inputs and Outputs
The following sub-sections describe each component on the rear panel of the DVX. Refer to FIG. 4 on page 8 for the
component layout of the rear panel.
AUDIO INPUTS (1-2)
The two AUDIO INPUTS connectors are female 1/8" stereo mini-phono jacks that receive up to two unbalanced audio
inputs (FIG. 17). 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
HDMI INPUTS (3-6)
The four HDMI INPUT connectors (ports 3-6) 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 (3-6) section on page 20. If you
are using a DVX-2155HD, you have two DXLink input ports, which support embedded audio, in place of HDMI input
ports 5-6. See the DXLink INPUTS (5-6) section on page 21 for more information.
AUDIO INPUTS
The two 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. 18). 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.
The AUDIO INPUTS are ports 7 and 8 on the DVX-2150HD/2155HD. The AUDIO INPUTS ports are ports 5 and 6 on
the DVX-2110HD.
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
