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 10
for the component layout of the rear panel.
AUDIO INPUTS (1-4)
The four AUDIO INPUTS connectors are female 1/8" stereo mini-phono jacks that receive up to four
unbalanced audio inputs (FIG. 16). These connectors feature the following specifications:
Nominal input level: +4 dBu (1.228 Vrms) or -10 dBu (0.3162 Vrms) unbalanced
Maximum input level: 2 Vrms
Input impedance: >12k ohms unbalanced, >12k ohms balanced, DC coupled
HDMI INPUTS (5-10)
The six HDMI INPUT connectors (ports 5-10) 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 (5-10)
section on
page 22. 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. See the
DXLink INPUTS (9-10)
section on page 23 for more information.
AUDIO INPUTS (11-14)
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. 17). Since the DVX-3150HD-SP
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
