Wiring Audio Inputs And Outputs; Applying Power And Startup - AMX DGX1600-ENC Hardware Reference Manual

Wiring Audio Inputs and Outputs

Enova DGX Switchers can include the following audio expansion boards: Dante Audio Switching Boards (ASB-DAN), Audio
Switching Boards (ASB) or Audio Insert/Extract (AIE) Boards. Audio expansion boards work in conjunction with HDMI, 4K HDMI,
DVI, DXLink Twisted Pair 4K, DXLink Twisted Pair, and DXLink Fiber Boards. The inputs and outputs are configured on a per
connector basis to route audio into, out of, or through the system.
CAUTION: Audio Switching Boards, Dante Audio Switching Boards, and Audio Insert/Extract Boards are not compatible. Do not
install mixed types of expansion boards in the same enclosure. If two types of boards are present, the audio subsystem is disabled.
IMPORTANT: Audio Insert/Extract Boards Only – Setting the DIP switches is the only mechanism for configuring insert/extract
functionality on the Audio Insert/Extract Board. Therefore, setting the switches (which requires removal of the board from the
enclosure) needs to be done at the time of installation setup.

Applying Power and Startup

The enclosure's universal power receptacles will accept all major international standard power sources. Two US power cords are
included with all enclosures shipped within the US. Maximum power specifications are on each power receptacle (and are also
listed on page 28). Always use earth-grounded power cords and equipment with an Enova DGX Switcher.
The source electrical outlet(s) should be installed near the enclosure, easily accessible, and properly grounded. Power should
come from a building branch circuit. We strongly recommend using a dedicated line for the system's power. Use a minimum breaker
current rating of 20 A for 110 V or 10 A for 230 V for each circuit. To avoid an overload, note the power consumption rating of all
the equipment connected to the circuit breaker before applying power.
Power Budget Planning for Systems with DXLink Twisted Pair Boards
If an Enova DGX 3200 system contains DXLink Twisted Pair Boards, be sure to read the section on "Power Budget Planning" in
board chapter. The power draw for the system should be calculated in order to maintain the power redundancy of the power
supplies in the enclosure. Calculating the power draw also helps determine how many DXLink Transmitters and Receivers can be
powered via the switcher.
Complete Power Redundancy Setup
IMPORTANT: For proper redundant operations, all power supplies must be powered at all times.
Enova DGX 800/1600/3200 – To take full advantage of the multiple power feeds and redundant power supplies, cable the primary
power feed to an outlet connected to one circuit breaker. The redundant power feed should be cabled to an outlet connected to a
second circuit breaker (FIG. 24).
