Instruction Manual – Enova DGX 8/16/32/64 Digital Media Switchers
Attaching Audio Input and Output Wires
Enova DGX Switchers can be ordered to include an Audio Insert/Extract Board(s). The AIE Audio Board works in
conjunction with HDMI, DVI, DXLink Twisted Pair, and DXLink Fiber Boards. The inputs and outputs are configured
on a per connector basis to insert or extract audio.
Important:
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.
For specifications, connector wiring, and configuration information, see the “Audio Insert/Extract Board” chapter on
page 119.
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 shipments unless ordered otherwise. Maximum power specifications are
on each power receptacle (and are also listed on page 26). Always use earth-grounded power cords / system 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 32 system contains DXLink Twisted Pair Boards, be sure to read the section on “Power Budget
Planning” on page 93. 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 determines 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.
Power Enova DGX enclosures as follows:
Enova DGX 8/16
– Cable the power via power strip to an outlet connected to a single 20 A circuit breaker.
Enova DGX 32
– To take full advantage of the multiple power feeds and redundant power supplies, cable the
primary power feed to an outlet connected to one 20 A circuit breaker. The redundant power feed should be
cabled to an outlet connected to a second 20 A circuit breaker (FIG. 23).
Enova DGX 64
– To provide adequate power for an N+1 redundant application, connect each of the four
power supplies to its own circuit.
