Attaching Wires/Cables - AMX DGX1600-ENC Hardware Reference Manual

Attaching Wires/Cables

When attaching audio wires to terminal block audio connectors, you may find it easier to unplug the audio connectors before you
start. Audio Switching Boards also require an HSSI SMA cable (included when required) that attaches from the input board to the
output board (required on all enclosure models except the Enova DGX 6400). Each board provides eight balanced/unbalanced
stereo audio line-level signals. For audio connector specifications, see page 144.
Audio Switching Board Connectors
Audio Switching Boards include four audio connectors. Each audio connector is a double 5-pin captive screw terminal block
(L+, L-, Ground, R-, R+). Each board also includes one HSSI SMA connector (not used on the Enova DGX 6400).
FIG. 87
Audio Switching Boards - orientation and connectors
ASB Boards are oriented in the Enova DGX 100 Series models as follows:
Enova DGX 800 – One each horizontal input (left) and output (right) board

Enova DGX 1600 – One each horizontal input (left) and output (right) board

Enova DGX 3200 – One each vertical input (left) and output (right) board

Enova DGX 6400 – Two horizontal input boards (left and right) and two horizontal output boards (left and right)

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.
Attaching Terminal Block Audio Connectors
Important to Know When Wiring Audio Switching Board Terminal Block Connectors
ASB Boards/connectors are positioned horizontally on the Enova DGX 800/1600/6400 and vertically on the Enova DGX

3200.
Be sure to note the labeling as shown in FIG. 88. The "L" (left channel) and "R" (right channel) are each ordered:

+, -, ground, -, +.
To wire audio connectors:
1. Loosen the captive screw on the side of the terminal block connection point.
CAUTION: Connecting ASB output left and Right channels to the same point to obtain a single channel may damage the ASB Board.
2. Insert the bare or stripped wire ends into the appropriate slots.
3. Firmly tighten the screw.
