Routing Audio Signals; Testing/Checking Audio Signal Routing - AMX DGX1600-ENC Hardware Reference Manual

Routing Audio Signals

Audio Routing Capability
The audio routing capability of systems with Audio Switching Boards is system dependent.
Enova DGX 800 enclosure: 16x16 audio inputs and outputs comprised of 8 audio only inputs/outputs and 8 video with

embedded audio inputs/outputs
Enova DGX 1600 enclosure: 24x24 audio inputs and outputs comprised of 8 audio only inputs/outputs and 16 video with

embedded audio inputs/outputs
Enova DGX 3200 enclosure: 40x40 audio inputs and outputs comprised of 8 audio only inputs/outputs and 32 video with

embedded audio inputs/outputs
Enova DGX 6400 enclosure: 80x80 audio inputs and outputs comprised of 16 audio only inputs/outputs and 64 video with

embedded audio inputs/outputs
In the System Configuration interface, the Audio Virtual Matrix (VM 2) is controlled by selecting the Switch Mode: Audio button.
Virtual Matrix (VM) sizes reflect the model of the enclosure. VM 2 includes audio-only signals and audio embedded on video signals:
Enova DGX 800 will have 8x8 VMs with the exception of VM2 Audio which will be 16x16

Enova DGX 1600 will have 16x16 VMs with the exception of VM2 Audio which will be 24x24

Enova DGX 3200 will have 32x32 VMs with the exception of VM2 Audio which will be 40x40

Enova DGX 6400 will have 64x64 VMs with the exception of VM2 Audio which will be 80x80

For routing purposes, the audio matrix I/O channels are numbered as follows:
A/V and Video input and output ranges cover the basic switching size of the system: 8x8, 16x16, 32x32, or 64x64

Audio only input and output ranges cover the embedded audio as part of the basic switching size of the system, plus the

audio available on the Audio Switching Boards (ASB) in the expansion slots, plus the assignment of one input as a
downmixed audio channel, which is routed as a separate input:

For switching audio only via the System Configuration interface, use the Audio Switch Mode (VM 2). When embedded audio is sent
as audio only, each signal will be numbered according to the number of the video input or output that contains the embedded
audio. Audio on the Audio Switching Boards will be numbered using the numbering scheme of the video input or output number
+1, +2, +3, etc. per product according to the table below.

The input and output numbers in the last column in the table above are the numbers used for routing the Audio Switching Board's
audio channels in the Audio Switch Mode.
For example, on an Enova DGX 800:
In the System Configuration interface, to route the source wired to the first connector on the Audio Switching Input Board

in the first input expansion slot, select the Audio Switch Mode and click Input 9.
In addition, audio embedded on an HDMI video input can be routed as an embedded audio-only signal.
For example, on an Enova DGX 800:
In the System Configuration interface, to route an embedded audio-only signal from the source attached to the third

connector on the first HDMI Input Board, select the Audio Switch Mode and click Input 3.

Testing/Checking Audio Signal Routing

Input Board – If an embedded audio signal is being replaced on a video output signal, execute a test switch using the video signal.
If you need test switch details, see page 219.
Output Board – If audio is being pulled from a video input or output signal and sent to an auxiliary audio-only destination, check
the auxiliary or supplemental audio equipment involved to be sure the audio signal is present where expected. If the system does
not handle the audio in the expected manner, see "Audio Switching Boards Troubleshooting" on page 153.
