Testing/Checking Audio Signal Routing; Digital Signal Processing (Dsp) - AMX DGX1600-ENC Hardware Reference Manual



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 Dante 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.

Enova DGX 3200
Enova DGX 6400
The input and output numbers in the last column in the table above are the numbers used for routing the Dante Audio Switching
Board's audio paths 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 Dante 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 "Dante Audio Switching Boards Troubleshooting" on page 140.

Digital Signal Processing (DSP)

Once the system is installed and all devices are in their final locations, the sound can be fine-tuned for optimum performance. To
properly adjust the sound, signals need to be routed and volume will need to be adjusted throughout the process.
TIP: Before fine-tuning the system for its final location, route a few test switches to verify that the system is working correctly and to
determine what type of digital signal processing adjustments are needed.
Dante Audio Switching Boards allow for digital signal processing (e.g., input gain, volume, equalizer) on every input /output in the
enclosure.
All of the types of supported DSP settings (see the table that follows) can be adjusted using the System Configuration interface
(see page 173). They can also be adjusted with digital signal processing SEND_COMMANDs (see page 202) or DGX_SHELL
commands (see page 243).
NOTE: The only types of digital signal processing that can occur using the control panel are volume, gain, and mute on the embedded
digital audio signals only (see page 225).

Mute function on each output path
• When a muted output is un-muted, the output returns to its previously
un-muted volume
• When a volume command is sent to a muted output, the output remains muted;
when the output is un-muted, the volume returns at the new level
