Enova Digital Media Switchers - 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 Audio Switching Boards will be numbered using the numbering scheme of
the video input or output 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. See the
section on page 70 for details.
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 174.
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.
NOTE:
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.
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 137). They can also be adjusted with digital signal processing SEND_COMMANDs (see page 231) or
DGX_SHELL commands (see page 273).
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 255).
