Changing The Virtual Matrix - AMX DGX1600-ENC Hardware Reference Manual

Controlling Switches on Systems with Audio Switching Boards
IMPORTANT: The control panel does not have direct control of the audio signal on the Audio Switching Boards (ASB or ASB-DAN).
The analog audio signal from the Audio Switching Board must first replace the embedded audio on the HDMI signal via a
SEND_COMMAND (see page 181). Only then can the audio signal from the Audio Switching Board be switched with the video or
routed independently from the video as a breakaway.
Control of video and audio switching on systems with Audio Switching Boards (ASB or ASB-DAN) works as follows:
To switch digital video with its embedded audio, use either VM 0 (All) or VM 1 (Video).

To switch the embedded audio* separately from the digital video (as a breakaway audio signal), use VM 2. (When switching

on VM 0 or VM 1, the embedded audio is still present.)
* The embedded audio can also be analog audio from the Audio Switching Boards which has been used to replace the embedded
audio via a SEND_COMMAND (see page 181).
NOTE: Complete audio switching functionality is available via the System Configuration interface (see page 163) or via
SEND_COMMANDs (see page 181).

Changing the Virtual Matrix

Enova DGX Switchers support three virtual matrices for switching signals:
VM 0 Default (Audio follow Video)

VM 1 Video Breakaway

VM 2 Audio Breakaway

VM 0 is the factory default; we do not recommend changing the established VM numbers. If you create a custom configuration, you
will need to change the virtual matrix on the Control Panel to execute switches (or other operations) using the custom virtual
matrix.
IMPORTANT: When audio is embedded on HDMI, the audio switches on the same VM as the video (VM 0 or VM 1). If the system
contains Audio Switching Boards (ASB or ASB-DAN), embedded audio can be switched independently on VM 2. If the system does not
contain Audio Switching Boards, VM 2 is not functional.
The directions below give steps to change from routing signals on VM 0 (Default) to routing on VM 1 (Video).
To change the virtual matrix:
1. Press the Function Key.
The Function menu appears.
2. Locate Virtual Matrix by scrolling with the Control Dial.
3. Press the Select Key.
The V.Matrix list appears.
4. Scroll with the Control Dial to 1:Video.
5. Press the Select Key to enter your selection.
The display returns to the top of the V.Matrix submenu.
VM 1 becomes the new virtual matrix used for all operations.
