Enova DGX Audio Insert/Extract Boards

Instruction Manual – Enova DGX 8/16/32/64 Digital Media Switchers
Setting the DIP Switches
Important:
When an AIE connector is set to insert audio, audio on the corresponding video signal will always
be replaced with the input from the AIE connector. When the AIE connector does not have a valid audio signal
to insert, “no signal” is the input that will be inserted – resulting in no sound.
The individual AIE connectors on the AIE Board must have their DIP switches set according to how the audio for each
connector is to be used in the system.
Each board has two DIP switches per AIE connector with the corresponding AIE connector number displayed vertically
between the switches (labeled “Channel Setting” – see FIG. 75 below).
The DIP switch on the left is used for enabling or disabling the extract/insert functionality. The DIP switch on the right
can be set to either “extract audio from” or “insert audio onto” the signal routed on numerically corresponding standard
input or output connectors.
Important:
When disabling extraction/insertion functionality for connectors on the AIE board, use the DIP
switch settings “Disable/Extract”; do not use the settings “Disable/Insert.”
Note:
We recommend writing down the setting for each connector before reinstalling the AIE Board into the
Enova DGX enclosure. This will make verifying correct audio switching (see page 127) easier.
Enable/Disable DIP Switches
Located on the left (see blue rectangle in FIG. 75).
To enable, flip left. Enable must be selected for the insert/extract function to work.
To disable, flip right. Disable turns off the insert/extract function for that port.
Extract/Insert DIP Switches
Located on the right (see red rectangle in FIG. 75).
To extract audio, flip left. The AIE connector will pull the embedded audio signal off the corresponding
standard input or output connector’s signal (the embedded audio remains intact on the HDMI signal).
To insert audio, flip right. The AIE connector will insert the connected audio signal onto the corresponding
standard input or output connector’s signal.
When shipped from the factory, the DIP switches are set to “Enable” and “Extract.”
