8 Channel Automatic Matrix Mixer
Audio Expansion In/Out
When multiple AM8/4s are used in an application, their Audio Link ports must be interconnected using the Audio Link
In/Out connectors on the rear panel of the AM8/4. The Audio Link In/Out connector is just to the right of the Program-
mable In/Out connector on the rear panel. An 8 pin mini-DIN cable is supplied with each AM8/4 for this purpose.
When installing the AM8/4s in a rack, the Master AM8/4 should be mounted in the top of the rack, with Slave AM8/4s
mounted below the Master AM8/4. The 8 pin mini-DIN cable then connects the Audio Link In connector of the Master
AM8/4 to the Audio Link Out connector of the first Slave AM8/4. If there is more than one Slave AM8/4, the Audio
Link In connector of the first Slave AM8/4 is connected to the Audio Link Out connector of the second Slave AM8/4,
and so on for as many Slave AM8/4s as exist in the system.
