AES INPUTS - Three 75
Ω
BNC connectors will accept an AES3 digital audio stream.
AES OUTPUTS - Four 75
Ω
BNC connectors output the up-mixed AES3 digital audio stream.
AES SYNC - Two 75
Ω
BNC connectors that allow UpMix to receive an AES REF or DARS clock signal
from an external source and pass it on to other devices in the same stack.
The AES-3id-1995/SMPTE 276M standard dictates a 75
Ω
unbalanced connection and requires proper
termination. The termination should occur at the destination of the signal (that is, on the inputs to
UpMix). If the loop-through BNC connectors are not feeding additional equipment, terminate each of
these with a standard 75
Ω
terminator. Like other inputs, AES SYNC signal should be terminated.
GPIO – A Female DB-9 connection that allows UpMix to be monitored or controlled externally. Opto-
isolated inputs will be triggered by a voltage of 5VDC.

Output 1:
Relay 1 is Normally Open. Upon a hardware failure (i.e. Power Supply or Internal
Communications Failure), the relay will close. When the failure is remedied, the relay will open.
Output 2: Relay 2 is Normally Open. Upon an AES lock loss failure, this relay will close. When the
failure is remedied, the relay will open.
