AES INPUTS - Three 75Ω BNC connectors will accept an AES3 digital audio stream.
AES OUTPUTS - Four 75Ω BNC connectors output the up-mixed AES3 digital audio stream.
AES SYNC - Two 75Ω 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.
The AES-3id-1995/SMPTE 276M standard dictates a 75Ω 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 75Ω 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.
