AES INPUTS
- Four 75
Ω
BNC connectors will accept an AES3 digital audio stream with 1 AES-3/AES-
11 input for external AES sync and 1 AES-2 PCM input for EAS/CAP.
(1 HD/SDI Input is available as
an option)
•
1/2 - Left and Right Channel
•
3/4 - Center and LFE
•
5/6 – Left and right Surround
•
7/8 – AUX/EAS
AES OUTPUTS
- Four 75

AES SYNC
- Two 75
Ω
BNC connectors that allow MultiMerge2 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 75
Ω
unbalanced connection and requires proper
termination. The termination should occur at the destination of the signal (that is, on the inputs to
Multimerge 2). If the loop-through BNC connectors are not feeding additional equipment, terminate
each of these with a standard 75
Ω
terminator. Like other inputs, HD/SDI signal should be terminated.
HD/SDI
- Optional (SMPTE 292M/229M) with measurement and mapping of all 16 SDI audio channels
ALARM
– A Female DB-9 connection that allows MultiMerge2 to be monitored externally.
