The ADA-8504 provides four AES outputs (BNC 1, 2, 3, and 4) for the first amplifier and three AES
outputs (BNC 5, 6, and 8) for the second amplifier.
Single Configuration Input and Output Cables
AES Input
The AES audio input should be connected to BNC IN on the rear of the frame. Set JP1 and JP2
appropriately.
AES Outputs
The ADA-8503 provides eight AES outputs (BNC 1 through 8).
