DRS AES Audio – Unbalanced

project posted:

Dedicated input or dedicated output BNC connector frames for AES audio provide 64 AES digital audio channels for unbalanced signals. Each AES channel carries a pair of mono audio signals, therefore 64 AES input or output channels occupy the full 128 audio signal capacity of the frame. With input frames, audio pairs are separated and routed through DRS as two completely independent audio signals. With output frames, any two audio signals routed through DRS may be selected to form the output pair for a specific AES output channel. Each frame provides two power supply module slots. One power supply is required for frame operation; a second power supply may be added for power redundancy.

Split I/O BNC connector type signal frames for AES audio each provide 32 AES digital audio input channels and 32 AES digital audio output channels for unbalanced signals through 64 rear panel connectors. Since each AES channel carries a pair of mono audio signals, 32 input channels and 32 output channels fill the 128 audio channel capacity of the frame as 64 input signals and 64 output signals. AES digital input signal pairs are separated and routed through DRS as two completely independent audio signals. Any two audio signals routed through DRS may be selected to form the output pair for a specific AES digital output channel. Each frame provides two power supply module slots. One power supply is required for frame operation; a second power supply may be added for power redundancy.
