Difference Between DRB Network Audio Processors:
DRB-1: No input and output audio ports, has 2 CobraNet ports. It can process 8 audio channels from the CobraNet signal.
DRB-8A: Has 8 analog audio output ports and 2 CobraNet ports. No input ports. It can process 8 audio channels from the CobraNet signal and output the

processed signals to its audio ports
DRB-206A: Has 2 analog audio input ports, 6 analog audio output ports, and 2 CobraNet ports. It can process 2 audio channels from the local audio input and 6

audio channels from the CobraNet signal, then output the processed signals to its analog output ports.
