PESA offers two connector choices in dedicated input or dedicated output frames for balanced analog audio signals. Each frame provides 128 analog audio channels through either ELCO block style connectors or 6-pin pluggable style connectors. Input analog audio signals are converted and routed through DRS in the same digital format as AES signals – and may be selected as a source for analog or AES output channels. Any DRS input signal, whether digital or analog, may be selected for output as an analog signal. Selected signals, regardless of input signal format, are converted to analog format through the analog output frame. 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 signal frames for balanced analog audio are available with two connector style choices. Each frame provides 64 analog audio input channels and 64 analog audio output channels through either ELCO block style connectors or 6-pin pluggable style connectors. The entire 128 audio channel capacity of the frame is filled with the combination of input and output signals.
