A-D Inputs 5–8
XLR-3 female analogue inputs to channels 5–8 of the A-D option card.
These inputs have no function without the optional A-D card installed – however, LED meters 5–8 will still
indicate the incoming signal levels.
Channel Insert Sends & Returns
Analogue sends and returns on XLR-3 male and female connectors.
The return signal can be added into a channel path by pressing the front panel Insert switch.
