Inputs and outputs are electronically balanced and con-
nected via 3-pin XLRs and follow the wiring convention:
PIN 1 = Screen
PIN 2 = In-phase signal (hot)
PIN 3 = Out-of-phase signal (cold)
The 0.25” TRS jack connector for the external input is
unbalanced:
TIP = LEFT
RING = RIGHT
SLEEVE = Screen
IMPORTANT NOTE: Pin 1 on XLR connectors and the
‘sleeve’ connections on the jack sockets are connected
to the FRAME. This is to ensure that the console can
comply with the Electromagnetic Compatibility (EMC)
directive.
