Audio Connections
Earth Link
The CHASSIS GROUND post is internally connected to both the case and the safety earth.
If the link is removed for technical reasons (such as earth loops), then the ANALOGUE
GROUND post must be wired separately to the installation technical earth point.
Audio Connections
Two identical sets of 3 pin XLR connectors are provided for each mic amp channel A
and B. Inputs are female, outputs are male.
All connectors follow the European wiring convention:
Pin 1 = Screen
Pin 2 = Hot (+)
Pin 3 = Cold (-)
The inputs are electronically balanced using Rupert's "TLA" transformer-like-amplifier
design. The outputs are transformer balanced, coupled using Rupert Neve's "tertiary
feedback" output stage design.
