Connecting Two Mixing Consoles
This is the most basic 8ox set up and allows the
MAIN PA and MONITOR consoles to have ac-
cess to the stage microphone signals.
The MAIN PA console connects to the DIRECT
output and supplies 48V phantom power to the
mics and active direct boxes.
The MONITOR console uses the ISOLATED out-
put and is therefore electrically decoupled from
the fi rst console. The MONITOR console may be
powered from a separate AC-mains circuit with-
out creating ground loops.
Connecting Three Mixing Consoles
This advanced setup connects three consoles
to an 8ox.
The MAIN PA console connects to the DIRECT
output and the MONITOR console to the auxil-
iary DIRECT with LIFT output. In order to avoid
hum and buzz from ground loops these consoles
should be powered from the same AC main cir-
cuit or a power distribution system designed to
prevent ground loops from forming.
A third RECORDING console connects to the
isolated output and is therefore electrically
decoupled from the MAIN PA and MONITOR
consoles. The RECORDING console may be
powered from a separate AC mains circuit with-
out creating ground loops.
