Output channel
The stereo output channels are realised as XLR plugs and are labelled "OUT - MASTER L" and
"OUT - MASTER R". When headphones are in use, they should be connected to both XLR
plugs. The "OUT MASTER" rotary knob on the front is used to adjust the output level settings
for both stereo output channels.
Connection for external control
The Control In/Out jack is a 26-pin D-sub high density connector. This jack is used for
connecting external units, such as keys of microphone stations, microphone LED rings or
camera control systems.
The following table shows the pin assignments of the D-sub high density jack:
01: FORCE ON 1
02: FORCE ON 2
03: FORCE ON 3
04: FORCE ON 4
05: VCA IN
06: GND
07: GND
FORCE ON/Override
With a HI level at the FORCE ON input, a
channel is manually forced to switch on.
Overrides a disconnection by the
automatic mixing functions
Overriding of DUCKING function (see
"DUCKING" Page 46)! Channel is not
attenuated by 10 dB
A channel activated by Force On has no effect on the automix algorithm (see "Automatic
mixing functions" Page 36) Noise Detect, NST and Best Mic On.
