FORCE OFF
With a Lo level at the FORCE OFF input, a channel is
manually forced to switch off. This input has the
highest priority:
• Overrides FORCE ON
• Overrides the activation of a channel by the
automatic mixing functions
• Overrides the holding of a channel by Last Mic On
(see "Automatic mixing functions" Page 36)
A channel switched off by Force Off has no effect on the automix algorithm

NOTE
VCA IN
With a DC signal, the overall volume can be varied.
This jack allows you to externally adjust or mute the
output level. Depending on the application, you can
use potentiometers, switches or external control
voltages for this.
If you are using an external potentiometer, the maximum adjustable volume will be determined
by the "OUT MASTER" rotary control. For the correct adjustment, the potentiometer must be
set to 100%. Thereafter, the maximum adjustable volume is limited on the "OUT MASTER"
rotary control. The potentiometer can now be used to adjust the volume below the set
NOTE
maximum value. This procedure prevents unwanted feedback.
LOGIC OUT
As soon as the microphone associated with the
channel is activated, this output is set to 0 V. It can
than be used, for example, to trigger a camera
control or activate the LED ring of a microphone.
