Audio inputs
Balanced audio inputs. Pin 1 and 3 of the XLR connector should be linked together when
the mixer only has unbalanced outputs. The mixers' signal can be connected to pin 2, and
the ground to pin 1.
Audio outputs
Connect the power amplifiers here. Connect pin 2 (signal) and pin 1 (ground) when the
power amplifier does not have balanced inputs.
External attenuator
This input can be used to reduce the maximum sound pressure level with an external
potentiometer. The maximum sound pressure level can be reduced by connecting a linear
10kOhm potentiometer between pin1 and pin 14.
This can be useful to reduce the sound pressure level from behind the bar. It is also
possible to automatically reduce the sound pressure level, for instance when in the summer
some doors are opened.
