Audio outputs
Thru output
The THRU output socket is connected in parallel to INPUT 1, it is used for “carrying through”
the pre-fader input signal to additional powered loudspeaker or subwoofer.
Mix output
The post-fader audio signals of INPUT 1, INPUT 2 and INPUT 3 are mixed and passed to MIX
OUT. The ratio of the input signals changes when the level controls INPUT 1, 2 or 3 are
adjusted. This feature allows the loudspeaker to act as a basic three-channel mixer that can
send the mix to another loudspeaker via the MIX OUT socket.
This output is laid out in GND-SENSING technology, a special pin assignment of the output
socket, offering all advantages of the balanced signal transmission, but lets you also connect
monaural plugs without a problem.
