AUX 1 + AUX 2 PRE/POST CHANNEL 17/18 AND 19/20
When using AUX 1 or AUX 2 to control an external effects device, bring the switch to the down position POST.
The control signal is now picked up after the channel volume controller (N 53), it is therefore dependent on
the latter. To control a stage monitor, bring the switch to the up position PRE. The signal is picked up before
the channel volume controller (N 53) and the volume of the stage monitor can be adjusted independently of
47
the channel volume.
49
AUX 3 POST CHANNEL 17/18 AND 19/20
Volume controller for adding the signal from channel 17/18 and 19/20 to an external effects device (Effect
Send, Post Fader). Use the line output AUX SEND 3 (N 12) for activation.

50
LEVEL DFX / AUX 4 POST CHANNEL 17/18 AND 19/20
49
Volume controller for adding the signal from channel 17/18 and 19/20 to the internal digital effects device
(effect send, post fader). Use the line output AUX SEND 4 (N 12) for activating an external effect. When using
the AUX SEND 4 jack socket, the internal effects device is automatically bypassed, and is therefore not usable.
51
BAL CHANNEL 17/18 AND 19/20
50
Use the balance controller to set the relative volume between the left and right part of the connected stereo
signal. When only the XLR socket or left socket L (MONO) of the line input of channels 17/18 and 19/20 is in
use, the controller performs the function of a Panorama controller.
51
52
MUTE CHANNEL 17/18 AND 19/20
To mute a channel, press down on the MUTE switch of the corresponding channel. The MUTE LED of the
selected channel then lights up. When disabling the mute function, the MUTE LED goes out.
55
52
53
FADER CHANNEL 17/18 AND 19/20
Volume controller for channels 17/18 and 19/20. Push the Fader button upwards to increase the volume of
54
the corresponding channel and
downwards to decrease it.
54
SIGNAL-LED CHANNEL 17/18 AND 19/20
The signal LED lights up as soon as an audio signal is present at the corresponding channel (depending on
the input level and setting of the gain or input sensitivity - GAIN).
56
55 CLIP-LED CHANNEL 17/18 AND 19/20
57
Once the red Clip LED lights up, the corresponding channel is operating at the distortion limit. Adjust the Gain
controller (N 41) so that the Clip LED of the corresponding channel only lights up briefly when signal peaks
occur. Avoid the permanent lighting of the Clip LED by reducing the input gain or input sensitivity; if necessary,
reduce the volume of an external audio device.
58
GR 1/2 CHANNEL 17/18 AND 19/20
56
Press down on the GR 1/2 switch to add the corresponding channel to the channel group 1 (BAL all the way
to the left), to the channel group 2 (BAL all the way to the right), or to both groups of channel groups 1 and 2
in the same proportion (BAL in central position). The signals of the channels grouped together in one group
are routed simultaneously to the corresponding line outputs GROUP OUT 1/2. The total volume of the resulting
59
group is adjusted using the volume controller GROUP 1/2 (N 104); if the audio signals of the group are to be
53
routed to the MAIN MIX sum channel, press down on the L-R switch (N 105).
57 GR 3/4 CHANNEL 17/18 AND 19/20
Press down on the GR 3/4 switch to add the corresponding channel to the channel group 3 (BAL all the way
to the left), to the channel group 4 (BAL all the way to the right), or to both groups of channel groups 3 and 4
in the same proportion (BAL in central position). The signals of the channels grouped together in one group
are routed simultaneously to the corresponding line outputs GROUP OUT 3/4. The total volume of the resulting
group is adjusted using the volume controller GROUP 3/4 (N 106); if the audio signals of the group are to be
routed to the MAIN MIX sum channel, press down on the L-R switch (N 107).
