QUICK START GUIDE WITH CABLING EXAMPLE

1. Make sure that the mixer and all devices to be connected to the mixer are turned off.
2. Connect the devices to the mixer using appropriate cables.
3. Adjust the input gain of all the channels and all volume controllers for channels 1 to 23/24 and MAIN MIX to minimum. Place all equalizer con-
trollers in the central position (stop). Adjust the volume controller on the active loudspeaker to minimum. Turn on the +48 V phantom power on the
mixer only if you are using a condenser microphone.
4. Turn on the devices in the following order: microphone and keyboard (or other source devices), then the mixer and lastly the active speakers.
5. Always adjust the gain control of the channels 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 (Gain).
6. Press the L-R switch of the channels used to the down position and leave the MUTE switch in the up position, as well as the MUTE switch on the
MAIN MIX sum channel.
7. Bring the volume controllers (Fader) of the channels in use and of the sum channel MAIN MIX approximately to the 0 dB mark.
8. Now increase the volume of the active speakers for the incoming signal (e.g.speaking, singing, keyboard) to the desired level.
9. Fine-tuning can now be achieved by adjusting the volume ratios of the channels and by using the equalizer, compressors and effects device as
desired.
NOTE: When turning off the devices, please follow these steps: First, set the volume of the active speakers to minimum and turn them off, then the
mixer and connected devices can be switched off.
