Cable connections

The console offers numerous, highly flexible possibilities for balanced or unbalanced connection of
professional audio equipment. To avoid interfering noise, switch off the mixer or set the channel fader and
output controls to minimum prior to connecting and disconnecting equipment. Be sure to use only high-grade
cables. The illustrations below show the wiring of these cables.

Powering up

To protect your audio equipment, specifically your speakers, follow this power-up sequence: Set all output
volume controls of any equipment to minimum. Switch on your audio sources first, then the mixer. Always
switch on amplifiers last. Then turn up the volume control on your sources (if provided) and set the output
volume of the mixer to a low level. Turn up the volume controls of your amplifier(s) slowly. Make adjustments
to all volume settings as needed. For switching off, follow the inverse sequence: always switch off amplifiers
first, then the mixer and then the audio sources.
