Listed below are common problems you may encounter, and solutions.
I can’t hear the source from a channel thru the main mix!
Check the
Trim
knob, fader, and output volume on your source.
Check the
Mute
button, or make sure your sub groups are assigned to the mains.
Check your connection from the source to the device.
Try the same connection on a different channel with the same settings.
I hear noise in mix!
Check your power. A 60 Hz hum could come from ungrounded equipment.
Turn all the faders down one at a time and the stereo return knob. If the noise goes
away, it’s that channel or the source. Disconnect the source from the device, bring up
that fader: if the noise is gone it’s your source. If it’s the source, try bringing down its
output volume.
I have no power!
Make sure your power supply is properly hooked up to the unit.
I can’t hear the mix on my headphones or my control room monitors!
Check the phones / control room knob and select the proper source.
