Problems ?
The channel is routed but there is no audio
. If it is assigned to a VCA group check that the group fader is up.
The audio groups do not work
. Check the setting of the fader master 1-4 mode switches.
The PAN control does not work
. Check the setting of the BLEND control.
The console takes a long time to power up
. Check the rear panel slide switch. RS232 takes longer to boot than MIDI.
