Owner's Manual 444

Troubleshooting

Problem: No signal when an amplifier (AMP1-4) is chosen.

Make sure all amp inputs and speaker outputs are properly connected. Never mix amp

in- and outputs to different amplifiers!

Problem: No effect signal when switching FX loop.

Make sure the FX Loop of the chosen amplifier is connected correctly to the 444s

matching FX Loop. For example, if AMP1 is chosen, the AMP1 FX SEND and RETURN

have to be connected to the same amplifier, which is connected to AMP1 INPUT and

AMP1 OUTPUT of the 444!

Problem: No amp can be selected.

Check the display for its status while pressing the AMP1-4 button, when showing (n.c.)

a cabinet hasn't been selected. Activate a CAB1-4 button and try again.

Problem: No cabinet can be selected.

Check if the chosen cabinet and cable is connected properly.

Also check the cable and/or speakers for any defects.

Problem: drastic volume increase or decrease in reverb or delay spillovers when

switching between amplifiers with FX loop option.

The send and return levels of the connected amplifiers have to be set equally. Most

often the send level is controled by the channel volumes, sometimes a separate send

level is present

Problem: Cracking noise when switching FX on and off.

No proper grounding at the FX loop circuit. Pushing the FX LOOP GND LIFT switch will

solve the issue in almost any case.

Problem: erratic behaviour when switching via MIDI Control Changes.

Check if the correct CC Mode is set (see page 11)

Problem: No function when switching via MIDI.

Check if the correct MIDI channel has been set (see page 11)
