Fehlerbehebung

Problem	Mögliche Ursache	Lösung
Keine Tonausgabe	Stromanschluss nicht vorhanden oder eingeschaltet. Main Mix fader or channel faders are down. Mute button engaged on channels or main mix. Ausgangskabel nicht angeschlossen oder defekt. Lautsprecher/amplifiers not powered on or connected.	Check power connections and switch. Raise faders to appropriate levels. Disengage mute buttons. Verify all output cables are securely connected and functional. Ensure all connected audio equipment is powered on and correctly connected.
Brummen oder Rauschen im Audio	Problem mit Masseschleifen. Improper cable shielding. Gain levels set too high. Known USB interface issue (specific to some units).	Stellen Sie sicher, dass alle Geräte am selben Stromkreis angeschlossen sind, oder verwenden Sie einen Erdschleifenisolator. Verwenden Sie hochwertige, abgeschirmte Kabel. Reduce gain levels on channels and main mix. If experiencing hum when using USB, try connecting the main outputs to an external audio interface instead of direct USB connection to the computer.
Verzerrter Ton	Eingangssignal zu stark (Übersteuerung). Ausgangssignal zu hoch.	Reduce input gain until PEAK LED no longer illuminates. Lower channel faders or Main Mix fader.
Effekte funktionieren nicht	DFX to Aux/Main controls are down. Effect program not selected. Aux Send levels to DFX are too low.	Increase DFX to Aux/Main levels. Select an effect program using the Program knob. Increase the Aux Send level on the desired channel(s) to send signal to the internal effects processor.
