● Amplifier, Mixer, Connection Problems
Symptom
Possible Cause
• Is the amplifier/mixer power turned on?
• Is the amplifier/mixer volume set to an appropriate level?
• Are the VL1 outputs properly connected to the amplifier/mixer
inputs?
• Are the connection cables shorted, open, or otherwise faulty?
• Is the VL1 connected to a high-sensitivity microphone or instru-
ment input on your amplifier or mixer? Try turning the VL1
DOWN controls down to avoid overloading the amplifier/mixer
inputs.
