Troubleshooting
1) No Power (no lights work)
• Is the power supply plugged in (both ends)?
• Is the mains power on?
2) The microphone doesn’t work
• Is it connected to the correct (XLR) input on the rear panel?
• If it is a condenser microphone, is the phantom power switched on?
• Is the ‘Line’ switch out (LED off)?
• Is the ‘Input Gain’ control turned up?
• Is the ‘Output Gain’ control turned up?
3) The line input doesn’t work
• Is the source connected to the correct (jack) input on the back of the unit?
• Is the ‘Line’ switch in (LED on)?
• Is the ‘Input Gain’ control turned up?
• Is the ‘Output Gain’ control turned up?
4) The compressor doesn’t work
• Is the ‘Comp’ switch in (LED on)?
• Is the ‘Compress’ control turned up enough?
• Is there enough signal, as set by the ‘Input Gain’ control, to drive the
compressor?
5) Too little or too much compression
• Turn the ‘Input Gain’ control up or down respectively, to adjust the
signal level to the compressor
6) The Meequalizer doesn’t ‘t work.
• Is the ‘EQ’ switch in (LED on)?
• Is ‘Input Gain’ control turned up?
• Is ‘Output Gain’ control turned up?
7) Too much noise
• Is the ‘Input Gain’ control too high? Try moving the mic closer to the
source
• Is the ‘Output Gain’ control too high (eg: when lots of compression is
being used)?
• Is there too much EQ boost?
• Is the noise already present in the input signal? (Try removing the
input)
8) Sounds distorted
• Is the ‘Input Gain’ control too high?
• Is the ‘Output Gain’ control too high?
• Is there too much EQ boost?
• When using the compressor, is the Release control set too low?
