Troubleshooting Guide
If the unit does not turn on and the power indicator LED is NOT illuminated, start
with this:
1. Check and make sure that B+ and GND are not reversed
2. Check power wire is correctly connected and have the appropriate
potential (11- 16 volts)
3. Check that the fuse is functioning correctly.
If you experience high audible distortion or low output volume:
1. Check that the input and output levels are set correctly. Input should
match the source, and output should match the sensitivity of the host.
2. Check the crossover settings; make sure they are correct; for high "Q"
system s, set the crossover half an octave above the desired point and for
low "Q" systems, put it 1 octave or more above.
If you experience whining or engine noise:
1. Verify that the GND connection is secure; the conductor (wire) is not too
thin and unnecessarily long.
2. Check that the +12V wire is not too thin and unduly long.
3. Change the power source; try connecting a different power source.
