Tracing faults in a recording setup is often a mixture
of logical deduction and patience. Very often, the
problem is caused by something simple; a cable
which hasn’t been plugged in properly, or a faulty
cable. If you discover a faulty cable, replace it with a
new one - it’s not worth hanging onto bad cables!
