Troubleshooting
Your Proceed PAV has been designed to deliver many years of satisfaction. It has
also been designed to allow an unusual amount of “customization” so as to make
it suitable in a wide variety of (possibly changing) circumstances. This flexibility
necessitates a certain amount of setup before the unit can be expected to per-
form correctly—in effect, one must inform the PAV of its environment so it may
make the right “decisions” about what it should do. Once setup is completed, the
PAV is quite simple to use. But the setup is quite essential.
It has been our experience that most difficulties encountered with the PAV are
due to improper initial setup. Please review the relevant portions of this manual
for the details of the setup procedure.
THERE SEEMS TO BE TOO LITTLE (OR TOO MUCH) BASS.
✓ Is the crossover set correctly for your speaker configuration?
✓ Are the output levels set accurately, usinga dB SPL meter?
THE AURAL IMAGE SEEMS INCONSISTENT OR VAGUE
✓ Are the output levels set accurately, using a dB SPL meter?
✓ Are your speakers closely matched to one another in tonal balance
and dynamic performance?
THERE IS A PERSISTENT HUM IN THE SPEAKERS.
✓ If it exists only with a particular input, check that source compo-
nent and its interconnecting cables.
✓ If it exists on all sources, you may have a ground loop by having
multiple ground references in your system. We suggest you ask
your dealer for assistance in isolating this problem.
MY PAV’S ON SCREEN DISPLAY HAS INDICATED THAT IT HAS DETECTED
POTENTIAL AC PROBLEMS AND REFERRED ME TO THIS SECTION OF THE
MANUAL.
✓ If this is the first time you have seen the message, you probably
don’t have to do anything. If the PAV detects an electrical problem
that might affect its operating software (an unusually strong spike
on the AC line, for example), it posts this message and reinitializes
itself automatically. Your user settings, output levels and so forth are
retained.
✓ If you see this message with any regularity, you may have a persis-
tent, severe ground loop or other AC problem that should be fixed.
We suggest you ask your dealer for assistance in isolating this
problem.
I LEFT THE PAV ON, BUT JUST RETURNED AND FOUND IT IN STANDBY.
WHAT IS HAPPENING?
✓ There was probably a power outage while you were away from the
system. During a power failure, the PAV saves all of its critical set-
tings to non-volatile memory. When power is restored, it enters the
standby mode and waits for your return.
