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.
