Troubleshooting
Your Proceed Digital Surround Decoder 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 perform correctly—in effect, one must inform the system
of its environment so it may make the right “decisions” about what it should do.
Once setup is completed, the system is quite simple to use. But the setup is quite
essential.
It has been our experience that most difficulties encountered with the PAV/PDSD
system are due to improper initial setup. Please review the relevant portions of
this manual for the details of the setup procedure.
I CAN’T SEEM TO GET A DIGITAL LOCK ON THE INCOMING SIGNAL.
✓ Is the selected button properly defined and connected, with the
source turned on?
✓ Are you using a high quality cable? (RF demodulators, in particular,
require a low capacitance cable—some “audiophile” cables may not
effectively transmit the signal to the PDSD!)
✓ Some transports turn off their digital outputs when in Stop—try
pressing Play.
✓ If you are using a power line conditioner, bypass it and plug the
PDSD directly into the wall outlet. (Some line conditioners “float”
the ground connection, which can adversely effect performance.)
THERE SEEMS TO BE TOO LITTLE (OR TOO MUCH) BASS.
✓ Is the low frequency cutoff set correctly for your speakers?
✓ Are the output levels set accurately, using a dB SPL meter?
✓ Are all the loudspeaker phased properly with respect to one an-
other?
THE AURAL IMAGE SEEMS INCONSISTENT OR VAGUE
✓ Are all the loudspeaker phased properly with respect to one an-
other?
✓ 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.
