14 P/DD-1500 Owner's Manual
Maintaining Your P/DD-1500
Your P/DD-1500 requires no periodic maintenance and has no user serviceable parts inside. To avoid the
risk of electric shock, do not remove the top cover. Clean the chassis with a soft cloth moistened only
with glass cleaner or water; never use solvents or abrasives. Inspect the batteries in the remote control
annually and remove them if you do not plan on using the unit for extended periods of time.
P/DD-1500 Troubleshooting Guide
No Power
Make sure the AC cord is properly seated in the IEC AC receptacle on rear panel.
No Output to One or All Channels
Make sure that P/DD-1500 indicators are on.
Check power amplifier(s).
Check source material encoding
If the
Lock LED is on:
Check DB-25 connection between the P/SP-1500 and P/DD-1500
Check connections between P/SP-1500 and amplifiers
If the
Lock LED is not on:
Insure that a digital source is connected and playing
Problems Selecting Desired Processing Mode
Check source material encoding to make sure it can be player in the selected mode
If the material was encoded in 5.1 channel Dolby Digital, you can only select Dolby Digital or stereo
If the material was not recorded in two channel or Dolby Surround, you can only select Dolby
Digital
Hum in Speakers
Check for a grounding problem with the cable TV system; call your cable operator or installer.
Consider installing a cable isolation device such as the Video Link #634 or the Mondial Magic
Lights on Front Panel are Working, but No Control Via Remote Control or Front Panel.
The microprocessor within either or both the P/DD-1500 or P/SP-1500 may have “locked up” due to
an AC voltage spike. Remove power cord from outlet for 30 seconds and plug it back in.
Check to make sure that AC outlet is always live and not switched off
Remote Control Won't Work
Check for front panel operation to verify problem is not with P/DD-1500 unit itself
Check remote batteries
Check for interference from sunlight or neon, halogen, or fluorescent room lighting
If All Else Fails
If you cannot get your P/DD-1500 to operate properly after referring to the troubleshooting guide, call
your Parasound dealer or Parasound Technical Service. We may be able to suggest other diagnostic tests
you can easily perform. If we determine that your P/DD-1500 should be returned to Parasound or an
Authorized Parasound Warranty Center for inspection and possible servicing, call us for the phone
number and location of a warranty center near you. If you choose to send it to Parasound, contact us to
obtain a Return Authorization (RA) number. You will be asked to repack the unit in its original
packaging plus the additional outer box for protection during transit. The Return Authorization number
must be clearly marked on the outer carton only. You should ship the unit by UPS with adequate
insurance. You must also include a copy of your purchase receipt to verify your ownership and purchase
date.
Units that arrive without your specific Return Authorization number, without a suitable shipping carton
or evidence of improper internal packing must be refused. We do not accept collect shipments. After
repair under warranty, the unit will be returned to you via prepaid UPS. In the case of an out of warranty
repair, contact us and we will advise you of the repair and shipping charges before you ship the unit to
us. The same packaging and RA number requirements apply.
