Introduction
Congratulations on your purchase of this precision audio component and thank you for your selection of
Parasound. Your P/DD-1500 incorporates high-quality full 20 bit decoders, filters, and D to A
converters to process Dolby Digital encoded material to provide you with an unbelievable home theater
experience. Although we designed the P/DD-1500 for control by the companion P/SP-1500 A/V
Processor/Preamplifier, it can also be used with many other processors that have six discrete inputs.
Please take the time now to read these instructions thoroughly to fully appreciate the advanced
capabilities of your P/DD-1500 Digital Decoder. Be sure to refer to the P/SP-1500 Owner's Manual. It
contains much of the information regarding connecting, setup and operation of both units.
Unpacking and Placement of Your P/DD-1500
Carefully unpack your P/DD-1500 and remove all the enclosed accessories including the remote control,
DB-25 interconnect cable, and detachable AC cord. Be sure to inspect the unit for any possible shipping
damage. If you see any, contact your Parasound Dealer immediately. Save all of the packing material
including the outer carton in case you ever need to ship the unit.
Locate the P/DD-1500 near your P/SP-1500 to allow for easy connection with the provided DB-25
interconnect. Keep your P/DD-1500 out of direct sunlight because it could interfere with its remote
control sensor. You should also keep the unit away from heat sources such as hot air ducts or radiators.
Before you proceed, find the serial number located on the rear panel of your unit and record it for
reference:
