6 P/DD-1500 Owner's Manual
Making Connections to Your P/DD-1500
Refer to Figure #1
Precautions
Before making any connections, be sure to turn off the power to your P/DD-1500, P/SP-1500 and especially your power amplifiers. Also, make sure there is no strain or tension on any connections that could cause them to pull loose.
AC Line Cord Receptacle
The AC receptacle accepts the AC cord supplied with your P/DD-1500. Plug the female end of the AC cord firmly into the AC receptacle and make sure that it is properly seated.
Input Connections
Your P/DD-1500 comes equipped with four inputs: one RF, two 75 Ω digital coaxial inputs and a digital fiber-optic Toslink.
RF Input
Connect the RF output of your Dolby Digital equipped laser disc player to this input. The P/DD-1500 has a built-in RF demodulator that processes the audio signal stored on Dolby Digital encoded laser discs. The demodulated RF signal is then decoded by the P/DD-1500. If the laser disc was encoded with two channel information, you will only be able to select the Dolby Pro Logic or Two Channel stereo modes for playback. If it was recorded with 5.1 channels of information, the P/DD-1500 will automatically select the Dolby Digital mode and play back all 5.1 channels of audio.
75 Ω Coaxial Inputs
The two coaxial inputs on the P/DD-1500 receive the digital signal from CD, DVD players and other digital components with 75 Ω coaxial outputs. If the source material has been encoded with Dolby Digital, the digital signal bypasses the RF demodulator and is sent directly to the digital processing circuitry for Dolby Digital decoding. Connect the coaxial output of your DVD player, DSS receiver, or other digital source to either of the coaxial inputs. If the digital source was encoded only with two channel information, you will be able to select only the Dolby Pro Logic or Two Channel stereo modes for playback. If it was recorded with 5.1 channels of information, the P/DD-1500 will automatically select the Dolby Digital mode and play back all 5.1 channels of audio.
Fiber-Optic Toslink Input
The fiber-optic input on the P/DD-1500 receives digital signals from many DVD players and other digital components with Toslink output connectors. If the source material has been Dolby Digital encoded, the digital signal bypasses the RF demodulator and is sent directly to the digital processing circuitry for Dolby Digital decoding. Connect the Toslink output of your DVD player, DSS receiver, or other digital source to the Toslink input. If the digital source was encoded with two channel information, you will only be able to select the Dolby Pro Logic or two channel stereo modes for playback. If it was recorded with 5.1 channels of information, the P/DD-1500 will automatically select 5.1 channels of Dolby Digital sound.
Audio Output Connections
5.1 Audio Output/Control Connection
The DB-25 connector on the rear panel of your P/DD-1500 sends the processed 5.1 channel analog audio output to the matching DB-25 input connector of the P/SP-1500 AV Processor/Preamplifier. The P/SP-1500 is then used for calibration, bass management, and level adjustment. Use the provided DB-25 interconnect cable to connect the two units together. Once you have made this connection, secure the connectors to the P/SP-1500 and P/DD-1500 with the connector screws.
