5.1 Outboard Adaptor Input Connection
The DB-25 connector on the rear panel of your P/SP-1500 will accept the processed analog output of an outboard 5.1 digital adaptor such as the Parasound P/DD-1500 Digital Surround Processor (available Fall, 1996). With this advanced feature, you can play Dolby Digital AC-3 sources and keep up-to-date with the latest advancements in digital surround and home theater technology.
Audio Output Connections
Front Left and Right Channel Outputs
Connect the left and right Front/Direct outputs of your P/SP-1500 to the inputs of the two channel amplifier or multi-channel amplifier that will power your front left and right (L, R) speakers.
Center Channel Output
Connect the Center output of your P/SP-1500 to the input of the amplifier or the channel of a multi-channel amplifier that will power your center (C) speaker.
Left and Right Surround Channel Outputs
Connect the left and right Rear outputs of your P/SP-1500 to the inputs of the two channel amplifier or multi-channel amplifier that will power your left and right surround (LS, RS) speakers.
Subwoofer Output
Connect the Subwoofer output of your P/SP-1500 to the input of the power amplifier or channel of a multi-channel amplifier that will power your subwoofer or to the line input of a powered subwoofer (Sub).
Audio Only Record/Play Connections
Use these outputs in conjunction with any of the audio inputs and an audio tape deck. Connect the left and right Play/Output of your tape deck to the left and right input connectors of Audio 1, Audio 2 or Audio 3. Next, connect the left and right Rec Output of your P/SP-1500 to the left and right Audio Record/Input connectors of your tape deck.
Recording From Your P/SP-1500
You can use your P/SP-1500 for both audio/video and audio only recording with the Video 4 and Audio Rec Output connections. To record through either of these recording output connectors, simply select the source you want to record on the front panel or remote control and the P/SP-1500 simultaneously routes the audio and video to the connectors of Video 4 Rec and to the audio connectors of Audio Rec Output.
Subwoofer Control Switch
The three position Subwoofer Control switch allows you to configure the subwoofer output jack to suit your speaker system. If your front speakers are designed to run full range and you are not using a subwoofer, set the Subwoofer Control switch to the L, C, R, Full Range/Sub off position. If your front speakers are designed to run full range and you are using a subwoofer with a built in low-pass filter, set the switch to the L, C, R, Full Range/Sub full range position. If you are using a THX-approved speaker system that includes a subwoofer, set the switch to the L, C, R, Sub/THX Filters position. This activates the built-in THX designed asymmetrical low pass and high pass crossover for the subwoofer and front left, center, and right speakers. The low-pass filter for the subwoofer has a high frequency roll-off of 24 dB per octave starting at 80 Hz. The high-pass filter has a low frequency roll-off of 12 dB per octave starting at 80 Hz for the front left, center, and right speakers.
