Making Connections to Your P/SP-1500
Refer to Diagram on Page 6
Input Connections
Before making any connections to your P/SP-1500, be sure to turn off the power to your amplifiers.
Also, make sure there is no strain or tension on any connections that could make them pull loose.
Audio/Video Input Connections
Your P/SP-1500 comes equipped with four audio/video line inputs, three audio-only inputs, plus a six
channel discrete input for an external digital surround adaptor. All seven inputs are compatible with any
typical analog line level source such as a compact disc player, digital to analog converter, tuner, tape
deck, or the audio output of a laser disc player or video cassette recorder. The four audio/video inputs
also have switching capability for both NTSC composite video or S-video. You may use just the audio
jacks of any of the audio/video inputs if your system needs to accommodate more audio than video
source components.
Video Inputs 1-3 (Playback Only)
Connect the audio and video outputs of any audio/video source such as a laser disc player, video cassette
recorder, satellite receivers, etc. to these inputs. This input has accompanying S-video or composite
video connections, but it does not provide an audio/video record output. If your video cassette recorder
has only a mono output you can use either the left or right audio input jack of your P/SP-1500.
However, the internal circuitry will not produce surround effects from mono signals.
Video Input 4 (Record and Playback)
Use this input for to the video cassette recorder you also intend to use for recording. The Video 4 input
has accompanying composite and S-video switching and full audio/video recording output capability.
Its record input accepts signals from any of the other six line inputs. Connect the left and right audio
output connectors from the video cassette recorder you will use for recording to the Video 4 Play
connectors of the P/SP-1500. Next, connect the left and right audio input connectors of the video
cassette recorder you will use for recording to the Video 4 Rec connectors of the P/SP-1500.
Audio 1-3 (Audio Only)
Connect a line level source to these audio-only inputs such as a compact disc player, digital to analog
converter, tuner, or tape deck.
S-Video and Composite Video Connections
Your P/SP-1500 has both composite RCA and S-video circuits with separate video amplifiers for each of
the four audio/video inputs. If you connect a video signal to one of the RCA composite input
connectors, the signal will only be available through the RCA composite Monitor and Video 4 Record
output connectors. Likewise, if you connect a video signal to the S-video input, the video signal will
only be available through the S-video Monitor and Video 4 Record output connections.
Connecting the Television Monitor or Video Projector
Connect the RCA composite or S-video Monitor output connector of your P/SP-1500 to the input
connector of your monitor or projector. If you have a monitor with a separate S-video and composite
inputs, connect the P/SP-1500 S-video output to one of the monitor’s inputs (such as External 1) and the
composite output to another input (such as External 2). This way, you can view both composite or S-
video sources by selecting External 1 or External 2 on your video monitor or projector.
