[. . . ] Note that this only works if the composite video and S-Video inputs are two separate inputs on your TV. Otherwise the picture may be blank, black and white or have lines and streaks. The VS-712EX has buffers to prevent one output from loading the other output for best system performance. Note: Most systems have a VHF/UHF cable from an antenna or cable company going into the VCR and then a VHF/UHF cable between the VCR and TV. This is OK but you still must connect the A/V cables as shown in figures 5 and 6. Having both the VHF/UHF cable and the A/V cable would allow you to record a program off of the cable on your VCR (cable input) while watching a different program/movie from another device (DVD) via the VS-712EX on your TV via the A/V input. Don't forget, you must select the TV's A/V input (also call video input or line input on some TV brands) not channel 3 or 4 to view the output of the VS-712EX. Page 8 Fig. 5 - Basic Hook-up #1 Figure 5 below shows a hook-up with only two input sources. Be sure you use either S-Video or composite video inputs, but not both on the same input. The one VS-712EX output goes to the TV so you can watch and listen on your TV. The second output (audio only) goes to the stereo receiver so you can listen to music or surround sound audio using your stereo receiver. Figure 5, Hook-up in typical system It would be a typical configuration if you want to watch video on your TV and listen to the audio on TV or stereo receiver. Note 2:Connect L&R audio output to hear audio from TV set with stereo receiver off. Likewise, connect the outputs on the VS-712EX to the inputs on the TV/VCR/Receiver/etc. . Note: If you have one or more devices that are not stereo and have a single audio output, you have two options. 1) Use a "Y" adapter (available from any electronics store) to split the mono signal into two signals to feed both the Left and Right inputs on the VS-712EX. 2) Use just the left connector for the audio of that source. Page 9 Fig. 6 - Basic Hook-up #2 Figure 6 below shows a system with 3 input sources. It shows how you can watch video on your TV, listen on your surround sound receiver and record from the sources plugged into the VS-712EX. It also illustrates using the dual outputs to record on a VCR, watch the video on the TV and listen to the sound on a surround system. As shown below, you can record inputs 1, 2 or 3 (not 4 as you would be trying to record to itself) and record video and audio on the recording VCR from the selected source. This shows how to connect one of the outputs of the VS-712EX to the Audio and Video inputs on the VCR that you will use for recording. Figure 6, VS-712EX with recording VCR Note: Do not select the same input that the recording VCR is connected to (input 4 in this diagram) while recording or loud feedback could occur. Notes: Remember to select the A/V or AUX input on the recording VCR to record the output of the VS712EX.
