Page 2 Introduction The Sima model SVS-4, 4 Input Audio / Video Switcher with Automatic Input Mode (AIM) and Volume Stabilization has been designed for the home theater, DSS satellite, DVD, audio recording as well as for background music applications. The SVS-4 has the following features: · Four A/V inputs to allow you to add more A/V sources such as DVD, satellite dish, VCR, games, etc. [. . . ] 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 steaks. Fill in the chart below to help you organize and remember what devices are connected to the inputs and outputs. Inputs From (VCR, DSS, etc. ) Composite or S-Video?#1 #2 #3 #4 Outputs A B Remember both the A and B outputs are identical. The SVS-4 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 via the SVS-4 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 SVS-4. To (TV, Receiver, etc. ) Composite or S-Video? Page 7 Figure 5 below shows a hook up showing only two input sources. Be sure you use either S-Video or composite video inputs, but not both on the same input. The one SVS-4 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 typically system Note: Remember to always connect the outputs on your VCR/DSS/DVD/etc. Likewise, connect the outputs on the SVS-4 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 just the left connector for the audio of that source; or 2) the better solution is to use a "Y" adapter (available from any electronics store) to spilt the mono signal into two signals that you feed into both the Left and Right inputs on the SVS-4. Page 8 Figure 6 below shows a system with 3 sources. It also shows using the dual outputs to allow you 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 select inputs 1, 2 or 3 (not 4 as you would be trying to record to itself) and record on the Recording VCR the video and audio from the selected source. When the Volume Stabilizer Active light is off, the audio signal is bypassed and the Volume Stabilization setting will not have any affect on the audio signal. Volume Stabilization Adjustment The Volume Stabilization circuitry lets you control the dynamic range of the audio signal to accommodate your needs. The Volume Stabilizer light must be on for this to function. The numbers around the knob show the ratio of the input signal to the output signal in db. [. . . ] Your TV is using both composite and S-Video inputs. Use only one or the other to feed into the SVS-4 or into your TV. Is the video cable connected from the device to the SVS-4?Is the device producing a video picture. [. . . ]
