Typical Hook up

Step 1

Connect the AC adapter to 120 VAC and plug the DC cord into the 15 VDC input on the rear of the VS-

502.

Step 2

You will need to determine how you want to use your system. We have provided two sample hook-up

diagrams to help you determine how to connect the components of your system. You can use the last page of this manual as an organizer for your equipment. Read the following notes before installing the

VS-502 into your system.

 Note: The VS-502 does not convert analog audio to digital audio or vice versa.

If you have a combination of standard composite video (RCA type jacks) and S-Video (mini-din jacks) on your equipment you can only feed one or both cables to any given input of the VS-502.

Option 1: For ease of use, the VS-502 has a composite to S-Video converter. You can feed a combination of composite and S-Video to the VS-502 and feed only a S-Video signal to your TV. This lets you use just one S-Video input on your TV and all sources will automatically be displayed there.

Option 2: Additionally, the VS-502 has a S-Video to composite converter. You can feed a combination of composite and S-Video to the VS-502 and feed only a composite signal to your TV. This lets you use just one composite input on your TV and all sources will automatically be displayed there.

Option 3: The VS-502 has a composite to component converter. You can feed a combination of composite, s-video and component to the VS-502 and feed only a component signal to your TV. This lets you use just one component input on your TV and all sources will automatically be displayed there.
