Below are examples of VCR Composite Color Video Output (previously recorded from an analog cable channel) applied to the modulator. The modulator output (RCA jack) was connected to the TV's standard 75 input jack. You can't hear the audio but it worked perfectly too.
The modulator's analog inputs are sensitive. I used a pair of 1K trimmer pots to adjust my VCR's video and audio levels.
The picture produced with a direct connection to a DVD player, video game or digital camera will be broadcast quality.
Experienced technicians will find hook-up a snap. This listing has all the information you need.
3D FUN for ADVANCED VIEWERS only
These two images represent a three dimentional (3D) view of the RF modulator assembly. The pictures are similar, but were actually taken from two different positions, approximating the spacing of your left and right eyes. In other words, the picture on the left is what your left eye would see and ditto for your right eye. Special viewing equipment helps, but is not at all necessary to see the composite 3D image.
I guarantee that once you get the hang of it, you'll understand how really very simple it is to see the 3D image.
With your left eye closed, position your right hand so you can see the full right image with your right eye, but block the left image totally. Hold that. Now, with your right eye closed, position your left hand so that your left eye can only see the left image. Double check each eye separately a couple of times to make sure that they can only see their respective image. Now the tricky part. Open both eyes and focus. You just have to practice. I can't help you any more at this point. Once you trick your eyes to focus on the two pictures as one image, you will see a single composite 3D image. Honestly!
