HOOK UP

Connect to Power .
Connect the AC adapter cable to the jack on the back of the Image Enhancer which is labeled: 6-9 vac power 600ma.
Plug the AC adapter into a 110V power receptacle.
Connectors
Both s-video (y-c) and composite video (RCA) connectors are available on the back of the Image Enhancer.
Connect Video
Connect the video output from a signal source (such as a master video deck, non-linear edit system, or video camera) to
one of the video inputs on the back of the Image Enhancer.
Connect one of the video outputs on the back of the Image Enhancer to a video input of a destination device (such as a
video recording deck or a big screen TV). If you used the composite (RCA) video input, you should use the composite
(RCA) video output, not the s-video (y-c) output.
Route Audio Separately
The Image Enhancer does not process audio. Route audio directly from the signal source to the destination device,
bypassing the Image Enhancer.

BASIC OPERATION

Set Up. Press the power button on the front of the Image Enhancer to activate the unit.
Turn all of the enhancement controls (detail, sharpness, core, black) to zero, the furthest counterclockwise position.
Make sure that only the power button is pressed in. None of the other buttons should be pressed in. Play back a tape or
feed other video source through the Image Enhancer.
Sharpness. Turn the sharpness control up and down. Observe the effect. It should increase the sharpness of edges and
the contours of objects and people. Turn the control all the way up. This should create false outlines. Obviously, this is
too much enhancement. Turn the control down to a point where the outlines cease to be objectionable and the image
appears more natural. This is the amount of sharpness enhancement generally desirable for playback or other viewing
(amounts for making recordings will be discussed later).
Split Screen Comparison. Press in the SPLIT button. This will split the image, showing the processed image on one
half of the image, while the other half is unaffected. Repeat the above use of the control, using this feature to view the
image before and after processing.
Unity Comparison. Press in the UNITY button. This will display an unprocessed image, regardless of control
settings. You can press this button in and out to compare images before and after processing, seeing the entire image as
opposed to the split screen image seen when using the SPLIT button.
Detail. Turn the sharpness control back to zero. Turn the detail control up and down. This should bring out the detailed
areas of the image. To judge the effectiveness of this control, concentrate on textures. Look for increased detail in
people's faces and hair, in the patterns in clothing, in grass lawns, masonry walls and in the far background. Turn the
control all the way up. This should make the detail look very coarse, and the image may become very noisy (snowy).
The effectiveness of this control is limited by the amount of snow and the coarseness of detail. If using a VCR, set the
detail control to the maximum position, then adjust the tracking control on the VCR for minimum snow. Turn the
