Operation

In operation, the AdderLink AV modules are designed to be completely transparent - high quality video and audio from the source PC system are played as normal, the only difference is that they are now being seen and heard up to 300 metres away.

Indicators

Brightness and sharpness adjustments

The brightness and sharpness adjustments provided on every AdderLink AV receiver allow you to compensate for any losses incurred within long cable links. These two adjustments can be made in any order and independently of each other.

When making adjustments it is necessary to have access to the AdderLink AV receiver and to be able to view one or both connected display screens. Both adjustments, sharpness in particular, are made easier when viewing high contrast images with vertical edges, such as black lines on a white background.

Adjustments

Video signals are susceptible to the effects of long distance cables and for this reason, every AdderLink AV receiver includes brightness and sharpness adjustment dials. Additionally, the AdderLink AV101 and AV200 receivers are also equipped with two extra dials to eliminate the effects of colour skew within the video image.

To adjust brightness and/or sharpness

1Carefully insert a small screwdriver into the dial labelled BRIGHT or SHARP, as appropriate.

2Slowly turn the dial clockwise or anticlockwise and observe the effect shown on the screen. Withdraw the screwdriver when the displayed image is shown at its optimum clarity.

3 If necessary, repeat step 2 for the other dial.
