1Power LED — When lit, this LED indicates power is applied to the MTP.

2Sharpness — Adjusts the output image sharpness for long cable runs.

3Gain control — Adjusts the brightness of the output image to compensate for long cable runs.

S-video receivers — There are separate controls for luminance

(Y) and chrominance (C) on S-video MTP receivers. If the chrominance setting on the MTP receiver’s S-video output is too low, the image may appear in monochrome. Adjust the S-video gain until color appears.

Composite video receivers — There is only one gain control on composite video MTP receivers.

All control knobs are removable to limit access if desired.

Troubleshooting — Skew Delay Compensation

CAT 5 TP cable can cause registration errors (in which luminance leads or lags chrominance) between the Y and C video signals on S-video transmitter/receiver pairs. Try using the following methods to minimize or eliminate pair skew:

Switch to Extron’s Enhanced Skew-Free A/V UTP cable.

Add an S-video-to-BNC adapter and a skew compensation cable equal to the length of pair skew to the receiver’s output.

Install an S-video-to-BNC adapter and an SEQ 100 BNC Skew Equalizer on the receiver’s video output and adjust the skew for the leading video image.
