A	Power LED — When lit, this LED indicates power is applied to
	the MTP.
B	Sharpness — Adjusts output image sharpness to compensate
	for long cable runs.
C	Gain 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 S-video gain until color appears.

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

NAll control knobs are removable to prevent unauthorized access to the adjustments.

Troubleshooting — Skew Delay Compensation

CAT 5 TP cable can cause registration errors (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 Enhanced Skew-Free A/V UTP cable.

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