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

b Sharpness — Adjusts the output image sharpness 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-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.

NOTE: 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 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 output.

• Install an S-video-to-BNC adapter and an SEQ 100 15 HD Skew Equalizer on the receiver

video output and adjust the skew for the leading video image.
