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.
