About this Manual
This manual details the installation and operation of the
following products:
• MTP T 15HD A twisted pair (TP) transmitter
• MTP R 15HD A receiver
• MTP RL 15HD A receiver with loop-through
• MTP RL 15HD A SEQ receiver with loop-through and
skew equalization
In this manual:
• The term “transmitter” refers specifically to the
MTP T 15HD A transmitter.
• The term “receiver” refers to any of the three receiver
models.
• The term “RL receiver” refers to either of the receiver
models with loop-through — the MTP RL 15HD A or
MTP RL 15HD A SEQ.
• The term “SEQ receiver” refers specifically to the
MTP RL 15HD A SEQ receiver with skew equalization
capabilities.
About the MTP Transmitters and Receivers
The Extron MTP T 15HD A transmitter and MTP R 15HD A,
MTP RL 15HD A, and MTP RL 15HD A SEQ receivers are a
system for long-distance distribution of VGA or other high
resolution video and audio. The MTPs transmitters send video
and audio over Extron’s Enhanced Skew-Free
™
A/V UTP cable
or over Category (CAT) 5 shielded twisted pair (STP),
unshielded twisted pair (UTP), or foil shielded twisted pair
(FTP) cable.
The MTPs are a part of the Extron VersaTools
®
line of basic
distribution amplifiers, switchers, transmitters and receivers,
and associated video accessories.
The MTP transmitter inputs high resolution video on a 15-pin HD
connector and stereo audio on a 3.5 mm stereo jack. The
transmitter sums the left and right audio channels to convert the
audio to mono (L+R) format. The MTP T then converts the
input video and mono audio signals to proprietary signals and
outputs them to the compatible MTP receiver on an RJ-45
connector. A pre-peaking control allows you to boost the
transmission distance of the proprietary signal. The transmitter
also makes the input video available for local use on a 15-pin HD
connector.

The receiver inputs the transmitted proprietary signal on an
RJ-45 connector and converts the signal back into its high
resolution video and mono audio components. The receiver
outputs the video on a 15-pin HD connector and the two sets of
identical mono audio signals on a single 3.5 mm captive screw
connector.
The RL receiver also buffers the proprietary input signal and
sends it to another compatible MTP receiver or to a daisy chain
of RL receivers.
The transmitter provides pre-peaking, which boosts the
signal before it is transmitted. The RL receiver’s buffered
output does not provide any pre-peaking control. The
total recommended distance (page 4) for an entire daisy
chain is the same as for a single transmitter and receiver.
The transmitter’s Pre-Peak switch has the same affect on
the recommended transmission distance for a daisy chain
as for a single transmitter and receiver.
Up to eight receivers can be connected in series using
Buffered Output connectors, provided that the total
distance from the transmitter’s TP output to the last
receiver in the chain does not exceed the recommended
distance for the resolution being used.
The SEQ receiver also corrects the skew delay (misconvergence)
commonly encountered when CAT 5, 5e, or 6 TP cables are used
for RGB video, component video, and S-video transmission.
An SEQ receiver should not be necessary when Extron
Enhanced Skew-Free A/V UTP cable is used.
Each MTP transmitter and receiver model is shipped with an
external desktop 12 V power supply that accepts 100 to 240
VAC, 50 Hz or 60 Hz input.
TP cable advantages
Twisted pair cable is smaller, lighter, more flexible, and less
expensive than coaxial cable. Termination of the cable with
RJ-45 connectors is simple, quick, and economical.
Transmission distance
The maximum distance is determined by the frequency and
resolution of the signal that is input to the transmitter. The
following table specifies the recommended maximum
transmission distances and transmitter Pre-Peak switch
positions (see item
5
on page 13) using Extron Enhanced
Skew-Free A/V UTP cable or UTP CAT 5 cable, terminated with
CAT 5 rated connectors.
