About the MTP Transmitters and Receivers
The Extron MTP T 15HD A transmitter and 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 are a part of the Extron compact line of basic distribution amplifiers, switchers,
transmitters and receivers, and associated video accessories.
High resolution video on a 15-pin HD connector as well as stereo audio on a 3.5 mm stereo
jack is sent to the MTP transmitter. 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 transmitted proprietary signal is sent to the receiver 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 (A series only; RS series outputs
on a RS-232 connection).
The receiver also buffers the proprietary input signal and sends it to another compatible
MTP receiver or to a daisy chain of receivers.
NOTES:
• The transmitter provides pre-peaking, which boosts the signal before it is
transmitted. The buffered output on the receiver does not provide any
pre-peaking control. The total recommended distance (see the table on page 4)
for an entire daisy chain is the same as for a single transmitter and receiver. The
Pre-Peak switch on the transmitter has the same effect 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 twisted pair output of the transmitter 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 commonly encountered when CAT 5, 5e, 6,
7, or STP201 cables are used for RGB video, component video, and S-video transmission.
NOTE: An SEQ receiver should not be necessary when Extron Enhanced Skew-Free AV
UTP cable and non-C7 transmitters and receivers are used.
Each MTP transmitter and receiver model is shipped with an external desktop 12 V power
supply that accepts 100 VAC to 240 VAC, 50-60 Hz input.

Twisted Pair 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.
