MTP AV Series • Introduction 1
Introduction
This section introduces the MTP transmitters and receivers. Topics discussed in this section
are:
• About the MTP Transmitters and Receivers
• TP Cable Advantages
• Transmission Distance
About the MTP Transmitters and Receivers
The Extron MTP transmitters and receivers provide a system for long-distance distribution
of NTSC, PAL, or SECAM video and audio. The MTPs transmit and receive over the
Extron Enhanced Skew-Free AV UTP cable, 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 line of basic distribution amplifiers, switchers,
transmitters, receivers, and associated video accessories.
The MTP transmitters input and the receivers output S-video (luminance [Y] and
chrominance[C]) or composite video.
Audio input is either balanced or unbalanced audio on captive screw connectors as well
as unbalanced audio on RCA connectors. The transmitters sum the left and right audio
channels to convert the audio to mono (L+R) format.
NOTE: MTPs can be configured for stereo audio output.
The MTP transmitter then converts the input video and mono audio signals (if applicable)
to proprietary signals and outputs them to the compatible MTP receiver on an RJ-45
connector.
Each transmitter requires a compatible receiver. The table on page 2 shows the video and
audio capabilities of each model, the transmitter and receiver compatibility, and Architectural
Adapter Plate (AAP) mountability.
The MTPs ship with external desktop 12 V power supplies that accept 100 to 240 VAC,
50-60 Hz input. If jumpers are repositioned from the default settings, a single power supply
can power both units if there is less than 200 feet (61 meters) of STP/UTP/FTP cable
between the two.
MTP AV Series • Introduction 2
TP Cable Advantages
Twisted pair (TP) cable is much smaller, lighter, more flexible, and less expensive than coaxial
cable. These TP products make cable runs simpler and less cumbersome. Termination of
the cable with RJ-45 connectors is simple, quick, and economical.

Transmission Distance
Extron suggests a minimum transmission distance of at least 50 feet. The maximum
transmission distance when using Enhanced Skew-Free AV UTP cable or UTP CAT 5 cable,
terminated with CAT 5 rated connectors, is 1000 feet.
NOTES:
• It is possible to exceed the recommended distance, however, image quality may be
reduced.
• The transmitters and receivers are designed for and perform best with Extron
Enhanced Skew-Free AV cable. CAT 5 cables are acceptable, but are less
preferable. We also recommend the use of preterminated and tested cables when
possible. Cables terminated on site should be tested before use to ensure that they
comply with Category 5 specifications.
• The video portion of any S-video output by the transmitter is compatible with any
S-video receiver in the MTP family described in this guide if the transmitter and
receiver jumper configuration are compatible.
• The video portion of any composite video output by the transmitter is compatible
with any composite video receiver in the MTP family described in this guide if the
transmitter and receiver jumper configuration are compatible.
• The audio output of any transmitter (captive screw or RCA) is compatible with
any audio receiver in the MTP family described in this guide if the transmitter and
receiver jumper configuration are compatible.
MTP AV Series • Installation 3
Installation
This section describes the installation procedures, including:
• Signal Jumpers for Generational Compatibility
• Panel Features and Connections
CAUTION: Installation and service must be performed by authorized personnel only.
Signal Jumpers for Generational Compatibility
Over time, the MTPs have been redesigned, affecting the signal content of the TP cable wire
pairs, changing the audio from stereo to mono, and eliminating the remote power capability.
The new-generation units are not compatible with the old generation unless an internal
jumper in the new unit is shifted.
Shift the jumpers for the new transmitter, receiver, or both if:
• Your installation mixes a transmitter and receiver from different generations.
• You want the units to transmit stereo audio.
• You want one unit to remotely power another.
Use the table below to identify the generation (revision level) of the transmitter and receiver
in your installation. If any of the above scenarios are true, reconfigure the jumpers for the
units before mounting the units.
NOTE: Only the new generation units have these jumpers.

CAUTIONS:
• The length of the exposed (stripped) portion of the copper wires is important.
The ideal length is 3/16 inches (5 mm). Longer bare wires can short together.
Shorter bare wires are not as secure in the direct insertion connectors and
could be pulled out.
• The captive screw audio connector can easily be inadvertently plugged
partially into one receptacle and partially into an adjacent receptacle. This
misconnection could damage the audio output circuits. Ensure that the
connector is plugged fully and only into the desired input or output.
NOTES:
• When making connections for the MTP using existing audio cables, see
figure 10 to identify the tip, ring, and sleeve wires in various connectors.
• A mono audio connector consists of the tip and sleeve.
• A stereo audio connector consists of the tip, ring, and sleeve.
• The ring, tip, and sleeve wires are also shown on the captive screw audio
connector diagrams (see figure 9 and figure 17).

CAUTION: The two power cord wires must be kept separate while the power
supply is plugged in. Remove power before wiring.
NOTES:
• If the transmitter and receiver are either older generation units or jumper
configured to the stereo audio position (compatible with the older units), only a
single device needs to be powered in a two-unit system (see “Signal Jumpers
for Generational Compatibility” on page 3). The device connected to the
power supply, in turn, provides power to its counterpart. This remote power
application is only available in stereo mode, not mono mode.
• If the transmitter and receiver are separated by more than 200 feet (61meters)
of STP/UTP/FTP cable, connect a power supply to both units.
• Do not tin the stripped power supply leads before installing the captive screw
or direct insertion connector. Tinned wires could be pulled out because they are
not as secure in the captive screw and direct insertion connectors.
MTP AV Series • Installation 12
ATTENTION:
• Power supply voltage polarity is critical. Incorrect voltage polarity can damage the
power supply and the MTP. Identify the power cord negative lead by the ridges on
the side of the cord (see
figure 15).
• The length of the exposed (stripped) copper wires is important. The ideal length
is 3/16 inches (5 mm). Longer bare wires can short together. Shorter wires are
not as secure in the captive screw connectors and could be pulled out.
To verify the polarity before connection, plug in the power supply with no load and
check the output with a voltmeter.
Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.
NOTES:
• Your transmitter/receiver pair may have shipped with a blue captive screw
connector. This blue connector can be plugged into either a blue or an orange
power receptacle.
• The blue connector does not have an extended tail or the included tie-wrap.
Alternatively, an optional Extron PS 124 Universal 12 VDC Power Supply (part number
60-1022-01) can power multiple Extron 12 VDC devices using only one AC power
connector.

ATTENTION:
• Connect the sleeve to ground ( ). Connecting the sleeve to a negative (-)
terminal will damage the audio output circuits.
• The length of the exposed (stripped) portion of the copper wires is important.
The ideal length is 3/16 inches (5 mm). Longer bare wires can short together.
Shorter bare wires are not as secure in the direct insertion connectors and
could be pulled out.
d RCA audio connectors (RCA models) — Connect a stereo audio device to these
L(eft) and R(ight) RCA connectors.

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.
Composite video receivers — There is only one gain control on composite video MTP
receivers.
S-video receivers — There are separate controls for luminance (Y) and
chrominance(C) on S-video MTP receivers. If the S-video output chrominance setting
on the MTP receiver is too low, the image may appear in monochrome. Adjust the
chrominance (C gain) until color appears.
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 AV 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 15HD Skew Equalizer on the
receiver video output and adjust the skew for the leading video image.
