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 1

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 transmitter output is compatible with any

S-video receiver in the MTP family described in this manual if the transmitter
and receiver jumper configuration are compatible.

• The video portion of any composite video transmitter output 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 portion of any transmitter output (whether it is equipped with either

captive screw or RCA input connectors) is compatible with any audio receiver
in the MTP family described in this manual if the transmitter and receiver
jumper configuration are compatible.

MTP AV Series • Introduction 2

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.

Figure 15. Power Connector Wiring

WARNING: 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.

• If the transmitter and receiver are separated by greater than 200 feet

(61 meters) of STP/UTP/FTP cable, connect a power supply to both units.

This remote power application is only available in stereo mode, not mono
mode.

• 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.

Captive Screw Connector

MTP AV Series • Installation 11

CAUTIONS: • 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.

NOTE: 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.

The following Underwriters Laboratories (UL) requirements pertain to the installation of the

MTP transmitter or receiver into a rack.

1. Elevated operating ambient — If the equipment is installed in a closed or multi-unit

2. Reduced air flow — Installation of the equipment in a rack should be such that the

3. Mechanical loading — Mounting of the equipment in the rack should be such that a

equipment nameplate ratings should be used when addressing this concern.

should be maintained. Particular attention should be given to supply connections (such
as the use of power strips) other than direct connections to the branch circuit.

Tabletop Use (All Except AAP Models)

The non-AAP MTPs come with four self-adhesive rubber feet. Attached one to each of the
four bottom corners. Set the MTP on a horizontal surface.

Frame Mounting (AAP Models)

The MTP T AV AAP transmitters can be mounted to any Extron AAP mounting frame that

accepts a double space (double height) AAP module (see “AAP Accessories” on page 17
for a partial list of AAP devices).

NOTE: The rear panel MTP connections will be inaccessible after installation. Make all

connections (see “Transmitter and Receiver Throughput Connections” on
page 9) and test the twisted pair system (apply a video source and observe that
transmitted video is displayed satisfactorily) before installing the panel-mounted
transmitter.
