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.

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. MTP Series Features S-Video Transmitters MTP T SV A

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.

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. Transmitter

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).

Figure 15. Power Connector Wiring 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.

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.

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.

Mounting Options NOTE: For rack, furniture, or projector mount installation, see the instructions provided with the kit.
UL Requirements The following Underwriters Laboratories (UL) requirements pertain to the installation of the MTP transmitters or receivers in a rack. 1. Elevated operating ambient — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the device in an environment compatible with the maximum ambient temperature (Tma = +122 ˚F, +50 ˚C) specified by Extron. 2. Reduced air flow — Install the equipment in a rack so that the amount of air flow required for safe operation of the equipment is not compromised. 3. Mechanical loading — Mount the equipment in the rack so that a hazardous condition is not achieved due to uneven mechanical loading. To avoid the risk of tip-over, distribute the weight of the equipment evenly on both sides of the rack. Install equipment starting at the bottom of the rack, with the heaviest equipment near the base and lighter equipment near the top. 4. Circuit overloading — Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern. 5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (for example, use of power strips). 6. Secure, stable installation — Securely attach a rack-mountable product to the rack or floor per the installation instructions. If the rack is provided with a stabilizing device, install the stabilizer before mounting or servicing the unit in the rack.
Tabletop Use (All Except AAP Models) The non-AAP MTPs come with four self-adhesive rubber feet. Attach 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 15 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 correctly displayed) before installing the transmitter.
