1 Chapter One Introduction About this Manual About the MTPX Twisted Pair Matrix Switchers Definitions Features PRELIMINARY MTPX Twisted Pair Matrix Switchers
Introduction About this Manual This manual contains installation, configuration, and operating information for the Extron MTPX Twisted Pair (TP) Matrix Switchers. About the MTPX Twisted Pair Matrix Switchers The MTPX matrix switcher distributes signals that are compatible with the Extron MTP and VTT/VTR product lines. The matrix switcher routes a TP input signal to any combination of TP outputs.
The MTPX switchers input and output TP signals on RJ-45 connectors. N For best results, use a cable length of at least 50' (15 m) between the TP inputs and outputs and the transmitter and receiver. Additionally, three or six (depending on the matrix size) 15-pin HD and 5-pole 3.5 mm direct insertion input connectors are available for direct RGB (VGA) or other video inputs and stereo audio inputs without an MTP transmitter.
Introduction, cont’d Transmission distances The maximum distances are determined by the frequency and resolution of the video signal being routed and which MTPX inputs and outputs (TP or local) are in the full (video source to display) routing path. The tables below and on the next page specify the recommended maximum transmission distances using Extron Enhanced Skew-Free A/V UTP cable or UTP CAT 5, 5e, 6, or 7 cable, terminated with RJ-45 connectors.

Installation, cont’d Signal inputs a Inputs (TP) connectors — Connect the TP outputs of compatible MTP or VTT transmitters to these RJ-45 female connectors. Do not connect this device to a computer data or telecommunications network. C N You must configure the switcher for the appropriate content on the audio/ RS-232 wire pair (pins 3 and 6) for each TP input. See “Defining the Audio/ RS-232 wire pair“ in chapter 3, “Operation”.
b Local (RGB) Inputs connectors — Connect analog computervideo sources to these 15-pin HD female connectors. RGB N The video that is input on this connector is converted to the proprietary TP signal that normally output by the MTP 15HD transmitters, eliminating some of the transmitters in your system. N Extron recommends against tying a local (RGB) input to a local (RGB) output; the image displayed from such a tie may be overpeaked.
Installation, cont’d N A mono audio connector consists of a tip and sleeve. A stereo audio connector consists of a tip, ring and sleeve. See figure 2-6 to identify the tip, ring, and sleeve parts of the connector when you are making connections for the switcher from existing audio cables. The ring, tip, and sleeve wires are also shown on the captive screw audio connector diagrams, figure 2-5 and figure 2-7. Tip (+) Ring (-) Tip (+) Sleeve ( ) Sleeve ( ) RCA Connector 3.
N This connector can also output HD component video, component video, S-video, or composite video if that is the video format of the tied input. Output only sync signals, no video signals, on the sync pins, 13 and 14. • For component video, use the R (R-Y) and R return pins (pins 1 and 6), G (Y) and G return pins (pins 2 and 7), and B (B-Y) and B return pins (pins 3 and 8). • For S-video, use the R, R return (C-chroma), G, and G return (Y-luma) pins.
Installation, cont’d By default, the audio ties follow the video ties. Audio breakaway, which can be activated via the front panel or under serial port control, allows you to select from any one of the audio input sources and route it separately from its corresponding video source.

Operation, cont’d Optimizing the Audio PRELIMINARY Each individual input audio level can be adjusted within a range of -18 dB to +24 dB, so there are no noticeable volume differences between sources and for the best headroom and signal-to-noise ratio. Adjust the audio gain and attenuation as follows: 1. Connect audio sources to all desired inputs and connect the local audio outputs to output devices such as audio players. See “Signal inputs”, in chapter 2, “Installation”.
Configuration Worksheets Rather than trying to remember the configuration for each preset, use worksheets to record this information. Make copies of the blank worksheet on page 3-51 (32-input button and -output button switchers) and page 3-53 (16-button switchers) and use one for each preset configuration. Cross out all unused or inactive inputs and outputs. Use different colors for video and audio.
Operation, cont’d Worksheet example 2: Daily configuration Figure 3-69 continues from worksheet example 1 by showing the video and audio ties that make up the configuration of preset 1. Black lines show video ties and red lines show the audio ties.
Worksheet example 3: Test configuration The A/V system in our fictional organization needs to be fine tuned on a regular basis. Figure 3-70 shows a typical test configuration, with an Extron video test generator (input 12) generating a test pattern to all monitors (outputs 1, 2, 4, 5, and 8). Sound checks are run from the CD player (input 5) to all audio systems (outputs 1, 2, 4, 5, and 8).
