Extron electronic MTPX Plus Series manual Local Inputs VGA connectors - Connect analog computer

B	Local Inputs (VGA) connectors — Connect analog computer-	RGB
	video (RGB) sources to these 15-pin HD female connectors.

N• The video that is input on this connector is converted to the proprietary TP signal output by the MTP 15HD

transmitters, allowing you to eliminate some of the transmitters in your system.

•Extron recommends against tying a local (VGA) input to a local (VGA) output; the image displayed from such a tie may be overpeaked.

•When either the input or output of a tie is local (VGA), Extron recommends that the MTP output or input be connected by a minimum of 50' (15 m) of TP cable to prevent overpeaking.

•The matrix switchers can also input and switch HD component video, component video, S-video, or composite video by using the appropriate adapters. No configuration of the switcher is required for component or other non-RGB video formats.

C	Audio Inputs (local audio) connectors — Connect balanced or
	unbalanced stereo audio inputs to these 3.5 mm, 5-pole captive
	screw connectors. Connectors are included with each switcher,
	but you must supply the audio cable. See figure 2-5 to wire a
	connector for the appropriate input type and impedance level.
	Use the supplied tie-wrap to strap the audio cable to the extended tail of the
	connector. High impedance is generally over 800 ohms.

CThe length of the exposed (stripped) portion of the copper wires is important. The ideal length is 3/16” (5 mm). Longer bare wires can short together. Shorter bare wires are not as secure in the captive screw connectors and could be pulled out.

CThe 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.

NSee 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. A mono audio connector consists of a tip and sleeve. A stereo audio connector consists of a tip, ring and sleeve. The ring, tip, and sleeve wires are also shown on the captive screw audio connector diagrams, figure 2-5 and figure 2-8.
