Extron electronic MVX 88 Series manual Video and audio output connections

Video and audio output connections

B	RGB video output connectors — Connect RGBHV video
	displays to these 15-pin HD female connectors for each output.

NThe MVX switchers can also switch RGBS, RGsB, RsGsBs, or component/HDTV video.

NThe MVX switchers do not alter the video signal in any way. The signal output by the switcher is in the same format as the input.

C	Balanced or unbalanced audio output connectors — These 3.5 mm, 5-pole
	captive screw connectors output the selected unamplified, line level audio.
	Connect audio devices, such as an audio amplifier or powered speakers.
	Figure 2-4 shows how to wire the captive screw audio connector. The
	connector is included with the interface, but you must obtain the cable.
	Insert the wires into the appropriate openings in the captive screw connector.
	Tighten the screws on top to fasten the wires. Use the supplied tie-wrap to
	strap the audio cable to the extended tail of the connector.

Figure 2-4 — Captive screw connector wiring for audio output

CConnect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

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 direct insertion connectors and could be pulled out.

NFigure 2-4 shows two methods of wiring the connectors for output. A mono audio connector consists of the tip and sleeve. A stereo audio connector consists of the tip, ring, and sleeve. If you are wiring a captive screw connector from an existing unbalanced audio cable, the white insulated wire is typically the left channel (tip) and the red insulated wire is typically the right channel (sleeve). There is no reliable standard for existing balanced audio cables.

The audio level for each input can be individually set, via the front panel or RS-232, to ensure that the level on the output does not vary from input to input. See chapter 3, “Operation”, and chapter 4, “Remote Operation”, for details.

By default, the audio follows the video switch. Audio breakaway, which is commanded via the front panel, via RS-232 control using SIS commands or the Windows-based control program, or via optional IR 501 control, allows you to select from any one of the audio input sources. For details, see chapter 3, “Operation”, and chapter 4, “Remote Operation”, and refer to the IR 501 User’s Guide.
