Features

Video — The switcher inputs and outputs RGBHV or RGBS (VGA) video on 15-pin HD connectors. It can also switch RGsB, RsGsBs, component/HDTV, S-video, or composite video.

Bandwidth — The MVX switcher provides a minimum of 300 MHz (-3 dB) video bandwidth, fully loaded.

Audio inputs — The switcher inputs and outputs balanced or unbalanced stereo audio on 3.5 mm, 5-pole captive screw terminals.

Audio input gain/attenuation — Individual input audio levels can be adjusted so there are no noticeable volume differences between sources. Users can set the input level of audio gain or attenuation (-18 dB to +24 dB) via the front panel of the RS-232/RS-422 link.

Audio output volume — The audio volume of each output can be displayed and adjusted through a range of full output to complete silence, from the front panel or under RS-232/RS-422 control.

Switching flexibility — Provides individually buffered, independent matrix switched outputs with audio follow and audio breakaway for audio models.

•Tie any input to any or all outputs

•Quick multiple tie — Multiple inputs can be switched to multiple outputs simultaneously. This allows all displays (outputs) to change from source to source at the same time.

•Audio follow — Audio can be switched with its corresponding video input via front panel control or under RS-232/RS-422 remote control.

•Audio breakaway — Audio can be broken away from its corresponding video signal. This feature allows any audio signal to be selected with any video signal simultaneously to one or all outputs in any combination. Audio breakaway switching can be done via front panel control or under RS-232/RS-422 remote control.

Operational flexibility — Operations such as input/output selection, setting of presets, and adjustment of audio levels can be performed on the front panel or via the RS-232/RS-422 link. The RS-232/RS-422 links allow remote control via a PC or control system.

•Front Panel Controller — The front panel controller supports input and output selection, preset creation and selection, and audio gain and attenuation and volume control (audio models). The front panel features slots for labels that can identify each input and output with text or graphics.

•Windows-based control program — For RS-232/RS-422 remote control from a PC, the Extron Windows-based control software provides a graphical interface and drag-and-drop/point-and-click operation. The Windows-based control program also has an emulation mode that lets you create a switcher configuration file at the home office and then download it for use by the switcher on site.

•Simple Instruction Set (SIS) — The remote control protocol uses Extron’s SIS for easy programming and operation.

•Remote control panels and keypads — The matrix switchers are remote controllable, using the optional MKP 2000 and MKP 3000 remote control keypads. The remote control devices are easy to use and provide tactile buttons for quick selection.
