PRELIMINARY
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 fl exibility — 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 fl exibility — 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
confi guration fi le at the home offi ce 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.
