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 Plus 128 VGA A switcher provides a minimum of
300 MHz (-3 dB) video bandwidth, fully loaded.
Audio inputs — Input and output stereo audio, balanced or unbalanced, is
provided 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. You can set the
input level of audio gain or attenuation (-18 dB to +24 dB) via the Ethernet
link, either serial port, or the front panel.
Audio output volume — The audio volume of each output can be displayed and
adjusted through a range of full output to completely silent, from the front
panel or via serial port or Ethernet control.
Digital Sync Validation Processing (DSVP™) — In critical environments or
unmanned, remote locations, it may be vital to know that sources are active
and switching. Extron’s DSVP confirms that input sources are active by
scanning all sync inputs for active signals. DSVP provides instantaneous
frequency feedback for composite sync or separate horizontal and vertical
sync signals via the switchers’ serial port or LAN port. The frequency
information can be displayed on any control system or in a Windows
®
-based
control program on a local-area network (LAN) or Internet (IP) connection
(figure 1-2).
