Introduction, cont'd
A low resolution video matrix switcher system requires a MAV Plus Video BME for
each video plane (three BMEs for component video, two BMEs for S-video, or one
BME for composite video). To add audio to the system requires a MAV Plus Stereo
or Mono Audio BME.
N Multiple QS-FPCs are unnecessary and potentially confusing. To avoid
The matrix switchers are solutions to complex wideband or low resolution video
and/or audio routing applications. Each input and output is individually isolated
and buffered, and any input(s) can be switched to any one or all outputs with
virtually no crosstalk or signal noise between channels.
The audio BMEs input and output audio on 3.5 mm, 5-pole (stereo BME) or 3-pole
(mono BME) captive screw terminals.
For matrix switcher systems with video and audio BMEs, the audio switching can
either be linked with the video (audio follow) or independent of the video (audio
breakaway). Adjustable input audio gain and attenuation compensates for level
differences between audio inputs.
The matrix switcher system can be remotely controlled via its local area network
(LAN) Ethernet port and/or RS-232/RS-422 port on the rear of the primary BME
(BME 0). The matrix switchers are programmed with Extron's Simple Instruction
Set™ (SIS™), a set of basic ASCII code commands that provide simple control
through a control system or PC without programming long, obscure strings of code.
SIS commands can be entered via either the Ethernet link or the RS-232/RS-422
link.
The LAN port can be connected through a LAN or wide area network (WAN).
The switchers feature e-mail notifi cation of maintenance or other concerned
personnel concerning the status of the power supplies and the loss or resumption of
sync on individual inputs.
The RS-232/RS-422 port can be connected to a control system, a PC, or any of the
Extron remote control panels, such as the MKP 2000 or MKP 3000.
The matrix switchers are housed in rack-mountable, metal enclosures with 19" rack
ears. Each video and sync BME model is housed in a 6U enclosure. The MAV Plus
audio BMEs are housed in a 7U enclosure. The appropriate rack mounting kit is
included with each switcher.
Each model has two, primary and redundant, internal 100 VAC to 240 VAC,
50/60 Hz auto switchable power supplies that provide worldwide power
compatibility and redundant dependability. The power supply wattages are as
