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 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
be either 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 any of the following
ports on the primary BME (BME 0):
• Rear panel Local Area Network (LAN) Ethernet port
• Rear panel Remote RS-232/RS-422 port
• Front panel Configuration (RS-232) port
The matrix switchers are programmed with the Extron Simple Instruction Set
(SIS
a control system or PC without a need to program long, obscure strings of code.
SIS commands can be entered via the LAN port or either serial port.
The LAN port can be connected through a LAN or wide area network (WAN).
The switchers feature e-mail notification of maintenance or other interested
personnel about the status of the power supplies and the loss or resumption of sync
on individual inputs.
The Remote RS-232/RS-422 port and the Configuration 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-inch
rack ears. Each video and sync BME model is a 6U enclosure. The MAV Plus audio
BMEs are 7U enclosures. 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 power supplies that provide worldwide power compatibility and
redundant dependability. The power supply wattages are as follows:
