About the Media Presentation Matrix Switcher

A media presentation switcher combines multiple A/V switchers, of different video formats,
and a program audio switcher with mute controls in one unit.
A matrix switcher distributes any input to any combination of outputs and can route multiple
input/output configurations simultaneously.
The MPX 866 A media presentation matrix switcher combines three matrix switchers with
the following switching capabilities in a single product:

z

z

An 8-input by 6-output VGA matrix switcher, comprising the computer video group
(computer inputs subgroup and computer/audio outputs subgroup)

z

z

A 6-input by 6-output S-video and composite video matrix switcher, comprising the low
resolution video group (low resolution video inputs subgroup and low resolution video
outputs subgroup)

z

z

A 14-input by 6-output primary audio matrix switcher

NOTE: Video ties can only be made within the same group.

Audio ties can only be made to outputs in the computer/audio subgroup
(outputs 1 through 6).

The switcher is a solution to complex simultaneous computer video, low resolution video,
and audio routing applications. Any input(s) within one of the two groups, computer video
and video, can be switched to any one or all outputs within that same group. Each input
and output is individually isolated and buffered; switching is accomplished with virtually no
crosstalk or signal noise between channels.
The computer video group has a minimum bandwidth of 300 MHz (-3 dB).
The low resolution video group has a minimum bandwith of 150 MHz (-3 dB).
The MPX inputs and outputs computer (VGA) video in the computer video group on 15-pin
HD connectors. The switcher inputs and outputs S-video and composite video in the low
resolution video group on female BNC connectors. The MPX inputs and outputs balanced or
unbalanced stereo or mono audio on 5-pole, 3.5 mm captive screw connectors.
The audio switching can either be linked with the video (audio follow) or independent of the
video (audio breakaway). The 14 audio inputs can be switched along with inputs from either
video group (although ties can only be made to the computer/audio subgroup). Adjustable
input audio gain and attenuation compensates for level differences between audio inputs.
The switcher has two RS-232 ports (primary and secondary), and a local area network (LAN)
Ethernet port for remote control and reporting. The matrix switcher is programmed with the
Extron 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 the RS-232 ports or the LAN port.
The LAN port can be connected through a LAN or wide area network (WAN).
The MPX can be operated by any of the following connected to either of the RS-232 ports
or to the LAN port:
