MPX 423 A
n
Bandwidth – The MPX 423 A provides a minimum of 350 MHz (-3dB)
RGB video bandwidth for high resolution computer-video sources,
and 150 MHz (-3dB) of video bandwidth for composite-video and
S-video sources. This maintains signal integrity and ensures switching
and distribution of video signals without degradation.
n Single Switcher mode – Allows one-touch switching. When one of
the 12 inputs is accessed, the signals of the input will be routed to
the outputs of its group. Outputs of the other groups are muted,
while audio output is restricted to its own group.
n Separate Switcher mode – Allows independent switching to the
output of any given I/O group. This effectively divides the
MPX 423 A into three separate switchers.
n RGB Mute – Allows the user to mute the video outputs, all at once
or individually. The image is muted by removing the RGB signals,
while leaving the sync signals active, allowing the image to be
restored without any visible glitch or distortion.
n Video genlock (for composite and S-video) – Allows for vertical
interval switching and enables smooth, seamless transitions when
switching between synchronous video sources.
n Digital Sync Validation Processing (DSVP
™
) – Extron’s exclusive
DSVP verifies active sources by displaying horizontal and vertical scan
rate information. This allows the monitoring of input signal status
information, as well as the scan rate for the computer signal inputs.
n Audio input gain and attenuation – Allows users to set the level
of gain or attenuation for each audio input channel, eliminating
noticeable differences when switching between sources.
n Speed-sensitive volume control – Audio volume can be adjusted
in 0.5 db or 2.5 dB increments, depending on how fast the volume
adjustment knob is turned. This automatic sensitivity control allows
the user to easily fine-tune the audio volume.
n Audio breakaway – Provides the capability to break an audio
signal away from its corresponding video signal, allowing the audio
channels to be operated as a separate matrix switcher.
n RS-232 control – Using RS-232 serial commands, the MPX 423 A
can be controlled and configured via the Extron Windows
®
-based
control program, or integrated into third-party control systems.
Extron products use the Simple Instruction Set (SIS
™
) command
protocol, a set of basic ASCII code commands that allow for quick
and easy programming.
n IP Link
™
– Specifically engineered to meet the needs of
professional A/V environments, IP Link-enabled products offer an
integrated Web server with high performance architecture, global
compatibility with industry standard Ethernet communication
protocols, multi-user support, and a Web-based asset management
application specifically designed to work with products that
include IP Link technology.
n Front panel security lockout – Prevents unauthorized use when
the matrix switcher is installed in an unsecured environment where
easy access is not desirable. In lock-out mode, a special button
combination is required to operate the front panel.
n Internal international power supply – The autoswitchable,
internal power supply provides worldwide power compatibility.
The Extron MPX 423 A Media Presentation Matrix Switcher is a
cost-effective solution for expanding projector input capabilities,
while providing an additional output for a second display used in a
presentation or for preview monitoring. This compact, integrator-
friendly matrix switcher is ideal for a variety of small-scale applications
including classrooms, training and conference facilities, and
sophisticated home theaters.
When switching the inputs of the MPX 423 A, the user can choose
between the Single Switcher mode and Separate Switcher mode.
Single Switcher mode turns the MPX 423 A into a single 12 input
switcher that routes the signals of the input to the outputs of its
group. Outputs of the other groups are muted, while the audio
output is restricted to its own group. This is especially useful for
feeding projectors or plasmas with auto switching capability.
In Separate Switcher mode, the MPX 423 A effectively becomes
three switchers, enabling independent switching to the output
of any given I/O group. The MPX 423 A also offers a 12x2 audio
switcher that can access the audio of all three video groups.
Balanced and unbalanced audio inputs and outputs are provided on
convenient captive screw connectors.
Control of the MPX 423 A is provided via the front panel, RS-232,
or IP Link
™
ethernet control. Housed in a 1U, full rack width metal
enclosure, the MPX 423 A can be easily mounted into any rack or
podium, or under a desk.
