The MPS-250 is a complete presentation control and signal routing solution for
boardrooms and classrooms. Integrating the control system, multimedia matrix
switcher, mic mixer, audio processor, amplifier, and QuickMedia distribution center
all into a single 2-space rackmount package, the MPS-250 affords considerable
signal routing versatility and high-performance signal processing without the need
for separate components.

System Switcher—Right out of the box, the MPS-250 provides high-performance
switching of 2 video and 3 RGB computer sources to a single projector or flat­panel display. Composite, S-Video, component and RGBHV signals can be routed
to the appropriate inputs on the display device, with control of the display
provided via Ethernet, RS-232 or IR. Input signal sensing is provided on every
video and RGB input to enable auto-switching functionality and provide device
power status information to the control system. Selectable sync impedance on the
RGB inputs helps accommodate cable runs of varying lengths.

Versatile matrix switching inside the MPS-250 actually affords some additional
hidden signal routing flexibility, providing discrete switchable outputs for RGB,
composite, S-Video, and component signals. For instance, Outputs 1 and 2 can
function as separate composite and S-Video outputs, or as a single component
output; Output 3 can be a single component, S-Video, or composite output; and
Output 4 can be used for either RGB or component. Each output is fed by a
separate matrix crosspoint, so they all can be active simultaneously and assigned
any relevant input source.

NEW! RGB Pass-thru mode provides a quick path to integration with the ground­breaking Crestron DigitalMedia™ system. With just a single 15-pin VGA cable
connected to a DM-MD6X1 DigitalMedia switcher, DMC-DVI input card, or any
other DM product with an RGB input, the MPS-250 automatically routes whatever
video signal is selected – whether RGB, component, S-Video, or composite –
allowing seamless conversion to digital for distribution to HDTV displays and
projectors throughout your facility.

Touchpanel Output—An additional discrete output is provided on the MPS-250 to
feed a preview signal to the system touchpanel or other monitor. This output is
controlled separately from the main display outputs, allowing a different source to

be viewed on the touchpanel. The touchpanel connection is facilitated through a
choice of QuickMedia

®

(QM) or Crestron Home®(CH) CAT5 Balanced Video
outputs, simplifying wiring to a wide range of Crestron touchpanels. The QM
output supports high-resolution RGB and HDTV plus audio, while the CH output is
limited to standard video and HDTV only (dependent upon the capabilities of
the touchpanel).

QuickMedia

®

—The QM Touchpanel output can also be used to feed signals

straight to the primary display device, providing a very streamlined, low-cost,
long-distance wiring solution. The Crestron exclusive QuickMedia transport
transmits high-resolution RGB, HD video, stereo program and microphone audio
signals up to 450 feet over a single inexpensive CAT5e type cable

[1]

. Just one
CresCAT-QM cable and a QM receiver are all that is required for complete signal
routing and device control, eliminating all the bulky, expensive cabling that would
otherwise be needed.

A single QM input is also provided on the MPS-250, providing additional inputs
for AV, computer, and microphone sources through the simple connection of a
QM Wall Plate, FlipTop Box, or Distribution Center.

4-Channel Microphone Matrix Mixing—Two gated microphone/line inputs are
included on the MPS-250 complete with software-switchable 48V phantom power
and independently adjustable compression and limiting. Two additional
microphone signals can be brought in through the QM input, with 4-band speech­optimized equalization provided on all 4 mic channels. Sophisticated matrix
mixing allows for four completely different mixes of all 4 microphones—three
mixes feeding local Program, Speech, and Record outputs, and one additional mix
feeding the QM output.

Professional Audio Features—Five stereo audio inputs on the rear panel accept
balanced or unbalanced line-level signals from computers and other program
audio sources. Additional audio sources can be brought in through the QM input.
To accommodate a wide range of signals, adjustable input compensation is
employed to help maintain consistent volume levels when switching between
sources. Versatile matrix mixing allows the selected program signal and the 4
microphone signals to be separated or mixed in any combination to feed 3 local
audio outputs, each with its own unique mix.

Three “local” balanced line level outputs are provided on the MPS-250, each with
independent adjustments for volume, bass, treble, and mute. The stereo
PROGRAM and mono SPEECH outputs are normally intended for driving external
amplification, with relay muting on each output to prevent “thumping” on power
up. The RECORD output allows for a separate stereo mix to feed a recording
device or assistive listening system. Ten-band graphic equalization plus 2-band
parametric equalization on each output eliminates the need for expensive outboard
audio processors, and up to 40mS delay adjustment is available on the SPEECH
output for proper loudspeaker alignment.

The QM Touchpanel output is controlled separately from the other audio outputs,
allowing a different program source and microphone mix to be monitored on the
touchpanel, or output to other audio equipment by way of an appropriate QM
receiver or other QuickMedia device.

Built-in Amplifier—A 40-watt amplifier is built into the MPS-250, with three
models available offering the choice of 8-ohm stereo, 70V mono, or 100V mono
outputs. For large rooms requiring more power, the MPS-250 supports plug-and­play compatibility with Crestron QM-Series 3-channel amplifiers, providing a
complete solution for driving a professional loudspeaker system with separate
program and speech channels.

Front Panel Control—Out of the box, the MPS-250 front panel supports easy
pushbutton routing of input sources to each of the outputs, and audio volume
adjustment using the volume control knob. Dedicated buttons and indicators are

also provided for separate control of system power and projector power. In
addition, five preset buttons are included for custom functions such as lowering
a projection screen, closing blinds, or selecting a lighting preset.

The front panel label strips are easily customized using Crestron Engraver
software or standard 3/8” tape labels, allowing for the clear designation of each
input, output, and preset button. When selected, these functions will also appear
on the LCD display as generic names (Input 1, 2…), or as custom names (DVD,
Podium PC, Screen Up, etc.).

Easy setup of the MPS-250 is facilitated through the LCD display without
necessitating a computer. Together with 4 softkey buttons, 4 menu navigation
buttons and the volume knob, the LCD enables configuration of IP network,
audio, and other system settings. For security, the front panel controls can be
password protected or locked out.

2-Series Control System—Integrated into the MPS-250 is a Crestron 2-Series
Ethernet control system complete with e-Control

®

2 Web server and a host of
RS-232, IR, digital input and relay control ports for integration with third-party
equipment. Anything from a basic AV presentation room with a single projector,
screen, and keypad controller, to a fully custom touchpanel based system with
multiple controlled sources and display devices, can be programmed easily
using Crestron SystemBuilder™ software. And, the MPS-250 works with
Crestron RoomView

®

Help Desk software, the industry's most comprehensive

facility-wide asset management solution.

Room Control Options—Without requiring any programming, the MPS-250 can
be controlled simply using a Crestron APAD LCD Controller or a selection of
keypads. With custom programming, our complete line of Isys™ touchpanels
and MediaManager FlipTops is supported. Equipped with an optional
CNXRMIRD IR receiver, the MPS-250 allows any Crestron IR wireless touch­panel or handheld remote to be used for a low-cost wireless control solution. Or,
adding an RF wireless gateway or Wi-Fi access point enables use of a wide
range of 1-way and 2-way RF wireless handheld remotes and touchpanels.
