Multimedia Presentation System 250
Crestron
MPS-250
System Switcher
Right out of the box, the MPS-250 provides high-performance switching of two
video and three RGB computer sources to a single projector or plasma 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;
o
utput 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.
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.
Crestron’s 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*. 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.
*
For QuickMedia wiring use CresCAT-QM-P, CresCAT-QM-NP, CresCAT-IM-P, or quality
CAT5e/CAT6 cable with a delay skew of
≤
15ns per 100m; the maximum aggregate cable length and
delay skew between any QM transmitter (origination point) and QM receiver (endpoint) is 450 ft
(137 m) and 22 ns; a maximum of two QM midpoint devices may be inserted in a given QM signal
path; exceptions apply, refer to each respective product manual for full detail.
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 speech-optimized equalization provided on all four mic channels.
Sophisticated matrix mixing allows for four completely different mixes of all four
microphones – three mixes feeding discrete “local” outputs, and one additional mix
feeding the QM output.
