Multimedia Presentation System 300 Crestron MPS-300
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-300 actually affords some additional
hidden flexibility, providing discrete 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 used for
component, S-video, or composite signals; 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.
QuickMedia™ Matrix
In addition to its conventional type video inputs and outputs, the MPS-300
accommodates additional sources and display devices via Crestron's exclusive
QuickMedia (QM) transport. Three QM inputs accept connections from QM Wall
Plates, FlipTop Boxes, and Distribution Centers, providing an abundance of
additional inputs for AV, computer, and microphone sources. Three QM outputs are
also provided, each independently controllable to feed multiple displays and other
devices.
QuickMedia provides a very streamlined, low-cost, long-distance wiring solution.
The 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 full range of QM transmitters, receivers,
and other products is offered by Crestron
* 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.

to suit any application.
Touchpanel Output
Any of the QM outputs may be utilized to feed a preview signal to the system
touchpanel. Additionally, one Crestron Home
is included, its signal corresponding with the first QM output, providing for
simplified wiring to a complete range of Crestron touchpanels. Each 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).

(CH) CAT5 Balanced Video output
8-Channel Microphone Matrix Mixing
Two gated microphone/line inputs are included on the MPS-300 complete with
software-switchable 48V phantom power and independently adjustable compression
and limiting. Up to six additional microphone signals can be brought in through the
three QM inputs, with 4-band speech-optimized equalization provided on all eight
mic channels. Sophisticated matrix mixing allows for six completely different mixes
of all eight microphones—three mixes feeding discrete “local” outputs, and three
multi-threaded; FAT32 file system with long
names; supports SIMPL Windows and

CAT5 Wiring
Category 5 (CAT5) wiring is a twisted pair cable designed for Ethernet networks.
These networks operate at speeds of up to 100 Megabits per second (Mbps) using the
100BaseT standard. Crestron takes advantage of this specification for a variety of
video applications.
Crestron recommends using CresCAT, CresCAT-D or CresCAT-Q wiring solutions.
The following chart shows the maximum recommended cable lengths for various
signal formats.
Recommended Maximum Cable Lengths for Video via Crestron Certified Wire

Component 500 feet
For more information, refer to the latest version of the Crestron CAT5 Wiring
Reference Guide (Doc. 6137).
Crestron MPS-300 Multimedia Presentation System 300
QuickMedia Wiring
The Crestron QuickMedia cable (sold under the name “CresCAT-QM”) contains one
CAT5E cable and one Cresnet cable in Siamese jackets. Installation of any QM
device is as simple as installing CresCAT-QM wires from the output of one device to
the input of another. Installations are flexible, affordable and fast. For more
information, refer to the latest revision of the Crestron MediaManager Applications
Guide (Doc. 6244).
CresCAT-QM Cable
NOTE: Do not untwist the two wires in a single pair for more than 1/3-1/2”
(0.84-1.27 cm) when making a connection. The twists are critical to canceling out
interference between the wires.
The aggregate cable length of a signal path originating at the MPS-300 and
terminating at a QM receiver must not exceed 450 feet (137 meters). Video signals
may experience a loss of quality over very long lengths of cable. This phenomenon is
due to the added resistance and capacitance of longer cable lengths and is not
peculiar to either Crestron and/or QuickMedia systems. To ensure sufficient
bandwidth, the maximum aggregate cable length should not exceed 450 feet. The use
of lower-resolution signals may allow increased cable length but must be tested by
the installer with the sources to be used. The QM pin assignment is based on the
EIA/TIA 568B RJ-45 Jack standard.
NOTE: When transmitting S-video, luminance uses the green video pathway and
chrominance uses the red video pathway. When transmitting composite video, the
signal is carried on the blue video pathway.
NOTE: When using CresCAT-QM wiring, four additional wires are included for
making Cresnet connections.
When connecting multiple QM devices, the route between a QM origination point
(transmitter) and a QM endpoint (receiver) cannot have more than two midpoints
(e.g. QM-MD7x2 or other QM switchers). Refer to the following diagram when
configuring a QM network.
NOTE: Use CresCAT-QM to make QM connections. The cumulative skew over the
entire length must be less than 22 ns.

Installation
The MPS-300 should be used in a well-ventilated area. The venting holes should not
be obstructed under any circumstances. If the MPS-300 is hot to the touch, consider
using forced air ventilation and/or incrementing the spacing between units.
To prevent overheating, do not operate this product in an area that exceeds the
environmental temperature range listed in the table of specifications. Consideration
must be given if installed in a closed or multi-unit rack assembly since the operating
ambient temperature of the rack environment may be greater than the room ambient
temperature. Contact with thermal insulating materials should be avoided on all sides
of the unit.
The MPS-300 can be mounted in a rack or stacked with other equipment. Two
“ears” are provided with the MPS-300 so that the unit can be rack mounted. These
ears must be installed prior to mounting. Complete the following procedure to attach
the ears to the unit. The only tool required is a #2 Phillips screwdriver.
WARNING: To prevent bodily injury when mounting or servicing this unit in a
rack, take special precautions to ensure that the system remains stable. The following
guidelines are provided to ensure your safety:
•When mounting this unit in a partially filled rack, load the rack from the
bottom to the top with the heaviest component at the bottom of the rack.
•If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
NOTE: Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct
connections to the branch circuit (e.g. use of power strips).
To install the ears:
1. There are screws that secure each side of the MPS-300 top cover. Using a
#2 Phillips screwdriver, remove the three screws closest to the front panel
from one side of the unit. Refer to the diagram following step 3 for a
detailed view.
2. Position a rack ear so that its mounting holes align with the holes vacated
