Crestron QM-MD4x2 QuickMedia Distribution System
QuickMedia Distribution System:
QM-MD4x2
Introduction
Features and Functions
The Crestron®QuickMedia Distribution System, QM-MD4x2 (hereinafter referred to
as MD4x2) is part of the Crestron MediaManager™ line of network devices, room
control systems, and signal routing solutions.
Functional Summary
• Four input by two output matrix switching of composite video,
S-video, RGB, and audio signals
• Switching scheme allows one QuickMedia (also known as QM) input
to be switched to one, or both of the available QM outputs
• Separate switching of audio and video portions of QM input signals
• Four QuickMedia inputs (RJ-45) for connection to QM wall plates
and/or QM FlipTop media centers
• Two QM outputs (RJ-45) for connection to QM receivers
• Cresnet connector for each QM port simplifies the use of QM cables
• Dedicated power connections allow for sufficient power distribution
among connected components
• Switching operations can be performed through a Crestron control
system or the QM-MD4x2’s front panel
• Custom-labeled front panel buttons provide local control of switching
functions
• Expandable switching capabilities by cascading with other MD devices
• Touch-settable ID (TSID) ready
The MD4x2 is a QuickMedia™ (also known as QM) signal routing device used for
the switching and routing of multiple QM signals within a QM system. The audio
and video portion of each QM input signal can be separately switched to either of
two QM output ports. The presence of an MD4x2 in a system does not improve or
degrade QM signal quality, nor does it increase or decrease the length of QM cable
that can be used in a cable run. An MD4x2 can be cascaded with a second MD4x2 or
other QM-MD switching device to provide additional switching capacity.

QuickMedia Distribution System Crestron QM-MD4x2
Applications
The MD4x2 is part of the Crestron MediaManager line of integrated presentation
solutions. It is ideally suited to work with Crestron’s MediaManager wall plate
media centers, FlipTop media centers, receivers and control processors to allow
quick switching of multiple A/V sources in a presentation system. MediaManager
devices are designed for conference room, auditorium, and lecture hall applications,
or anywhere else audio, video, or computer equipment needs to be easily connected
and disconnected from a presentation system or room control system.
The following diagram shows an MD4x2 in a lecture hall application.

For more information on this and other QM applications, refer to the latest revision
of the Crestron MediaManager Control, Switching and Management Applications
Guide (Doc. 6244) which can be downloaded from the Downloads | Product Manuals
section of the Crestron website (www.crestron.com).
The following diagram represents the switching abilities of the MD4x2. The MD4x2
can be operated locally (local mode) using buttons on the front panel, or remotely
from a control system (system mode). For more information, refer to “Operating
Modes” on page 28.

FTP site).
Physical Description
The MD4x2 is housed in a black enclosure with labeling on the front and rear panels.
Twelve buttons with accompanying light emitting diodes (LEDs) on the front panel
are used for local control of source and destination signal switching. The source and
destination selection buttons can be custom-labeled with Crestron Engraver software
and 100-pound paper. Two LEDs on the front panel indicate power and network
activity. All QM, Cresnet®, and power connections are made to the back of the unit.
A pushbutton on the rear panel with an accompanying LED is used to set the
MD4x2’s network ID. Refer to the following illustrations of the front and rear panels
and the physical views.
Two mounting ears are provided for rack mounting, and four square rubber feet are
supplied for stability and to prevent slippage in tabletop placement or stacking
configurations.

The MD4x2 contains four QM ports for connecting QM sources. Each QM port has
an RJ-45 connector for QM signals and a corresponding 4-position mini-terminal
block connector for Cresnet control signals.
For wiring information, refer to “QuickMedia Wiring” on page 10 and “Network
Wiring” on page 9.
The 4-position mini-terminal block connector on each QM IN port receives 24 VDC
power from a 2-position terminal block connector for proper power distribution to the
attached QM devices. For information on connecting 24 VDC power to the QM IN
ports, refer to “Hardware Hookup” on page 16.

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: Use Crescat-QM, or good quality CAT5E / CAT6 cable to make QM
connections. The cumulative skew over the entire length must be less than 15 ns.
Refer to “QuickMedia Wiring” on page 10 for cable specifications.
NOTE: When using Crescat-QM wiring, four additional wires are included for
making Cresnet connections. Refer to “QuickMedia Wiring” on page 10 for cable
specifications.
QM OUT
G24 Y Z
The MD4x2 contains two QM ports for connecting QM receivers or any other device
with a QM input. Each QM port has an RJ-45 connector for QM signals and a
corresponding 4-position mini-terminal block connector for Cresnet control signals.
For wiring information, refer to “QuickMedia Wiring” on page 10 and “Network
Wiring” on page 9.
The QM pin assignments for the QM OUT ports are the same as the QM IN ports
described previously.
The 4-position mini-terminal block connector on each QM OUT port receives 24
VDC power from a 2-position terminal block connector for proper power distribution
to the attached QM devices. For information on connecting 24 VDC power to the
QM port groups, refer to “Hardware Hookup” on page 16.
