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.
