4X4 QuickMedia™ Matrix
Switcher: QM-MD4X4
Introduction
The QM-MD4X4 is a 4X4 QuickMedia matrix switcher designed to provide versatile
routing of up to four inputs from QuickMedia Wall Plates and FlipTop boxes to any
of four QuickMedia receivers. All signal routing is provided over inexpensive
CAT5e type cable* via Crestron's exclusive QuickMedia transport, supporting the
distribution of high-resolution RGB, video, stereo audio and microphone signals up
to a total of 450 feet end-to-end. Audio breakaway capability allows audio signals to
be routed independent of video signals.
Features and Functions
• Four input by four output QuickMedia matrix switcher
• QuickMedia technology carries high-resolution RGB, video, stereo
audio and microphone signals up to 450 feet using either Crescat-QM-P
or Crescat-QM-NP QuickMedia cable from Crestron®
• Audio breakaway can route audio signals independent of video signals
• Expands number of inputs and outputs of existing QuickMedia systems
• Front panel buttons can be used to operate switcher; buttons can be
custom labeled
• Front panel buttons can be disabled for security
• Control system program can operate the switch via digital, analog, and
serial control
• QuickMedia ports include Cresnet®ports with 24VDC power

Up to two QuickMedia Matrix Switchers and Distribution Centers may be cascaded
in a given QuickMedia signal path* to support larger system configurations. For
instance, a QM-MD4X4 may be used to expand the input capacity of a QM-MD7X2,
or multiple QM Matrixes can be combined to support applications such as room-
combining with numerous inputs and outputs.
* 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.

Complete system operation can be made transparent to the end-user with all signal
routing occurring smoothly under the command of the MediaManager control
system. Control and monitoring of the QM-MD4X4 is also possible independent of
the control system using its front panel pushbuttons and LEDs. Customizable label
strips are provided to easily designate inputs and outputs by name using Crestron
Engraver software or standard 3/8" tape labels. For security, the front panel controls
can be locked out.
Every QuickMedia port on the rear panel is accompanied by a Cresnet port with 24V
DC power distribution built in to simplify termination of the QuickMedia and
Cresnet wiring.
Applications
