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.

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.
