Introduction Introduction
The QM-MD8X8 is an 8X8 QuickMedia matrix switcher designed to provide
versatile routing of up to eight inputs from QuickMedia Wall Plates and FlipTop
Boxes to any of eight 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
• Eight input by eight output QuickMedia matrix switcher
• QuickMedia technology carries high-resolution RGB, video, stereo
audio and microphone signals up to 450 feet using CresCAT-QM-P,
CresCAT-QM-NP, or CresCAT-IM-P 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
distribution to simplify termination of QuickMedia and Cresnet wiring
• Single-space rack-mountable
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-MD8X8 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.
