QuickMedia® Transmitter Computer Center (QM-TX2-CC)
The QM-TX2-CC affords a portable or rack mounted computer interface solution for
QuickMedia (QM) based MediaManager systems. The QM-TX2-CC can be used in
a variety of applications to send computer signals to one or more displays using
Crestron’s exclusive single-wire QuickMedia transport.
QuickMedia Transmitter Media Center (QM-TX2-MC)
The QM-TX2-MC affords a portable or rack mounted multimedia interface solution
for QuickMedia based MediaManager systems. The QM-TX2-MC can be used in a
variety of applications to send audio, video and computer signals to one or more
displays and audio amplifiers using Crestron’s exclusive single-wire QuickMedia
transport.
Dual Computer Interface (QM-TX2-CC)
The QM-TX2-CC is ideal for installation in a presentation podium, computer station
or central equipment rack to transmit computer signals to a QM receiver or
distribution center using just a single inexpensive CresCAT™QM cable. It is also
perfect for portable use, requiring just one RJ-45 plus a 4-pin Cresnet® connection in
any standard wall plate or floor box to provide an extremely simple yet versatile
computer input anywhere in the room. Since it is powered by Cresnet, it does not
even require a connection to AC power.
Two independent DB15HD computer inputs are provided on the QM-TX2-CC, each
with corresponding stereo audio, to accept connections from two separate computer
sources. Both inputs support RGBHV signals up to WUXGA 1920 x 1200. Buffered
monitor pass-through connectors are also included to feed the input signals to local
monitors.
Versatile Multimedia Interface (QM-TX2-MC)
Installed in a central equipment rack, the QM-TX2-MC is idea for converting the
output of a conventional AV source or switcher to QuickMedia for transmission to a
QM receiver or distribution center using just a single inexpensive CrestCAT-QM
cable. It is also perfect for portable use, requiring just one RJ-45 plus a 4-pin Cresnet
connection in any standard wall plate or floor box to provide an extremely simple yet
versatile AV or computer input anywhere in the room. Since it is powered by
Cresnet, it does not even require a connection to AC power.
Individual video and RGB inputs are provided, each with corresponding stereo
audio, to accept connections from separate AV and computer sources. The multiformat BNC video input supports composite, S-video and component formats
including 1080p HDTV. The DB15HD computer input supports RGBHV signals up
to WUXGA 1920 x 1200. A buffered monitor pass-through connector is also
included to feed the RGB input signal to a local monitor.
Professional Balanced Audio
Two balanced stereo line level audio inputs are provided. Audio breakaway
capability allows the audio inputs to be switched independent of the video
(QM-TX2-MC only) and RGB inputs or linked with them.

Crestron QM-TX2-CC & QM-TX2-MC Transmitter Computer & Media Centers
Built-in 2x1 Switcher
All video (QM-TX2-MC only), RGB and audio signal switching is performed
onboard the QM-TX2-CC/MC. Switching can be controlled programmatically from
any remote keypad or touchpanel or right from the front panel. Built-in signal
sensing on each video/RGB input can be utilized to trigger automatic input selection,
as well as other system functions such as device power control.
IR Control Port
A single IR output port is included in the QM-TX2-CC/MC to enable programmable
control of a multimedia computer (for QM-TX2-CC), a local DVD player (for
QM-TX2-MC) or other IR-controllable device.
QuickMedia Transport
Using Creston’s revolutionary QuickMedia transport, the selected input signals are
transmitted from the QM-TX2-CC/MC to any QuickMedia receiver or distribution
center over a single inexpensive CAT5e type cable*. Computer resolutions up to
1920 x 1200 pixels at 60 Hz are supported over cable runs up to 450 feet (137
meters). Audio signals are transmitted digitally with high performance 24-bit
resolution. QuickMedia dramatically simplifies system design and installation,
affording a higher level of performance at a lower overall cost.
* For QuickMedia wiring, use CresCAT-QM, CresCAT-IM or quality CAT5e/CAT6 cable with a delay
skew of ≤ 15 ns per 100 meters; the maximum aggregate cable length and delay skew between any
QM transmitter (origination point) and QM receiver (endpoint) is 450 feet (137 meters) 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 details.
MediaManager System Integration
Whether using just one QM transmitter or several, 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. Complete MediaManager systems
are easy to design, program and adjust from start to finish using Crestron®
SystemBuilder™ software.
EDID Format Management
The QM-TX2-CC/MC allows for management of the EDID (Extended Display
Identification Data) information sent to the connected source. Using Crestron
Toolbox™ software, the format and resolution capabilities of each device can be
assessed and managed through the QM-TX2-CC/MC, ensuring reliable operation by
instructing sources to output only the resolutions and formats that can be handled by the
displays and system wiring.
