Crestron QM-RMCRX-BA
Crestron QM-RMCRX-BA
Room Media Controller and
QuickMedia™ Receiver
Crestron’s MediaManager is a comprehensive family of affordable products fusing
high-performance AV signal distribution, device control, and facility-wide system
management. MediaManager simplifies the art of ProAV system design and
installation with complete hardware, software, and low-cost wiring solutions.
The QM-RMCRX-BA combines a 2-Series Ethernet control system with a
QuickMedia receiver, digital audio processor, and stereo amplifier to provide a
cost-effective solution for AV signal routing and control as part of a complete
MediaManager AV presentation system.
QuickMedia™ Transport—Crestron’s ingenious QuickMedia transport routes all
audio, video, and RGB computer signals over a single inexpensive CAT5e or CAT6
cable*. Computer resolutions up to 1600 X 1200 pixels at 60Hz are supported over
cable runs up to 328 feet. Stereo audio and microphone signals are transmitted
digitally with high-performance 24-bit resolution.
QuickMedia Receiver—Mounted at the projector or plasma display location, the
QM-RMCRX-BA receives the QuickMedia (QM) signal from any QM Transmitter or
Distribution Center, breaking out each media signal to its respective format to feed
the AV inputs on the display device.
High-Res Computer and Video—Separate composite, S-Video, and RGBHV
outputs deliver high-quality video and high-resolution computer graphics to the
display device. Signal routing occurs automatically under the command of the
control system based upon the input source selected at the QM transmitter.
Software-controllable compensation maximizes image quality over long cable runs.
High-Performance Audio—In addition to video and RGB, the QuickMedia transport
carries four channels of 24-bit digital audio comprising a stereo program signal
and two discrete microphone signals. Within the QM-RMCRX-BA, each of the two
incoming microphone signals is processed by its own 4-band speech-optimized
graphic equalizer. Versatile 4X3 mixing allows the mic signals and stereo program
signal to be precisely adjusted and routed any or three audio output channels. The
three channels are ordinarily configured to support discrete stereo program and
mono speech outputs, although any mix of signals is possible.
control system for an entire MediaManager system or as a slave device
communicating with other Crestron components via Cresnet or Ethernet. The
built-in high-speed Ethernet port and Web server provide full connectivity for
remote programming and diagnostics, and seamless integration into control
networks of any size. Native support for Crestron e-Control®2 and RoomView™
applications delivers the industry's best IP-based control and help desk solution.
Best of all, complete MediaManager systems are easy to design, program and
adjust from start to finish using Crestron SystemBuilder™ software.

Processor
The three balanced line-level outputs can be connected directly to inputs on the
display device or used to feed a separate amplifier or external powered speakers. A
built-in 20 watt stereo amplifier is also provided to drive a pair of speakers directly.
CPU: 32-bit Motorola ColdFire® Microprocessor
Professional Digital Audio Processing—Each output channel includes softwareadjustable volume, bass, treble, mute, and versatile 12-band parametric/graphic
equalization. In addition, the speech output includes up to 40mS of delay for ceiling
speaker alignment.
Operating System
With such extensive audio features, the QM-RMCRX-BA effectively eliminates the
need for expensive outboard processors to tailor the system's audio performance
to the acoustical environment. Many parameters are controllable in real-time from a
keypad or touchpanel, and numerous presets can be saved for instant recall to
reconfigure settings for changing room conditions or varying source material.
Display Control Interface—The QM-RMCRX-BA includes two bidirectional RS-232
ports and one IR/Serial port to provide full control of the display device and other
equipment. Two relay ports are also included for control of a projection screen or
lift. In addition, the four digital input ports can accept the direct connection of room
occupancy sensors and power sensors for enhanced automation and monitoring.
2-Series Ethernet Control System—At the heart of the QM-RMCRX-BA is the
powerful 2-Series control engine, which can be configured to serve as the master
