QM-RMCRX-BA - Hills Industries Ltd

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 type cable*.
Computer resolutions up to 1920 X 1200 pixels at 60Hz are supported
over cable runs up to 450 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 to any of 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.
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.
Professional Digital Audio Processing
Each output channel includes software-adjustable volume, bass, treble,
and mute, plus ten-band graphic equalization and 2-band parametric
equalization. In addition, the speech output includes up to 40mS of
delay adjustment for proper ceiling speaker alignment. All audio
processing and mixing is performed in the digital domain, adjustable
at setup using Crestron's QM Tools software (part of Crestron
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 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.
