Crestron Electronics, Inc. - QM-AE4

Crestron 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. Whether installing a single boardroom or a campus-wide network of AV systems, MediaManager delivers power and value far beyond conventional products and designs. The QM-AE4 is a single-space rack mount unit containing the equivalent of four QM-AE1 QuickMedia Audio Extractors. Its four independent extractors provide the ability to extract the stereo program and microphone audio signals from four separate QuickMedia feeds to drive a power amplifier or other audio device. Each QM Audio Extractor may be inserted anywhere along the QM signal path without affecting the audio, video, and computer signals passing through it. For ultimate flexibility, any of the QM-AE4's extractors may operate as a QM endpoint, effectively functioning as a QM audio receiver. The revolutionary QuickMedia transport routes all audio, video, and RGB computer signals over a single inexpensive CAT5e type cable. Stereo audio and microphone signals are transmitted digitally over QuickMedia with high-performance 24-bit resolution. The QuickMedia transport carries four channels of 24-bit digital audio comprising a stereo program signal and two discrete microphone signals. Within any of the QM-AE4's four audio extractors, the two incoming microphone signals are each processed separately by a 4-band speech-optimized graphic equalizer. Versatile 4x4 matrix mixing allows the mic signals and stereo program signal to be precisely adjusted and routed to any of four audio outputs. These outputs are configured as one stereo program channel and two discrete mono speech channels, perfect for feeding a Crestron QM-Series 3-channel amplifier along with other recording and assistive listening equipment. All outputs are balanced line-level for proper integration with professional and semi-pro gear. The QM-AE4 lets you control and optimize your system's audio performance without the need for additional outboard processors. Each output channel includes programmable volume, bass, treble, and mute, plus ten-band graphic equalization and 2-band parametric equalization. In addition, each speech output includes up to 40 ms of delay adjustment for proper ceiling speaker alignment. All audio processing and mixing is performed in the digital domain, adjustable at setup using Crestron QM Tools software. The QM-AE4 affords seamless audio signal routing and control under the command of a MediaManager control system. Many parameters are controllable in real-time from a keypad or touchpanel, and numerous presets can be saved for instant recall. A complete MediaManager system is easy to design, program and adjust from start to finish using Crestron SystemBuilder software.
