5x1 QuickMedia® Distribution Center

The QM-MD5X1 is a professional AV switcher and digital audio signal processor featuring a QuickMedia input and output plus four sets of local AV inputs and one set of discrete program and speech audio outputs. Occupying just one rack space, the QM-MD5X1 provides versatile signal routing and processing capability as a midpoint distribution switcher or front-end multimedia interface for a complete MediaManager AV presentation system. Two sets of 3 BNC connectors are provided on the QM-MD5X1 to accept video inputs from two composite, S-Video, component, or HDTV sources. Two RGB inputs are also included to accept high-resolution computer sources up to 1920 X 1200 pixels. Four stereo audio inputs accommodate unbalanced line-level signals from computers and program audio sources. In addition to the local inputs, there is a single QuickMedia (QM) input port which receives RGB, video, program audio and mic signals from a FlipTop or Wall Plate transmitter over inexpensive CAT5e type cable* via Crestron's exclusive QuickMedia transport. The 5X1 video and audio switchers built into the QM-MD5X1 allow any of the local or QM input signals to be routed to a single QM output. Independent 4-band speech-optimized graphic equalization is provided for each of two microphone signals brought in at the QM input. A 2X1 mic mixer combines the processed mic signals prior to feeding the QM output. In addition to the QM Output, the QM-MD5X1 also provides 3 local audio outputs consisting of a stereo program channel and a mono speech channel. These balanced/unbalanced line-level outputs are designed to drive rack-mounted amplifiers like the QM-AMP3X80, as well as codecs, recorders, assistive listening devices, and more. Generally, these outputs contain the same stereo program signal and microphone mix as those fed to the QM Output, with the added ability to adjust the mix of left program, right program, and microphone signals independently for each local output channel. Each local output channel includes adjustments for volume, bass, and treble, a mute control, plus ten-band graphic equalization and 2-band parametric equalization. In addition, the speech output includes up to 40mS of delay adjustment for loudspeaker alignment. With such extensive control over the system's audio performance, the QM-MD5X1 effectively eliminates the need for expensive outboard processors to attain precise adjustment tailored to the acoustical environment. All audio processing and mixing is performed in the digital domain, adjustable at setup using Crestron's QM Tools software (part of Crestron Toolbox). Many parameters are also controllable in real-time from a keypad or touchpanel, with numerous presets that can be saved for instant recall to account for varying source material or room conditions.
