Crestron QM-MD7x2 QuickMedia™ Matrix Switcher/Mixer
QuickMedia™ Matrix
Switcher/Mixer: QM-MD7x2
Introduction
Features and Functions
The Crestron®QuickMedia Matrix Switcher/Mixer, QM-MD7x2 (hereinafter
referred to as MD7x2) is part of the Crestron MediaManager™ line of network
devices, room control systems, and signal routing solutions.
Functional Summary
• Multimedia switcher/mixer with video, audio, microphone, RGB, and
QuickMedia inputs
• Three composite/S-video/component video (nine BNC connectors)
inputs and two RGBHV (15-pin) inputs with built-in sync sensing
• One RGBHV monitor pass-through connector
• Two QuickMedia input ports can receive RGB, S-video, composite
video, and multi-channel audio signals from another QM switcher or
QM FlipTop/Wall Plate transmitters.
• Two QuickMedia™ output ports for connection to QM receivers or
other QM switchers
• Seven analog audio inputs: Two gated Mic inputs with switchable
phantom power, and five unbalanced stereo audio inputs
• Two 4-channel MIC mixers mix local and QM microphone signals with
electronically adjustable 4-band graphic equalization for output to
respective audio mixers and QM outputs
• Two sets of line-level, balanced/unbalanced, local audio outputs
consisting of a stereo program channel and a mono speech channel that
follows the respective QM output (Audio Output 1 same as QM Output
1)
• Mixer on each local audio output allows independent mixing of left
program, right program, and microphones for each local output channel
• Local audio outputs feature electronically adjustable volume, bass,
treble, mute and 12-band parametric/graphic equalizer
• Separate switching of audio and video portions of each input signal
(continued on next page)

QuickMedia™ Matrix Switcher/Mixer Crestron QM-MD7x2
Functional Summary(continued)
• Cresnet connector for each QM port simplifies the use of QM cables
• Switching operations can be performed through a Crestron control
system or the QM-MD7x2’s front panel
• Custom-labeled front panel buttons provide local control of switching
functions
• Expandable switching capabilities by connecting to other MD7x2s,
QM-MD8x8s, or QM-MD4x2 switchers
• Touch-settable ID (TSID) ready
The MD7x2 is a QuickMedia™ (also known as QM) signal routing device used for
the mixing, switching, and routing of audio, video, microphone, and QM signals
within a QM system. Audio, video, and microphone input signals can be separately
switched to either of the two QM/line-level output ports. The presence of an MD7x2
in a system does not necessarily improve or degrade QM signal quality, nor does it
increase or decrease the length of QM cable that can be used. An MD7x2 can be
connected to additional MD7x2s or other QM switchers (such as the QM-MD8x8 or
QM-MD4x2) to provide additional switching capabilities.
Switching
Audio and video input signals are independently switched to the output ports. Both
QM outputs can be driven simultaneously and independently.
Any of the seven video input signals can be switched to either of the two QM
outputs. The seven audio inputs can be switched to either or both of the QM outputs
and mixed into the program audio or speech channels of the local audio outputs.
The microphone signals from the local microphone inputs and the two QM inputs
can be individually switched to the speech channel of either QM/Audio output.
Mixing
The MD 7x2 has built in mixers for the mixing of microphone and program audio
signals.
Microphone Mixing
Each of the QM inputs can carry up to two microphone channels from a remote QM
transmitter. Additionally, there are two local microphone inputs on the MD7x2 that
can receive microphone-level or line-level microphone signals.
All of the microphone signals are fed into two microphone mixers while four bands
of equalization are applied to each microphone. The output of each mixer is routed to
the microphone channel of the corresponding QM output (mic mixer 1 to QM output
1) and the speech and program audio mixers of the corresponding local audio output
(mic mixer 1 to local audio output 1).
Program Mixing
A mixing stage is provided at each line-level output. The microphone mix described
previously, and the selected audio input is fed to this mixer. The mixer mixes the
program audio and the microphone signal into two outputs, program (stereo) and
speech (monaural). The microphone mix can be mixed into the stereo program and
the stereo program can be mixed into the speech. After mixing, volume, equalization
and tone control can be applied.

The following diagram represents the switching and mixing capabilities of the
MD7x2. The MD7x2 can be operated locally (local mode) using buttons on the front
panel, or remotely from a control system (system mode). For more information, refer

An MD7x2 can also be connected to no more than two MD7x2s, two QM-MD8x8
switchers, two QM-MD4x2s switchers, or any combination of QM switching
devices. This provides additional inputs for one MD7x2 as shown in the following
diagrams.
QM-MD7x2 Connected with Other QM-Switching Devices
When connecting multiple QM devices, the route between a QM origination point
(e.g. QM-WMC) and a QM endpoint (e.g. QM-RMCRX) cannot have more than two
midpoints (e.g. MD7x2 or other QM switchers). Refer to the following diagram
when configuring a QM network.

Applications
The MD7x2 is part of the Crestron MediaManager line of integrated presentation
solutions. It is ideally suited to work with Crestron’s MediaManager distribution
systems, wall plate media centers, FlipTop media centers, receivers and control
processors to allow quick switching of multiple A/V sources in a presentation
system. MediaManager devices are designed for conference room, auditorium, and
lecture hall applications, or anywhere else where audio, video, or computer
equipment needs to be easily connected and disconnected from a presentation system
or room control system.
The following diagram shows an MD7x2 in a lectern application.
