QuickMedia™ Matrix Switcher/Mixer Crestron QM-MD5x1
Functional Summary (continued)
• Auto Compensation automatically recalls microphone EQ settings,
source compensation settings and peak and boost preset values of
multiple QM origination points when acting as an endpoint
• Stores and transmits audio
p
arameters for recall by a QM receiver when
acting as a QM origination point
• Cresnet
®
connector for each QM port simplifies the use of QM cables
• Switching operations can be performed through a Crestron control
system or the MD5x1’s front panel
• Custom-labeled front panel buttons provide local control of switching
functions
• Expandable switching capabilities by connecting to another MD5x1, a
QM-MD7x2, a QM-MD8x8, or a QM-MD4x2 switcher
• Touch-settable ID (TSID) ready
The MD5x1 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 and video input signals can be switched to the QM/line-
level output port. The presence of an MD5x1 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 MD5x1 can be connected to another MD5x1 or other
QM switcher (such as the QM-MD8x8, QM-MD7x2, or QM-MD4x2) to provide
additional switching capabilities.
Switching
Audio and video input signals are independently switched to the output port.
Any of the five video input signals can be switched to the QM output. The five audio
inputs can be switched to the QM output and mixed into the program audio or speech
channels of the local audio output.
Mixing
The MD5x1 has built in mixers for the mixing of microphone and program audio
signals.
Microphone Mixing
The QM input can carry up to two microphone channels from a remote QM
transmitter.
The microphone signals are fed into a microphone mixer while four bands of
equalization are applied to each microphone signal. The output is routed to the
microphone channel of the QM output and the speech and program audio mixers of
the local audio output.
Program Mixing
A mixing stage is provided at the 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.
