7x2 QuickMedia® Distribution Center
The QM-MD7X2 is a versatile matrix switcher and multi-channel digital
audio signal processor featuring two QuickMedia® inputs and outputs
plus five sets of local AV inputs, gated microphone mixing, and two
audio outputs sections each with discrete program and speech channels.
Occupying just one rack space, the QM-MD7X2 affords extensive signal
routing and processing capability as a midpoint distribution switcher
or front-end multimedia interface for a complete MediaManager AV
presentation system.
Three sets of 3 BNC connectors are provided on the QM-MD7X2 to accept
video inputs from three 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. Five stereo audio inputs
accommodate unbalanced line-level signals from computers and program
audio sources.
In addition to the local inputs, there are two QuickMedia (QM) input
ports which receive RGB, video, program audio and mic signals from
FlipTop or Wall Plate transmitters over inexpensive CAT5e type cable*
via Crestron's exclusive QuickMedia transport.
The 7X2 video and audio switchers built into the QM-MD7X2 allow any of
the local or QM input signals to be routed independently to either of
two QM outputs. Each QM output can be used to feed a separate
QuickMedia Receiver to support two independent display devices.
Additionally, two gated microphone inputs are included on the QM-MD7X2
with software switchable 48V phantom power at both inputs to support
either dynamic or condenser microphones. Balanced or unbalanced
line-level sources such as wireless microphones can also be
accommodated. These two microphone/line inputs can be mixed with the
two mic signals brought in at either QM input, with two independent
4X1 mixes possible to feed each of the two QM outputs. Each mix also
includes independent 4-band speech-optimized graphic equalization for
each individual microphone input.
Also key to the QM-MD7X2 is its two sets of local audio outputs, each
consisting of a stereo program channel and a mono speech channel.
These six 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, Audio
Output 1 contains the same stereo program signal and microphone mix as
that fed to QM Output 1, and likewise for Output 2. However, the mix
of left program, right program, and microphones is independently
adjustable 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 outputs include up to
40mS of delay adjustment for loudspeaker alignment.
With such extensive control over the system's audio performance, the
QM-MD7X2 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.
To gain additional signal routing flexibility and expand input and
output capacity, up to two QuickMedia Distribution Centers,
Distribution Amplifiers, and Matrix Switchers may be cascaded in a
given QuickMedia signal path*. For instance, a QM-MD8X8 or QM-MD4X2
may be used to expand the input capacity of the QM-MD7X2. Complete
system operation can be made transparent to the end-user with all
signal routing occurring smoothly under the command of the
MediaManager control system. Built-in video-sensing on every input can
be utilized to trigger automatic input selection and provide power
status information to the control system.
Control and monitoring of the QM-MD7X2 is also possible independent of
the control system using its front panel pushbuttons and LEDs.
Customizable label strips are provided to easily designate inputs and
outputs by name using Crestron Engraver software or standard 3/8" tape
labels. For security, the front panel controls can be locked out.
