QM-MD5X1 - Crestron EU
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
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
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
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
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-MD5X1.
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-MD5X1 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.
