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.

Network Wiring
CAUTION: Provide sufficient power to the system. Insufficient power can lead to
unpredictable results or damage to the equipment. Please use the Crestron Power
Calculator (http://www.crestron.com/ dealer-tech_resources/power_calculator.asp) to
help calculate how much power is needed for the system.
NOTE: When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate to your specific system configuration, available from the
Downloads | Product Manuals | Wiring Diagrams section of the Crestron website
(www.crestron.com).
When calculating the wire gauge for a particular Cresnet run, the length of the run
and the power factor of each Cresnet unit to be connected must be taken into
consideration. If Cresnet units are to be daisy-chained on the run, the power factor of
each network unit to be daisy-chained must be added together to determine the
14 • QuickMedia™ Matrix Switcher/Mixer: QM-MD7x2
Operations Guide - DOC. 6273
Crestron QM-MD7x2

power factor of the entire chain. The length of the run in feet and the power factor of
the run should be used in the following resistance equation to calculate the value on
the right side of the equation.
Resistance Equation
R < 40,000
L x PF
Where: R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).

NOTE: All network wiring must consist of two twisted pairs. One twisted pair is
the +24V conductor and the GND conductor. The other twisted pair is the Y and Z
conductors.
NOTE: When daisy-chaining Cresnet units, strip the ends of the wires carefully to
avoid nicking the conductors. Twist together the ends of the wires that share a pin on
the network connector, and tin the twisted connection. Apply solder only to the ends
of the twisted wires. Avoid tinning too far up the wires or the end becomes brittle.
Insert the tinned connection into the Cresnet connector and tighten the retaining
screw. Repeat the procedure for the other three conductors.
NOTE: For larger networks (i.e., greater than 28 network devices), it may become
necessary to add a Cresnet Hub/Repeater (CNXHUB) or Cresnet Network Poll
Accelerator (C2N-NPA8) to maintain signal quality throughout the network. Also,
for networks with lengthy cable runs, it may be necessary to add a Hub/Repeater
after only 20 devices.
QuickMedia Wiring
The Crestron QuickMedia cable (sold under the name “Crescat-QM”) contains one
CAT5E cable and one Cresnet cable in siamese jackets. Installation of any QM
device is as simple as installing one set of QM wires from the output of one device to
the input of another. Installations are flexible, affordable, and fast.
Operations Guide - DOC. 6273

Crestron QM-MD7x2
CRESCAT-QM Cable
NOTE: Do not untwist the two wires in a single pair for more than 1/3-1/2” (0.84 1.27 cm) when making a connection. The twists are critical to canceling out
interference between the wires.
The QM transport mechanism (receiver) uses frequency compensation on each
twisted pair video input to maintain high resolutions (1600 x 1200) with CRESCATQM cable (which contains both Cresnet and CAT5E wiring) and most good quality
CAT5E and CAT6 cables (where skew rating is ≤ 15 ns / 100 meters). The total
accumulated length of the cable determines the actual skew. For example, when
connecting the QM-WMC to a QM-MD7x2 and then to the QM-RMCRX, the total
accumulated skew must not exceed 15 ns and the total cable length cannot exceed
300 feet.
NOTE: The length of CAT5/5E/6 cable that can be used can vary. However, the
total skew must be ≤ 15 ns.
NOTE: Longer lengths of cable may experience eventual loss of bandwidth when
viewing higher resolution sources.
The following diagram illustrates how composite, S-video, and RGB video signals
are transmitted over the CAT5E wire.
Quick Media Video Signals on CAT5E
NOTE: When transmitting S-video or composite video, luminance uses the green
video pathway, chrominance uses the red video pathway, and composite uses the
blue video pathway.

Identity Code
All equipment and user interfaces within the network require a unique identity code
(Net ID). These codes are two-digit hexadecimal numbers from 03 to FE. The Net ID
of each unit must match an ID code specified in the SIMPL Windows program.
Refer to “Setting the Net ID in Device Settings” on page 25 for details of the SIMPL
Windows procedure.
Refer to the note on page 68 for a
definition of Viewport.
The Net ID of the MD7x2 has been factory set to 08. The Net IDs of multiple
MD7x2s in the same system must be unique. Net IDs are changed from a personal
computer (PC) via the Crestron Viewport.
NOTE: For detailed information on establishing communication between the PC and
control system, refer to “Communication Settings” on page 68. If communication
cannot be established, refer to the “Troubleshooting Communications” section in the
respective Operations Guide for the control system.
There are two different methods—Method A or Method B—for setting the Net ID:
Method A (Cresnet address-settable ID), described on the following page, applies to
devices in a Cresnet system with a 2-Series control system that require a single unit
be the only network device connected to the control system.
Method B (Touch Settable ID or TSID), which begins on page 18, applies to all
TSID-ready devices in a Cresnet system with 2-Series control system upgrade file
(CUZ) version 3.029 or later. TSID functionality makes it possible for the control

Setup is easy thanks to Crestron’s Windows-based programming software.
Crestron’s SystemBuilder software creates a complete project, with no special
programming required. SystemBuilder completes all necessary programming for a
base system including all touchpanel screens and the control system program. The
program output of SystemBuilder is a SIMPL Windows program with much of the
functionality encapsulated in macros and templates. Once SystemBuilder creates the
project, the system interfaces and program logic can be customized in SystemBuilder
or can be easily modified with Crestron development tools (i.e., SIMPL Windows
and Crestron VisionTools® Pro-e (VT Pro-e) software packages).
SystemBuilder comes with templates for all supported interfaces. If a user wishes to
create a touchpanel project using templates with a different look-and-feel, this can be
accomplished by making a custom template. This custom template can then be used
by SystemBuilder to create the final project files to be loaded into the panels.
Alternatively, VT Pro-e can be used to tweak projects created with the
SystemBuilder or develop original touchpanel screen designs.
Once the program created by SystemBuilder is loaded into the control system,
Digital Media Tools (DMT) Software can be used to tune the system for optimal
performance. DMT software can be used to test the quality of audio and video
signals as well as fine-tune audio and video settings.
NOTE: Crestron recommends the use of SystemBuilder and Digital Media Tools
software for creating and fine-tuning a QuickMedia system.
NOTE: Crestron recommends that you use the latest software to take advantage of
the most recently released features. The latest software is available from the
Downloads | Software Updates section of the Crestron website (www.crestron.com).

Programming with SIMPL Windows
NOTE: While SIMPL Windows can be used to program the MD7x2, it is
recommended to use SystemBuilder and Digital Media Tools software for
configuring and tuning a QuickMedia system.
NOTE: The following are acceptable file extensions for programs that include a
MD7x2, developed for specific control system types:
.smw: projectname.smw (SIMPL Windows source file)
.spz: projectname.spz (compiled file for 2-series)
.usp: projectname.usp (source code module for SIMPL+)
.umc: projectname.umc (user macro for SIMPL)
SIMPL Windows is Crestron's software for programming Crestron control systems.
It provides a well-designed graphical environment with a number of workspaces
(i.e., windows) in which a programmer can select, configure, program, test, and
monitor a Crestron control system. SIMPL Windows offers drag and drop
functionality in a familiar Windows environment.
NOTE: The following assumes that the reader has knowledge of SIMPL Windows.
If not, refer to the extensive help information provided with the software.
NOTE: In the following description, the QM-RMCRX control system is used.
This section explains how to create a SIMPL Windows program that includes an
MD7x2.
Configuration Manager is where programmers “build” a Crestron control system by
selecting hardware from the Device Library. In Configuration Manager, drag the
QM-RMCRX from the Control Systems folder of the Device Library and drop it in
the upper pane of the System Views. The QM-RMCRX with its associated
communication ports is displayed in the System Views upper pane.

NOTE: This procedure sets the Net ID for the MD7x2 in the program only. It does
not automatically set the Net ID for the MD7x2 itself. SIMPL Windows
automatically changes Net ID values of a device added to a program if a duplicate
device or a device with the same Net ID already exists in the program. Always
ensure that the hardware and software settings of the Net ID match. For Net ID
hardware setting details, refer to “Identity Code” on page 17.
QM-MD7x2 Symbols in Programming Manager
Programming Manager is where programmers “program” a Crestron control system
by assigning signals to symbols. The MD7x2 is broken down into eight slots. Each
slot contains a programming symbol for specific functions of the MD7x2.
The programming symbol in slot (Slot 1) is for programming the switching functions
of the MD7x2. The second slot (Slot 2) is for programming the MD7x2’s local
microphone controls. Slot 3 is for programming the equalizer (EQ) settings for the
microphone signals that are received on the two QM inputs. Slot 4 contains the
programming symbol for the QM1/Audio Output 1 mixer controls while Slot 5
contains the programming symbol for the QM2/Audio Output 2 mixer controls. Slots
6 and 7 contain the programming symbols for the respective Audio output’s graphic
EQ controls. Slot 8 is for programming the MD7x2’s general audio controls.
The following describes each of the symbols contained in the MD7x2 object in the
SIMPL Windows Programming Manager.
Slot 1: Input Switching
The Input Switching module is built into Slot 1 of the MD7x2. It provides a 7-input,
2-output audio/video crosspoint.
The MD7x2 provides the following local video inputs:
•
Three sets of (three) BNC inputs labeled 1, 2 and 3, which accept up to
three composite, S-Video or component video sources.
•
Two RGB video inputs labeled RGB 4 and RGB 5, for computer sources.
The MD7x2 provides the following local audio inputs:
•
Five stereo line-level unbalanced audio inputs labeled AUD 1 through AUD
5.
•
Two dual-purpose microphone/line-level inputs labeled MIC 1 and MIC 2.
26 • QuickMedia™ Matrix Switcher/Mixer: QM-MD7x2
Operations Guide - DOC. 6273
Crestron QM-MD7x2
QuickMedia™ Matrix Switcher/Mixer
In addition to the local AV inputs, the unit provides two QM inputs labeled IN 6 and
IN 7 that each receive video, stereo program audio and two channels of microphone
audio (MIC 1 and MIC 2) from QM transmitters via CAT5.
At each QM input is a QM audio receiver circuit that supports up to 100 "QM Link"
presets for peaking and boost. The peaking and boost settings improve the
transmission of the encoded audio signal over long cable lengths.
The two QM outputs are labeled OUT 1 and OUT 2. The unit also provides two linelevel audio outputs labeled AUDIO OUT 1 and AUDIO OUT 2. Each line-level
output consists of three channels labeled PRG L, PRG R and SP.
•
Any of the seven video sources can be switched into either QM output.
•
Any of the seven program audio sources can be switched into the stereo
program channel of QM OUT 1 or 2. The audio source that is switched to
QM OUT 1 will also be routed to the mixing section of AUDIO OUT 1.
The audio source that is switched to QM OUT 2 will also be routed to the
mixing section of AUDIO OUT 2.
•
Either of the two remote microphone pairs from QM IN 6 and QM IN 7 can
be mixed with the two local microphones and routed to the MIC 1 channel
of QM OUT 1 or 2. There are no microphone signals on the MIC 2 channels
of the QM outputs. The mic mix that is routed to QM OUT 1 will also be
routed to the mixing section of AUDIO OUT 1. The mic mix that is routed
to QM OUT 2 will also be routed to the mixing section of AUDIO OUT 2.
The Input Switching symbol provides two methods for sending switching commands
to the MD7x2:
1.
By programming the digital and analog signals, or
2.
By programming serial strings.
The two methods should not be used simultaneously.
While using the SIMPL Windows programming manager, double-click on Slot 1 of
the QM-MD7x2 to view the details of the Input Switching symbol as shown in the
following diagram.

Gating eliminates unwanted background noise that
could prove distracting when amplified. The noise
gate will not pass an audio signal unless it is
above the threshold, set by the GatingLevel input.
Enables the 48V phantom power supply for MIC 1
or MIC 2, for as long as the input remains high.
Phantom power is required by condenser
microphones, but should be disengaged for

DESCRIPTION
Sets the threshold for gating.
The noise gate is enabled for as long as the
GatingEnable input is high.
Valid gating values range from 0% to 100%.
Once the microphone audio rises above
GatingLevel the gate opens, allowing the signal to
pass through. If the MicNominal feedback pulses
while the MicGate feedback remains low, this
indicates a threshold that is set too high.
Adjusts the gain of the MIC 1 or MIC 2 input.
Valid values range from 0% to 100%. This maps
into the following ranges:
Mic-level input: -60 dBV to -20 dBV
(-58 dBU to -18 dBU)
Line-level input: -28 dBV to +12 dBV
(-26 dBu to +14 dBu)
Sets the time, in milliseconds, that it takes for the
noise gate to fully open after the signal exceeds
the GatingLevel. This prevents short spikes in the
input signal level, such as coughing, from opening
the gate.
The attack time applies to both microphones.
Valid analog values range from 0d (0ms) to 100d
(100ms), with 10d to 40d being the most usable
range.
Sets the time, in milliseconds, over which the
noise gate will close. This prevents the sound from
stopping too abruptly—for example, during brief
pauses in speech.
The decay time applies to both microphones.
Valid analog values range from 0d (0ms) to 5000d
(5000ms, or 5s), with 1000d to 3000d (1s to 3s)
being the most usable range.

two line-level audio outputs, labeled AUDIO OUT 1 and AUDIO OUT 2.
•
The mic mix that will be routed to QM OUT 1 and AUDIO OUT 1 is
called Mic Mix 1.
•
The mic mix that will be routed to QM OUT 2 and AUDIO OUT 2 is
called Mic Mix 2 (see the Mixer 2 module on slot 05).
•
The two remote microphone channels in Mic Mix 1 are called MIC A-1 and
MIC A-2.
•
The two remote microphone channels in Mic Mix 2 are called MIC B-1 and
MIC B-2 (refer to the Mixer 2 module on slot 05).
The line-level output labeled AUDIO OUT 1 provides a mixing section. The
selected program audio from one of the stereo program sources and the “Mic Mix 1”
mix described previously are input to this mixer. The mixer mixes the program and
the microphone into the three AUDIO OUT 1 channels: PRG L, PRG R, and SP.
The microphone mix can be mixed into the stereo program and the stereo program
can be mixed into the speech.
While using the SIMPL Windows programming manager, double-click on Slot 4 of

stereo program audio and two remote microphone channels (MIC 1 and MIC 2). The
MD7x2 also has two local microphone inputs and five line-level stereo audio inputs
labeled AUD IN 1 through AUD IN 5.
The MD7x2 can mix either of the two remote microphone pairs with the two local
microphones. The same mic mix can be routed to the mixer section of either of the
two line-level audio outputs, labeled AUDIO OUT 1 and AUDIO OUT 2.
•
The mic mix that will be routed to QM OUT 1 and AUDIO OUT 1 is
called Mic Mix 1.
•
The mic mix that will be routed to QM OUT 2 and AUDIO OUT 2 is
called Mic Mix 2 (see the Mixer 2 module on slot 05).

Slot 6: Graphic EQ 1
The MD7x2 provides two line-level audio outputs labeled AUDIO OUT 1 and
AUDIO OUT 2. Each output has three channels labeled PRG L, PRG R and SP.
The MD7x2 provides graphic and parametric EQ for each of the three AUDIO OUT
1 channels. The graphic EQ portion can be programmed using either SIMPL
Windows or Crestron Digital Media Tools (DMT) software. The parametric
equalizer and fixed frequencies of the graphic equalizer can only be programmed
using DMT Software.
The MD7x2 provides 12 filters for each output channel, with a maximum of 10
filters available for graphic EQ. The unit supports five modes of audio equalization
(settable using DMT Software):
•
10 bands graphic EQ + 2 band parametric EQ. In this mode, the first 10
filters of the three channels are used to set up the fixed frequencies for
graphic equalization, leaving filters #11 and #12 available for parametric
EQ. This is the default mode for the graphic EQ.
•
3 bands graphic + 9 bands parametric. In this mode, the first three filters of
the three channels are used to set up the fixed frequencies for graphic
equalization, leaving filters 4 through 12 available for parametric EQ.
•
5 bands graphic + 7 bands parametric. In this mode, the first five filters of
the three channels are used to set up the fixed frequencies for graphic
equalization, leaving filters 6 through 12 available for parametric EQ.
•
5 bands graphic + 7 bands parametric, with speech optimization. In this
mode, the first five filters of the three channels are used to set up the
graphic equalizer within the frequency ranges of the human voice, leaving
filters 6 through 12 available for parametric EQ.
•
12 bands parametric (0 bands graphic). In this mode, all of the filters are
used for parametric equalization.
Programming the graphic equalizer through SIMPL Windows may override the
DMT Software settings. For example, if the 12-band parametric equalizer mode is
selected in DMT and the SIMPL Windows program changes filter #2, the system
will allow the change.

Example Program
An example program for the MD7x2 is available from the Crestron FTP site
(ftp://ftp.crestron.com/Examples/). Search for the file named QM_7x2_DEMO.ZIP
that contains the example program, associated files and a README.TXT file that
describes the program.
Programming with VisionTools™ Pro-e
Touchpanel screens should be created in VT Pro-e to allow switching of source
signals to desired outputs, control audio functions, and recall and/or store preset
settings. There are no special programming requirements to use the functions of the
MD7x2 in a room-control system.

Creating Labels with Crestron Engraver
Use Crestron Engraver software to print custom labels for each input and output
button. Using the templates in Engraver, print labels on 100-pound paper. Paper
weighing less than 100 pounds will be harder to slide in, while paper weighing more
than 100 pounds will not fit.
Uploading and Upgrading
Assuming a PC is properly connected to the entire system, Crestron programming
software allows the programmer to upload programs and projects after their
development to the system and network devices. However, there are times when the
files for the program and projects are compiled and not uploaded. Instead, compiled
files may be distributed from programmers to installers, from Crestron to dealers,
etc. Even firmware upgrades are available from the Crestron website as new features
are developed after product releases. In those instances, one has the option to upload
via the programming software or to upload and upgrade via the Crestron Viewport.
NOTE: The Crestron Viewport is available as a pull-down command from SIMPL
Windows and VT Pro-e (Tools | Viewport) or as a standalone utility. The Viewport
utility accomplishes multiple system tasks, primarily via an RS-232 or TCP/IP
connection between the control system and a PC. It is used to observe system
processes, upload new operating systems and firmware, change system and network
parameters, and communicate with network device consoles and touchpanels, among
many other tasks. Viewport can also function as a terminal emulator for generic file
transfer. All of these functions are accessed through the commands and options in
the Viewport menus. Therefore, for its effectiveness as a support and diagnostic tool,
the Crestron Viewport may be preferred over development tools when uploading
programs and projects.
The following sections define how one would upload a SIMPL Windows program or
upgrade the firmware of the MD7x2. However, before attempting to upload or
upgrade, it is necessary to establish communications.
Communication Settings
NOTE: For laptops and other PCs without a built-in RS-232 port, Crestron
recommends the use of PCMCIA cards, rather than USB-to-serial adapters. If a
USB-to-serial adapter must be used, Crestron has tested the following devices with
good results:
Belkin (large model) F5U103
I/O Gear GUC232A
Keyspan USA-19QW (Discontinued)
Results may vary depending on the computer being used. Other models, even from
the same manufacturer, may not yield the same results.
The procedure in this section provides details for RS-232 communication between
the PC and the control system. If TCP/IP communication is preferred, consult the
latest version of the Crestron e-Control Reference Guide (Doc. 6052) or the
respective Operations Guide for the control system. These documents are available
from the Downloads | Product Manuals section of the Crestron website

Adjusting the Local Microphone Inputs
Once an MD7x2 is installed and configured, settings for gain, gating level, attack
time, and decay time must be set using the Realtime Mode in Digital Media Tools
(version 3.00.00 or later). Digital Media Tools software can be started from the
SystemBuilder application.
NOTE: Crestron recommends that you use the latest software to take advantage of
the most recently released features. The latest software is available from the
Downloads | Software Updates section of the Crestron website (www.crestron.com).
Definitions
The MD7x2 allows adjustments to be made to microphone input signals. Following
are definitions of terms that are commonly used when making adjustments to the
MD7x2.
Attack Time
The time it takes (in milliseconds) from when an input signal rises above the gating
level until the microphone output signal is enabled.
Clipping
A condition in which a signal level exceeds the maximum level (the clipping level) a
circuit can handle. This is usually caused by improper gain settings.
Decay Time
The time (in milliseconds) from when an input signal falls below the gating level
until the microphone output signal is muted.
Gain
An adjustable amplification to accommodate varying input signal levels.
Gating
A function that mutes a microphone signal when the input sound level is below a
user-set threshold (Gating Level).
The following diagram demonstrates Clipping, Attack Time, Decay Time, and
Gating level.

Setting Microphone Gain
The MD7x2 provides variable gain on the local microphone inputs. The gain setting
for each local microphone input can be adjusted. Gain settings for the remote
microphone inputs are performed at the source device (e.g. QM-WMIC). The
following procedure is used to set the optimal gain for a microphone input.
Use the Realtime Mode in Digital Media Tools to control phantom power, gain and
gate settings, and to monitor the gate, normal, and clip level indicators. For
Operations Guide - DOC. 6273
QuickMedia™ Matrix Switcher/Mixer: QM-MD7x2 • 75
QuickMedia™ Matrix Switcher/Mixer
Crestron QM-MD7x2
information on using Digital Media Tools software, refer to the extensive help
information provided with the software.
NOTE: The input gain is independent of the system’s output volume level.
1.
To adjust the input gain, set the gain and noise gate for microphone 1 to
their lowest settings. Disable the “Mute” function by removing the
check from the Mute checkbox.
2.
Connect a microphone and enable phantom power if required.
3.
Increase the gain for microphone 1 while providing a “normal” sound
level input to the microphone. When the “Norm” indicator shows fairly
consistent activity, you’ve reached a good signal level for the local
microphone input.
NOTE: The "clip" indicator shows that the signal is clipping. Let your ears be the
judge, but when the clip indicator is active, you are approaching or have reached
distortion in local microphone signal. Occasional clip indications on loud input are
expected, but constant clip indicator activity is a sign that the gain may be set too
high.
4.
Set the system output volume to a desirable listening level and verify
the gain settings by listening to the system output. Some minor gain
adjustment may be required for the “best sound” in any specific
configuration.
5.
Repeat for the second microphone input.
Setting the Gating Level
The MD7x2 provides an input level gating function that will mute the local
microphone signal when the input sound level is below a user-set threshold. This
function can be enabled or disabled via software commands.
Use the Realtime Mode in Digital Media Tools to control phantom power, gain and
gate settings, and to monitor the gate, normal, and clip level indicators. For
information on using Digital Media Tools software, refer to the extensive help
information provided with the software.
The following procedure sets the optimal “gate level” for the microphone inputs:
1.
Follow the “Setting Microphone Gain” procedure on page 75 to set the
gain for each microphone input.
2.
Set the noise gate level, attack and decay times to minimum. Disable
the “Mute” function by removing the check from the Mute checkbox.
3.
While providing a level to the microphone that is equivalent to the
background noise that should be gated out, increase the noise gate level
for microphone 1 until the Gated indicator turns off. When the input
sound levels are at or below the established noise gate level, the
microphone output signal will be gated off. Repeat for the second
microphone input.
4.
Set the “attack time” to the minimum level and the “decay time” to the
maximum level. These settings provide the shortest time to enable the
microphone output when an input is above the gating level, and the
longest time before disabling the microphone after such an input.
76 • QuickMedia™ Matrix Switcher/Mixer: QM-MD7x2
Operations Guide - DOC. 6273
Crestron QM-MD7x2
QuickMedia™ Matrix Switcher/Mixer
NOTE: The “attack” and “decay times” are applied to both local microphone
inputs.
5.
Set the system output volume to a desirable listening level. While
providing realistic voice input and background noise levels, adjust the
gating level and attack/decay times to eliminate undesired input while
providing the best content quality.
NOTE: Settings for gain, gating levels, attack time, and decay time will be
maintained in the event of power failure.
Operation
Operating Modes
The MD7x2 operates in either the system mode or the local mode. When operating in

All commands and responses are printable ASCII and are terminated with a <CR>
(\x0D).
The serial commands listed here are grouped into front panel functions, verbose
mode functions, and switching/routing functions.
Multiple serial commands cannot be strung together.
NOTE: When programming the MD7x2 using serial commands, digital and analog
switching commands should not be used. However, digital and analog mixing
commands can still be used. Similarly, if the MD7x2 is to be programmed with
digital and analog switching commands, serial commands should not be used.

FUNCTION
Unlock front panel
Lock front panel
Get lock status
If the MD7x2 is in the local mode and the “Lock front panel” is sent, the MD7x2
will switch to the system mode and use the switching schema specified by the
control system. If the MD7x2 is already in the system mode, the operating mode will
not change.
When set via serial command, the front panel lock setting is not retained when power
to the MD7x2 is recycled. To retain the panel lock setting, a digital signal must be
used.
When the verbose mode is on and the lock state changes, or if the MD7x2 is polled
for the status of the front panel lock, the MD7x2 replies with one of the responses
listed in the following table.

DEFINITION
Front panel is locked

Verbose Mode Functions
The MD7x2 has a verbose mode, which can be turned on or off via serial commands
only. The verbose mode is used to automatically report any changes made to the
switching schema. The default setting for the verbose mode is off. If the verbose
mode is on, whenever a parameter of the switch changes, a message is sent from the
MD7x2 that indicates the new state of the parameter. If verbose mode is off, the
MD7x2 will only send messages when queried.
The setting for the verbose mode is retained even after power to the MD7x2 is
cycled.
Commands can be sent to the MD7x2 regardless of the status of the verbose mode.

Switching/Routing Functions
Switching/Routing Commands
COMMAND*
FUNCTION*
IxOyA\r
IxOyV\r
IxOyM\r
Switch input x to output y audio only*
Switch input x to output y video only*
Switches the remote microphone inputs to
outputs 1 or 2. Where “x” can be equal to 0
(off), 1 (QM6 microphones), or 2 (QM7
microphones). “y” can be equal to 1 or 2.
Switch input x to output y audio and video*
Switches all outputs. Where A1 is the audio
input routed to QM OUT 1, V1 is the video
input routed to QM OUT 1, M1 is the remote
microphone input (QM6 or QM7) routed to
QM1, A2 is the audio input routed to QM OUT
2, V2 is the video input routed to QM OUT 2,
and M2 is the remote microphone input (QM6
or QM7) routed to QM2. Each audio and video
input value is 2 digits, and thus can range from
00 (for no source) to 07, corresponding to
inputs 1 through 7. Acceptable microphone
switching values are 00 (for no microphone),
01 (for QM6 microphone), or 02 (for QM7
microphone). The "XX" (or "xx") specifier
should be used to denote a "don't care"
condition, in which case the respective output
should retain its state.

Where “x” should equal 0 (for no source) through 7, corresponding to inputs 1
through 7; and “y” should equal 1 through 2, corresponding to outputs 1
through 2. Thus to route a digital audio source from IN 4 (RGB) to QM OUT 2,
set the Control$ input to “I4O2A\r”. Alternatively, the command string can
consist of 2-digit values, e.g.,“I04O02A\r”.
Any switches made to the microphone or audio inputs will use the current mixer
settings.

NOTE: If an input greater than “7” or “07” is sent, the command is ignored. If an
output destination less than “1” / “01”, or greater than “2” / “02”is sent to the
MD7x2, the command is ignored.
When the verbose mode is on and the routing status changes while the MD7x2 is in
the system mode, or if the MD7x2 is polled for the status of an output, the MD7x2
replies with one of the responses listed in the following table.

DEFINITION
New audio route if audio route has changed
where x will be a two-digit number from 00 to
07 and y will be a two-digit number from 01 to
02.
New video route if video route has changed
where x will be a two-digit number from 00 to
07 and y will be a two-digit number from 01 to
02.
Current switching schema of all of the outputs
where a1 is the input routed to output 1 audio,
v1 is the input routed to output 1 video, m1 is
the microphone input routed to output 1
microphone, a2 is the input routed to output 2
audio, v2 is the input routed to output 2 video,
and m2 is the microphone input routed to
output 2 microphone. Each number will be two
digits.
If a switch command is sent and an output is already at the new setting, serial
feedback will not be provided for that output.
NOTE: There is no serial feedback for any switches made while the MD7x2 is in
the local mode, even if the verbose mode is on. Use the LocalMode-FB digital
signal to signal when the device leaves local mode in order to trigger the “S?\r”
command to query the MD7x2 for the current status of all outputs.
“Switch All” Example
The string “C020400050102\r” sends the following command:
•
Switch Audio Input 2, Video Input 4 and no microphone signal to QM Out
1.
•
Switch Audio Input 5, Video Input 1, and the microphone signals from
QM7 to QM Out 2.
If polled for the status of all outputs (S?\r), the device response on Control-FB$ will
be: “S020400050102\r”.
