QuickMedia™ FlipTop Computer Center Crestron QM-FTCC
FlipTop Housing
Handsomely finished in either black anodized or brushed aluminum, the QM-FTCC
mounts flush in any tabletop surface for a clean, professional appearance. The sleek
design of the “FlipTop” lid features an integrated keypad (keypad models only) to
provide programmable pushbutton control at every interface location. Wiring for the
QM-FTCC is extremely simple requiring just a single CresCAT™-QM cable (sold
separately).
Computer Interface
Inputs are provided for one RGB/component signal with corresponding stereo audio
to accept a connection from a computer or other high-resolution source. For
complete connectivity, the QM-FTCC also includes an RJ-45 LAN pass through
connector and AC power receptacle.
Integrated Keypad (optional)
The QM-FTCC can be ordered with or without a keypad. This customizable keypad
provides 10 to 20 programmable pushbuttons for control of AV, lighting and other
functions. All button caps are engravable and include LED feedback indicators. Two
LED bar graphs are also provided to display level settings and other parameters. To
prevent accidental button presses, the keypad is automatically disabled whenever the
lid is not fully opened.
Gated Mic Preamp
Two gated microphone inputs are included via terminal block connectors located
below the table surface. Both dynamic and condenser type microphones are
supported with software switchable 48V phantom power available at both
microphone inputs. Balanced or unbalanced line level sources such as wireless
microphones can also be accommodated. Input gain and gating controls for each
microphone/line input are fully adjustable at setup and can also be controlled in real
time from a keypad or touchpanel.
QuickMedia™ Transport
Using Crestron’s revolutionary QuickMedia (QM) transport, all input signals are
transmitted from the QM-FTCC to any QuickMedia Receiver or Distribution Center
over a single inexpensive CAT5e type cable. Computer resolutions up to 1920 x
1200 pixels at 60 Hz are supported over cable runs up to 450 feet (137 meters).
Audio signals are transmitted digitally with high performance 24-bit resolution.
QuickMedia dramatically simplifies system design and installation, affording a
higher level of performance at a lower overall cost.
NOTE: For QuickMedia wiring use CresCAT-QM, CresCAT-IM or quality
Cat5e/CAT6 cable. The maximum aggregate cable length and delay skew between
any QM transmitter (origination point) and QM receiver (endpoint) is 450 feet (137
meters) and 22 ns. A maximum of two QM midpoint devices may be inserted in a
given QM signal path (exceptions apply, refer to each respective product manual for
full details).
MediaManager System Integration
Whether using just one FlipTop box or several, 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 can be
utilized to trigger automatic input selection and power control. Complete

Crestron QM-FTCC QuickMedia™ FlipTop Computer Center
Setup
Network Wiring
When wiring the Cresnet® network, consider the following:
• Use Crestron Certified Wire.
• Use Crestron power supplies for Crestron equipment.
• Provide sufficient power to the system.
CAUTION: Insufficient power can lead to unpredictable results or damage
to the equipment. Please use the Crestron Power Calculator to help calculate
how much power is needed for the system (www.crestron.com/calculators
• For larger networks, use a Cresnet Hub/Repeater (CNXHUB) to maintain
signal quality.
For more details, refer to “Check Network Wiring” which starts on page 34.
).
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 CresCAT-QM wires from the output of one device to
the input of another. Installations are flexible, affordable and fast. For more
information, refer to the latest revision of the Crestron MediaManager Applications
Guide (Doc. 6244), which is available for download from the Crestron website
(www.crestron.com/manuals
CresCAT-QM Cable
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.
Operations & Installation Guide – DOC. 6313B QuickMedia™ FlipTop Computer Center: QM-FTCC • 15
QuickMedia™ FlipTop Computer Center Crestron QM-FTCC
The aggregate cable length of a signal path originating at a QM-FTCC and
terminating at a QM receiver must not exceed 450 feet (137 meters). Video signals
may experience a loss of quality over very long lengths of cable. This phenomenon is
due to the added resistance and capacitance of longer cable lengths and is not
peculiar to either Crestron and/or QuickMedia systems. To ensure sufficient
bandwidth, the maximum aggregate cable length should not exceed 450 feet. The use
of lower-resolution signals may allow increased cable length but must be tested by
the installer with the sources to be used. The QM pin assignment is based on the
EIA/TIA 568B RJ-45 Jack standard.
NOTE: When using CresCAT-QM wiring, four additional wires are included for
making Cresnet connections.
When connecting multiple QM devices, the route between a QM origination point
(transmitter) and a QM endpoint (receiver) cannot have more than two midpoints
(e.g. QM-MD7x2 or other QM switchers). Refer to the following diagram when
configuring a QM network.
NOTE: The aggregate length from transmitter to receiver cannot have a delay skew
of more than 22 ns.
NOTE: When used with a QM-RMCRX, delay skew should not exceed 15 ns.

Identity Code
The Net ID of the QM-FTCC has been factory set to 1A. The Net IDs of multiple
QM-FTCC devices in the same system must be unique. Net IDs are changed from a
personal computer (PC) via Crestron Toolbox™ (refer to “Establishing
Communication” on page 31).
When setting the Net ID, consider the following:
• The Net ID of each unit must match an ID code specified in the SIMPL™
Windows
®
program.
• Each network device must have a unique Net ID.
For more details, refer to the Crestron Toolbox help file.

Earliest Version Software Requirements for the PC
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 Crestron
website.
Crestron has developed an assortment of Windows-based software tools to develop
a Cresnet system. For the minimum recommended software versions, visit the
Version Tracker page of the Crestron website (www.crestron.com/versiontracker
).
Configuration Manager
Configuring with Crestron SystemBuilder
Crestron SystemBuilder is the easiest method of programming but does not offer as
much flexibility as SIMPL Windows. For additional details, download
SystemBuilder from the Crestron website and examine the extensive help file.
Configuring with SIMPL Windows
NOTE: While SIMPL Windows can be used to program the QM-FTCC, it is
recommended to use SystemBuilder for configuring a QuickMedia system.
SIMPL Windows is Crestron’s premier software for programming Crestron control
systems. It is organized into two separate but equally important “Managers”.
Configuration Manager is the view where programmers “build” a Crestron control
system by selecting hardware from the Device Library.
• To incorporate the QM-FTCC into the system, drag the QM-FTCC from the
Cresnet Control Modules | QM Series folder of the Device Library and drop
it in the System Views.

• The ID code specified in the SIMPL Windows program must match the Net
ID of each unit. Refer to “Identity Code” on page 16.
Program Manager
Program Manager is the view where programmers “program” a Crestron control
system by assigning signals to symbols.
The symbol can be viewed by double clicking on the icon or dragging it into Detail
View. Each signal in the symbol is described in the SIMPL Windows help file (F1).
The buttons module is built into slot 03 of the QM-FTCC (refer to “C2Net Device,
Slot 9” on page 26). It consists of a keypad that provides 10 to 20 buttons with LED
indicators, and two bar graphs. The button presses are fixed and map to <press>
outputs on the symbol detail, as follows:
Row 1
Row 2
Row 3

NOTE: Numbers in this illustration are for programming purposes only.
NOTE: Not applicable to NB models.
The buttons on rows 1 and 2 can be combined vertically to form one larger button.
For example, the button caps for buttons #1 and #6 can be replaced with one larger
button cap. Similarly, the vertical pairs on rows 3 and 4 can be combined to form one
larger button. For example, buttons #13 and #18 can be combined. No other
combinations are valid. That is, two buttons cannot be combined horizontally; the
buttons on rows 2 and 3 cannot be combined.

QuickMedia™ FlipTop Computer Center Crestron QM-FTCC
Adjusting the QM-FTCC Microphone Inputs
Once a QM-FTCC is installed and configured, settings for gain, gating level, attack
time and decay time should be set using the SystemBuilder finish tab.
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 Crestron
website.
Definitions
The QM-FTCC allows adjustments of the microphone input signals. The following
are definitions of terms that are commonly used when making adjustments.
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
An overload condition that occurs when signal level exceeds the maximum level a
circuit can process. This is usually caused by excessive 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 amplification adjustment designed to accommodate varying input signal levels.
Gating
Gating is a function that mutes a microphone signal when the input sound level is
below a user-set threshold (gating level).
The following diagram demonstrates attack time, clipping, decay time and gating
level.

The QM-FTCC provides variable gain for the microphone inputs. The following
procedure is used to set the optimal gain for a microphone input.
Use the Realtime Mode in SystemBuilder to control phantom power, gain and gate
settings and to monitor the gate, normal and clip level indicators. For information on
using SystemBuilder software, refer to the extensive help information provided with
the software.
NOTE: The input gain is independent of the system’s output volume level.
Operations & Installation Guide – DOC. 6313B QuickMedia™ FlipTop Computer Center: QM-FTCC • 29
QuickMedia™ FlipTop Computer Center Crestron QM-FTCC
1. To adjust the input gain, set the gain and noise gate 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 while providing a “normal” sound level input to the
microphone. When the “Norm” indicator shows fairly consistent activity,
you have reached a good signal level for the QM-FTCC.
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 your QM-FTCC 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.
Setting the Gating Level
The QM-FTCC provides an input level gating function that will mute a 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 SystemBuilder to control phantom power, gain and gate
settings and to monitor the gate, normal and clip level indicators. For information on
using SystemBuilder 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 (refer to page 29) 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
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.
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.
NOTE: The “attack” and “decay times” are applied to both 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.

Calculate Power
34 • QuickMedia™ FlipTop Computer Center: QM-FTCC Operations & Installation Guide – DOC. 6313B
In order to ensure optimum performance over the full range of your installation
topology, Crestron Certified Wire and only Crestron Certified Wire may be used.
Failure to do so may incur additional charges if support is required to identify
performance deficiencies because of using improper wire.
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to
do so could cause equipment damage or void the Crestron warranty.
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 to help calculate how much power is needed for the system
(http://www.crestron.com/calculators).
When calculating the length of wire for a particular Cresnet run, the wire gauge and
the Cresnet power usage of each network unit to be connected must be taken into
consideration. Use Crestron Certified Wire only. If Cresnet units are to be daisy-
Crestron QM-FTCC QuickMedia™ FlipTop Computer Center
chained on the run, the Cresnet power usage of each network unit to be daisychained must be added together to determine the Cresnet power usage of the entire
chain. If the unit is home-run from a Crestron system power supply network port, the
Cresnet power usage of that unit is the Cresnet power usage of the entire run. The
wire gauge and the Cresnet power usage of the run should be used in the following
equation to calculate the cable length value on the equation’s left side.
Cable Length Equation
Strip and Tin Wire
Add Hubs
L = Length of run (or chain) in feet
R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 MM ))
or 1.6 Ohms (Cresnet HP: 12 AWG (4 MM ))
P = Cresnet power usage of entire run (or chain)
2
2
L <
40,000
Where:
R x P
Make sure the cable length value is less than the value calculated on the right side of
the equation. For example, a Cresnet run using 18 AWG Crestron Certified Wire and
drawing 20 watts should not have a length of run more than 333 feet. If Cresnet HP
is used for the same run, its length could extend to 1250 feet.
NOTE: All Crestron certified Cresnet wiring must consist of two twisted pairs. One
twisted pair is the +24V conductor and the GND conductor and the other twisted
pair is the Y conductor and the Z conductor.
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.
For larger networks (i.e., greater than 28 network devices), it may become necessary
to add a Cresnet Hub/Repeater (CNXHUB) 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.

Appendix B: QuickMedia Installation and Compensation
Installation Notes
You must pass audio through from transmitters to receivers even if you are not using
the audio signal. The information required for auto-compensation is transmitted
along with the audio. In addition, the QM Link signal indicates that the QM cable is
connected and that an audio signal is present on the cable. If a unit does not receive
an audio signal, the QM Link signal will not go high and a valid QM Link
connection cannot be detected (video can still be displayed if auto compensation is
not used).
Certain devices terminate and re-initialize the audio path within the unit however,
they pass the video untouched. This creates different path lengths for the video and
audio. This difference in path length creates different peak and boost levels for audio
and video. When audio-breakaway is implemented, the audio and video paths are
likely to be different.
Compensation
Twisted pair cables experience a loss of bandwidth and signal strength over distance.
When the loss is within certain limits, the reduced signal can be restored through
peak and boost compensation adjustments. The amount of compensation required is
directly dependent on the length of the cable. Therefore, each device in a network
requires a specific amount of compensation.
Manual Compensation
In a manual compensation system, the compensation parameters, along with
microphone equalization settings, are stored in the receiver in a preset file. When the
program switches to a new transmitter, the program recalls the compensation settings
associated with the new transmitter. In large systems containing multiple transmitters
and receivers, these parameters must be stored in multiple locations, creating a
complex arrangement.
Auto Compensation
In a system utilizing auto compensation, the peak and boost values are stored in a
preset file at the receiver. The transmitter stores the input compensation and
microphone EQ settings. When the program switches to a new transmitter, the
transmitter ID, input compensation and microphone EQ settings are sent over the
audio channel of the QM cable to the receiver. The receiver is equipped with a hunt
algorithm to search for the proper peak and boost settings. Once the receiver acquires
a QM Link signal, it can receive the audio signal containing the transmitter ID, input
compensation and microphone EQ settings. After receiving the transmitter ID, the
receiver recalls the peak and boost preset and uses these values to properly adjust the
video signal.
NOTE: If auto compensation is used in your QM system, all QM devices must use
it. If it is not used in your QM system, it must not be used for any of the QM devices.

Auto Compensation with a Self-Peaking Receiver
Crestron's innovative self-peaking audio circuit eliminates the need to peak the audio
signal.
Without self-peaking, the same peak and boost values are applied equally to the
video and audio signals. When these signals travel the same path, this arrangement is
satisfactory. However, when video and audio travel to a receiver from different
paths, cable lengths are unequal. The self-peaking feature eliminates the need to hunt
for peak and boost values by allowing the receiver to read the ID, input
compensation and microphone EQ from the audio channel regardless of the peaking
and boost values applied. Then using the transmitter ID, the receiver recalls the
preset containing the proper peak and boost settings for the video and implements the
correct input compensation and microphone EQ settings.
QM devices that do not have self-peaking include:
• QM-RMCRX
• QM-MD7x2
• QM-MD5x1
• TPMC-15-QM
• TPMC-17-QM
Switchers
The QM-MD7x2 and the QM-MD5x1 terminate and re-initialize the audio path
within the unit, however, they pass the video untouched. This creates different path
lengths for the video and audio. This difference in path length creates different peak
and boost levels for audio and video. In the initial QM receivers the video and audio
circuits, peak/boost have the same settings for the audio and video. The initial QM
receivers cannot accommodate different settings and may experience difficulties
resolving the signals.
The QM-MD8x8 and QM-MD4x2 are simply analog switches. When audiobreakaway is implemented, the audio and video paths are likely to be different. For
receivers without self-peaking audio, a probable conflict exists. For receivers with
self-peaking, auto compensation is still problematic when audio-breakaway is done
since the transmitter ID is that of the audio source and the video source is from a
different device with a different transmitter ID.
The self-peaking audio circuit resolves the problem of unequal cable lengths.
Because no audio setting is required, the video can have an independent peak/boost
as set by the program.
QM-AE Audio Extractor
The QM-AE is an audio-only device. The QM cable loops through the QM-AE from
the input connector to the output connector. The QM-AE taps only the audio signals
of the QM cable. The QM-AE is a self-peaking receiver, so peaking is not required.

Compatibility Charts
Under certain circumstances, the audio and video may be acceptably peaked even
though the audio and video path lengths are different. Because the audio signal is
digital and more forgiving than the video signal, it may be possible to peak the video
and have functioning audio. It is difficult to predict an outcome because it is
dependent on the difference in cable lengths, the video rates and acceptable video
quality.
The following Auto Compensation and Audio Breakaway compatibility charts are
arranged with transmitters listed on the left and receivers listed across the top. The
QM cable exits the transmitter and the QM cable enters the receiver.
NOTE: The cable exiting the QM-AE is a loop-through and is not listed as a
transmitter.
NOTE: QM wall plates and fliptop boxes are not included because the audio and
video cable lengths are always equal.
KEY: = Good operation.
1. = Operation depends on video rates and if the audio and video cable lengths are closely matched.
2. = In these cases, if the audio and video (although from different sources) switch together consistently, the
system will operate normally. If the audio and video switch inconsistently, operation then depends on the
video rates and how closely the audio and video cable lengths match.
* = Device with self-peaking.
