Crestron QM-WMC/WMC-VCC/WCC-2 Media & Computer Centers
Wall Mount Multimedia Interface
(QM-WMC & QM-WMC-VCC only)
The QM-WMC and QM-WMC-VCC install cleanly in a standard two-
gang electrical box using a decorator style faceplate (not supplied).
Individual video inputs are provided for composite, S-video*and
RGB/component signals, each with corresponding stereo audio, to accept
connections from portable AV devices and computers. A buffered
monitor pass-through connector is also provided to feed the RGB input
signal to a local monitor.
Connectivity for LAN and other signals can easily be added by ganging
the QM-WMC or QM-WMC-VCC together with other third-party wall
plate devices. A Crestron C2N-DB series Decorator Keypad may also be
installed for a truly complete multimedia interface and control solution.
Wiring for the QM-WMC and QM-WMC-VCC is extremely simple
requiring just a single CresCAT™QM cable (sold separately).
* S-video (Y/C) on QM-WMC-VCC may require an appropriate adapter or
breakout cable (not included) to connect to the COMPONENT input.
Wall Mount Computer Interface (QM-WCC-2 only)
The QM-WCC-2 installs cleanly in a standard two-gang electrical box
using a decorator style faceplate (not supplied). Dual RGB and stereo
audio inputs are provided to accept connections from two separate
computers or other RGB sources. Buffered monitor pass-through
connectors are also provided, allowing RGB input signals to be fed to
local monitors.
Connectivity for LAN and other signals can easily be added by ganging
the QM-WCC-2 together with other third-party wall plate devices. A
Crestron C2N-DB series Decorator Keypad may also be installed for a
truly complete multimedia interface and control solution. Wiring for the
QM-WCC-2 is extremely simple requiring just a single CresCAT-QM
cable (sold separately).
AV Switcher
The built-in 3x1 switcher in the QM-WMC and QM-WMC-VCC
includes audio breakaway to allow the three program audio inputs to be
switched independent of the video and RGB inputs or linked with them.
Built-in video sensing on every video/RGB input can be utilized to
trigger automatic input selection and power control.
Operations & Installation Guide – DOC. 6237C Wall Plate Media & Computer Centers •3

Media & Computer Centers Crestron QM-WMC/WMC-VCC/WCC-2
The built-in 2x1 switcher in the QM-WCC-2 includes audio breakaway
to allow two PC audio inputs to be switched independent of their
corresponding RGB inputs or linked with them. Built-in video sensing on
each RGB input can be utilized to trigger automatic input selection and
power control.
Gated Mic Preamp (Optional)
Two gated microphone inputs may be added using the QM-WMIC
Microphone Input Module (sold separately). Via two Neutrik®Combo
connectors, the QM-WMIC supports both dynamic and condenser type
microphones with software switchable 48V phantom power available at
both XLR inputs. Balanced or unbalanced line level sources can also be
accommodated using 1/4” TRS connections. 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-WMC/WMC-VCC/WCC-2 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 with a delay skew of ≤15 ns per 100 meters;
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 details.
MediaManager System Integration
Whether using just one Wall Plate Media or Computer Center 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. Complete MediaManager systems are

easy to design, program and adjust from start to finish using Crestron
SystemBuilder software.
EDID Format Management (QM-WMC-VCC and QM-WCC-2
only)
The QM-WMC-VCC and the QM-WCC-2 allow for management of the
EDID (Extended Display Identification Data) information sent to the
connected source. Using Crestron Toolbox™software, the format and
resolution capabilities of each device can be assessed and managed through
the QM-WMC-VCC and the QM-WCC-2, ensuring reliable operation by
instructing sources to output only the resolutions and formats that can be
handled by the displays and system wiring.
Applications
The following diagram shows a QM-WMC-VCC and QM-WCC-2 in a
lecture hall application.
