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
