Crestron QM-WMIC Wall Plate Media Center Microphone Input
Wall Plate Media Center
Microphone Input: QM-WMIC
Introduction
Features and Functions
The Wall Plate Media Center Microphone Input (QM-WMIC) is an
optional part of the Crestron MediaManager™ line of network devices,
room control systems, and signal routing solutions.
The QM-WMIC is a complementary accessory that can only be used
when installed with a Crestron®QM-WMC Wall Plate Media Center.
The QM-WMIC adds two Neutrik®Combo microphone connectors with
software enabled phantom power to the A/V connections that are present
on the QM-WMC. The microphone inputs feature adjustable gain and an
integrated noise gate with adjustments for gating level, attack time, and
decay time. The microphone signals are transmitted with the program
audio over the Crestron QuickMedia transport.
A QM-WMIC requires a QM-WMC, the far-right space in a 2½” deep,
triple-gang electrical box and a Decora®style faceplate (sold by other)
for installation.
Functional Summary
• 3-gang Decora style (requires installation with QM-WMC)
• Two Neutrik Combo microphone connectors with muting and
software switchable phantom power (48V @ 10mA) for
condenser microphones
• Adjustable gain, noise gate levels, attack time, and decay time

Physical Description
The QM-WMIC features two Neutrik Combo XLR/¼” ports that allow
for connection of up to two microphones. The XLR microphone
connectors feature software switchable phantom power for use with
condenser microphones. Microphone signals are transmitted along with
the program audio and can be manipulated at the receiver.
NOTE: Phantom power is applied to the XLR connectors of both
microphone inputs. It cannot be switched on an individual microphone
input.
An LED on the front of the QM-WMIC indicates whether phantom
power is enabled. The following illustration shows the QM-WMIC
properly installed with a QM-WMC.
NOTE: Decorative faceplates, as shown in the following illustrations,
are not supplied.
