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.
