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 MediaManagerTM line of network devices, room control systems, and signal routing solutions. [. . . ] Doubleclick Slot 2 of the QM-WMC symbol to view the details of the QM-WMIC symbol. QM-WMIC Symbol in Programming Manager Programming Manager is where programmers "program" a Crestron control system by assigning signals to symbols. The following describes the QM-WMIC symbol in the SIMPL Windows Programming Manager. NOTE: Many of the signals in the QM-WMIC symbol are used to adjust operating parameters such as gain, gating/gating level, attack time and decay time. For definitions and information on the effects of adjusting these parameters, refer to "Adjusting the QM-WMIC" on page 18. QM-WMIC symbol in SIMPL Windows Programming Manager
The following tables list the symbol's input and output signals, respectively, and their functional descriptions.

Programming with VisionTools Pro-e
Touchpanel screens can be created in VT Pro-e to allow configuration of phantom power, gain levels, gating levels, attack times, and decay times. Digital Media Tools software already has these controls built in. Refer to the section "Adjusting the QM-WMIC" on page 18 for instructions.
Example Program
An example program for the wall plate is available from the Crestron FTP site (ftp://ftp. crestron. com/Examples). Search for the file named QM-WMC_QM-WMIC. ZIP.

Adjusting the QM-WMIC
Once a QM-WMIC is installed and configured, settings for gain, gating level, attack time, and decay time must be set using the Realtime Mode in Digital Media Tools (version 3. 00. 00 or later). Digital Media Tools software can be started from the SystemBuilder application. 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 Downloads | Software Updates section of the Crestron website (www. crestron. com).
