Adds two phantom-powered microphone/line inputs to any 2-gang model QuickMedia Wall Plate Transmitter.

The QM-WMIC is an optional add-on to the QM-WMC, QM-WMC-VCC, and QM-WCC-2 Wall Plate Media Centers, providing two Neutrik® Combo jacks for the connection of microphone sources to the system. Each input accepts balanced microphone level signals via XLR-type connectors, and also accommodates 1/4" phone-type connectors carrying balanced or unbalanced line-level signals (wireless microphone receivers, etc.). Software switchable 48V phantom power is available at both XLR jacks to support either dynamic or condenser microphones.

Input gain and gating controls for each microphone input are fully adjustable at setup, and can also be controlled in real-time from a touchpanel or keypad. As part of a complete MediaManager system, the microphone signals are routed, mixed, and processed separately from the program audio signal providing dedicated EQ, gating, and time delay for optimal intelligibility. At the system output, speech signals may be mixed with the stereo program signal or routed to a dedicated speech output to feed separate loudspeakers.

The QM-WMIC installs alongside a QM wall plate transmitter (sold separately) in a 3-gang electrical box or trim ring. There is no additional wiring required when adding the QM-WMIC.
