Shure has announced a handsfree mode for its Microflex Complete Wireless Conference System (MXCW) is available now with firmware version 7.0 or later.
The new mode automatically activates microphones when it detects voice. When the participant stops talking, their mic shuts off. Users can toggle between handsfree, manual, or remote microphone activation.
In handsfree mode, each conference unit evaluates the level, spectral content, and signal-to-noise ratio of the audio at its microphone to determine when speech is present. The conference unit sends a “request to speak” signal to the MXCW’s Access Point Transceiver (MXCWAPT). Next, the MXCWAPT assigns it a transmission channel and adds its audio to the floor mix.
