What a great idea. The Optogate sits on between the XLR lead and the microphone, is powered by phantom power (which it can pass on to the mic if needed), and waits until it senses that someone, or something is in front of the mic before it opens up the signal. Step away and it closes.
If youâ€™ve ever had to do live sound with a particularly loud on-stage sound and lots of vocal mics, youâ€™ll see where this is going to fit right in.
Using optical sensing to see if thereâ€™s anything close to the mic, it means that all unused mic sources â€“ BVâ€™s singing drummers, etc etc stay muted â€“ simple.
Believe me, the overworked sound engineer will be much happier sipping his pint than second guessing the intentions of a random singer to mute and unmute the signal on the board.
Nice work. Should be somewhere around 130 Euros.
