FG/BFG Series
The FG Series microphone is the world's smallest electret condenser microphone. Its cylindrical shape and compact size provide for superior fit rates. The FG can also be used in directional applications as a matched omni-directional pair. The BFG is an improved version of the FG microphone and offers enhanced PFA performance and power-on reset for instant settling time. Its electrical high pass filter enabling custom corner frequencies makes the BFG ideal for use in directional applications as a matched omni-directional pair.
MM20 Series
Using Knowles’ proven high performance MEMS technology, the MM20 consists of an acoustic sensor, a low noise input buffer, and an output amplifier. These devices are suitable for applications where excellent wideband audio performance and RF immunity are required.
NR Series
The NR Series close talking microphones deliver state-of-the-art noise canceling performance. NR microphones are used as headset microphones in the most demanding communication and speech recognition environments. The NR Series microphones are available in boom microphone packages. (See the FB and PNR Series for details)
MM25 Series
Using Knowles’ proven ultralow noise MEMS technology, the MM25 consists of an acoustic sensor, a low noise input buffer, and an output amplifier. These devices are suitable for applications where excellent matching is required.
MR Series
MR Series microphones combine a conventional element with a waterproof bellows assembly. The bellows conducts sound to the element and survives 15m (50 feet) of submersion in water. They may be panel mounted, attached for boom applications and are suitable for outdoor use or repeated submersion.
WP Series
Form factors include a miniature design that can be immersed in water to a depth of one meter, and a bellows design for depths to 15 meters. The bellows design may be panel mounted, attached for boom applications and is suitable for outdoor use and repeated submersion.
