FB SERIES
FB Series are available in metallic, flexible boom styles, which utilize a wide array of
microphone elements, giving superb noise rejection and high-frequency crossover of near
and far field responses. FB’s are utilized in a variety of aircraft audio systems and radio
communication helmets. Knowles offers customized lengths and end terminations to
meet your application needs.
PNR/PWP SERIES
PNR/PWP Series are available in plastic, rigid booms, which utilize either the WP or NR
microphone element, giving superb noise rejection and high-frequency crossover of near
and far field responses. The boom microphones are utilized in a variety of aircraft audio
systems and radio communication helmets. Knowles offers customized lengths and end
terminations to meet your application needs.

No loss of performance after submersion in 1m water
Excellent environmental performance
Includes RF screening — meets the 2v/m test over the frequency
range 1 to 20 MHz
Metallic, double-spirally-wound, flexible booms which allow easy
adjustment and maintain the microphone in an optimum acoustic
position above the top lip, or close to the side of the mouth
4mm and 6mm diameter boom options
PWP utilizes the WP Series of electret, close-talking microphones with
the same acoustic characteristics as the NR series, but with the addition
feature of waterproofing to withstand submersion in 1m water
The housings of the NR Series and WP Series microphones are attached
to plastic tubing, which can be customized to a particular length
The overall PNR and PWP packages are extremely lightweight,
small and unobtrusive
