Audio-Technica BP899L Low-Sensitivity Omni Lavalier Microphone
The BP899L shares its 5.3mm omnidirectional condenser design with the standard BP899, but with a lower-sensitivity capsule built specifically for high-SPL sources, a brass section, a drum kit, or a stage that just runs loud, where a standard-sensitivity lav would distort before the receiver ever clipped. It's the same low-profile, nearly-invisible-on-camera form factor, just tuned to handle more headroom.
An 80 Hz, 18 dB/octave low cut keeps handling and clothing rumble out of the signal, and it's rated for up to 146 dB SPL, six decibels more headroom than the standard BP899. It's available as a bare pigtail, or terminated for cH-style (Audio-Technica), CT4 (Shure TA4F), or cW-style (Audio-Technica) wireless transmitters, in black or beige, so it can be matched to whatever transmitter and skin tone a shoot calls for.
