audio technica / BP899LcH

An omnidirectional, low-sensitivity, compact lavalier microphone for wireless systems, compatible with the Digital 3000/5000/6000 Series, designed to capture performers' voices in musical theater and similar applications with exceptional clarity and detail.

A low-sensitivity model designed for musical theater, stage performances, and drama, providing highly accurate voice pickup with minimal distortion.
Features a low-profile design with a 5.3 mm diameter, ideal for applications where visual discretion is required.
Utilizes a urethane elastomer cable with a dual-spiral shield wire, offering excellent flexibility, durability, abrasion resistance, and moisture resistance.
An open diaphragm structure and protective mesh guard against sweat and humidity, ensuring superior frequency response and overall performance.
Included resonance cap enhances vocal clarity.
Robust metal construction effectively shields the internal circuitry from external electromagnetic noise.
Signal lines use a highly durable CuSn (copper-tin) alloy for improved corrosion resistance and long service life.
Comes with a windscreen designed to stay securely in place during use.
Includes a tie clip with 360-degree rotation and 16-step angle adjustment, as well as dual strain relief points for easy cable management.
