Product Overview
The Audio-Technica BP898cT4 is a low-profile subminiature cardioid condenser lavalier microphone terminated with a TA4F connector for compatible body-pack wireless transmitters. Its wide dynamic range and high SPL tolerance produce intelligible, natural-sounding voice capture. The cardioid polar pattern focuses on the wearer while rejecting off-axis sound, making it well suited to stage and television talent, lecturers, and worship leaders. The discreet black housing keeps the microphone visually unobtrusive on camera and on stage.
Product Description
The Audio-Technica BP898cT4 cardioid lavalier microphone is built for focused, natural voice pickup in live and broadcast production.

The fixed-charge back plate permanently polarized condenser element provides a cardioid pattern with a pronounced proximity effect at close range that enhances the wearer's voice. This low-frequency lift drops off as working distance increases; where a less focused pickup or greater distance is needed, the omnidirectional BP899 is the recommended alternative. The 55" (1.4 m) permanently attached cable uses a urethane elastomer jacket that stays flexible and strong while resisting abrasion and moisture. An included clothing clip provides two strain-relief points that isolate the capsule from mechanical noise transferred along the cable. Two windscreens are supplied, each with a clasp that locks it to the microphone so it stays in place during critical moments such as sporting events. The TA4F termination connects to compatible body-pack wireless transmitters that accept a 4-pin TA4F input. You can review this lavalier and related models in the BP898cT4 listing at Creation Networks.
