  • Ergonomic under-ear design – the flexible, lightweight, contoured loop hooks behind the ear for an ultra-secure, comfortable fit even for those wearing glasses
  • Detachable, field-replaceable cable with robust connector at the earset and a variety of available output terminations
  • Handles high sound pressure levels with ease
  • Wired version’s power module (AT8545) includes a high-pass filter that provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality
  •  Wirekess version equipped with cW-style locking or cH-style screw-down 4-pin termination for Audio-Technica wireless systems
  •  Comes with the AT8464x Dual-Ear Adapter Kit that converts the single-ear MicroSet to a unit that’s worn on both ears for maximum stability and comfort
  •  Beige colour (-TH) model and constructed of hypoallergenic materials

Notes on use

The BP892x requires 11V to 52V phantom power for operation, and includes a 1.4 m permanently attached miniature cable. Its free end connects to the provided AT8545 power module via a locking 4-pin connector. The connector is also compatible with Audio-Technica cW and cH type body-pack transmitters. The output of the power module is a 3-pin XLRM-type connector.

Avoid leaving the microphone in the open sun or in areas where temperatures exceed 43°C for extended periods. Extremely high humidity should also be avoided.
