  • Overview

    Audio-Technica’s innovative BP894-TH MicroSet® offers the ultimate in low-profile, high-performance audio. The BP894-TH features a rotating capsule housing with talk-side indicator for use on either ear and perfect polar pattern placement. The MicroSet BP894-TH takes headworn microphones to the next level, by allowing the cardioid capsule to be aimed directly at the sound source. The uniform pickup pattern provides excellent rejection of outside noise, with exceptional gain-before-feedback when used with live sound systems and stage monitors.

    Delivering clear and accurate sound in an inconspicuous package, the ultra-lightweight BP894-TH hooks securely behind either ear and can be worn for hours witout fatigue. For maximum stability and comfort, the included AT8464 dual-ear microphone mount converts the MicroSet to a dual-ear-worn unit.

        You may use any wireless microphone that ends in the code "cW" which indicates the cable properly terminates with the 4 pin HRS connection used on your Audio-Technica UniPak transmitter. You may use the BP894cW-TH.

    • Q:

      Is the BP 894 compatible with an ATW-T201 transmitter?

      If not, what model of headworn is?
      Asked on 1/27/2015 by wd4aks

      1 answer

      • A:

        No it is not, the BP894cW-TH is. We offer the BP894 in both wired and wireless versions. The wireless version is the BP894cW-TH. Any of our microphones or cables whose model number contains the letters "cW" are compatible with any of our wireless systems that use the UniPak model bodypack transmitter. The ATW-T201 is a UniPak model. The "cW" refers to the connector type and the wiring scheme. All "cW' model mics and cables will have the 4-pin female Hirose connector on them.

    • Q:

      BP894cW compatibility

      Is the BP894cW compatible with the A-T UniPak transmitter and AEW-R4100 system?
      Asked on 12/17/2013 by JoelB from Alaska

      1 answer

      • A:

        Any microphone with a “cW” in the title will work with your 4000 Series. The 4000 Series bodypack transmitters used a 4-Pin HRS connection. The “cW” means the microphone has a 4-Pin HRS.

        The default color for all microphones is black. Adding a –TH denotes that color of the microphone is Beige.

        Therefore, the BP894cW and BP894cW-TH will work with the Audio-Technica 4000 Series UniPak® Bodypack Transmitter.
