    A versatile mic suitable for critical recording, broadcast, and sound reinforcement.

    The Audio-Technica AT4051B Cardioid Condenser Microphone is ideal for professional recording and critical applications in broadcast. Featuring direct-coupled balanced outputs for clean signals in high-output conditions, the AT4051B microphone is totally free of the distortion associated with conventional transformer-coupled outputs. Its fast response to transients contributes to the open, transparent reproduction of even the most difficult-to-capture instruments.

    The AT4051B mic is fully RoHS-compliant—free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS). The AT4051b consists of two modular subassemblies: an AT4900b-48 body and an AT4051b-EL cardioid head capsule.

    Recommended uses of the AT4051B are acoustic guitar, percussion, drum overheads (mainly for cymbals), and live-sound instrument recording where rear-cancellation is required.

    • Specially engineered to meet the most critical acoustic requirements of professional recording, broadcast and sound reinforcement
    • High front-to-back rejection ratio—cardioid polar pattern improves isolation of desired sound source
    • Direct-coupled, balanced output results in a clean signal even under high-output conditions
    • Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients
    • Switchable 80 Hz hi-pass filter and 10 dB pad
    • Rugged turned-brass microphone housing for enduring dependability
    • State-of-the-art design and manufacturing techniques ensure compliance with A-T's stringent consistency and reliability standards
    • RoHS-compliant—free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS)

    Comments about Audio-Technica AT4051B Cardioid Condenser Microphone:

    I reasearched small condensers for a month before deciding to purchase the AT4051b. I was torn between it and a Neumann KM184. A lot of reviewers noted the KM184 is hyped in high freq. I listened to a lot of audio samples that seemed to confirm this. I decided to go with the AT which was touted as being much more flat. I have a Rode NT1a that I have used in all my recording. The AT was a quantum leap in sound quality. Now my mando and guitar both have a luscious warm and woody sound. Highs are great but not hyped.. just natural. These AT4051's are awesome for acoustic instruments!
