The AT4051b Cardioid Condenser Microphone from Audio-Technica consists of the company’s AT4900b-48 microphone body and the AT4051b-EL cardioid head capsule. It is suitable for field or studio use and features a cardioid pickup pattern that reduces off-axis pickup, providing isolation of the desired sound source.
The microphone’s internal transformerless circuitry reduces distortion and provides correlation of high-speed transients. There is a direct-coupled balanced output for a clean signal under high-output conditions and a strong turned-brass housing for durability. A switchable high-pass filter reduces low frequency noise, and a -10 dB pad picks up loud sound sources. The package includes a microphone stand clamp, a windscreen, and carrying case.
Features:
- 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 Audio-Technica’s stringent consistency and reliability standards
