Audio-Technica AT4051b Small-Diaphragm Cardioid Condenser Microphone

The AT4051b cardioid condenser microphone is a versatile studio performer you can employ with confidence in a wide range of professional miking applications. Ideal for professional recording as well as critical audio capture applications in broadcast, it includes direct-coupled balanced outputs, providing clean signals in high-output situations, and is totally free of the distortion associated with conventional transformer-coupled outputs. Its fast transient response contributes to its open, transparent reproduction of even the most difficult-to-capture instruments. It's fully RoHS-compliant – free from all substances that are specified in the EU directive on the reduction of hazardous substances (RoHS).

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 80Hz hi-pass filter and 10dB 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)
