Cardioid Condenser Microphone

AT4051b
  • The AT4051b is a Cardioid condenser microphone intended for use in professional applications where remote power is available.
  • Specially engineered to meet the most critical acoustic requirements of professional recording, broadcast and sound reinforcement
  • 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
