The Audio-Technica AT4049b Omnidirectional Condenser Modular Microphone is designed to meet the most critical requirements for Ambience Recording both on Set or in the Field. Its omnidirectional polar pattern ensures maximum ambient pickup, while the direct-coupled, balanced output provides a clean signal even in high-output conditions, free of the distortion commonly found in transformer-coupled microphones. The Audio-Technica AT4049b’s transformerless circuitry delivers superior transient response and low-frequency distortion elimination. With a rugged, turned-brass housing, this microphone guarantees exceptional sound quality and reliable performance in any professional application. Audio-Technica AT4049b features Specially engineered to meet the most critical acoustic requirements of professional recording, broadcast and sound reinforcement Omnidirectional polar pattern provides maximum ambient pickup 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 Audio-Technica AT4049b Specifications Polar Pattern Omnidirectional Frequency Response 20 - 20.000 Hz Low Frequency Roll Off 80 Hz, 18 dB/octave Open Circuit Sensitivity -34 dB (19.9 mV) re 1V at 1 Pa Maximum Input Sound Level 145 dB SPL, 1 kHz at 1% T.H.D.; 155 dB SPL, with 10 dB pad (nominal) Dynamic Range 129 dB, 1 kHz at Max SPL Signal-to-Noise Ratio 78 dB, 1 kHz at 1 Pa Phantom Power Requirements 48V DC, 4.8 mA typical Switches Flat, roll-off; 10 dB pad (nominal) Weight 130g Dimensions 155.0 mm (6.10") long, 21.0 mm (0.83") maximum body diameter Output Connector Integral 3-pin XLRM-type Accessories Included AT8405a stand clamp for 5/8"-27 threaded standswindscreenprotective carrying case
