Hypercardioid Condenser Microphone This versatile studio performer may be used with confidence in a wide variety of professional miking applications. Featuring direct-coupled balanced outputs for clean signals in high-output conditions, the microphone is totally free of the distortion associated with conventional transformer-coupled outputs. And its fast response to transients contributes to the open, transparent reproduction of even the most difficult-to-capture instruments. The microphone is fully RoHS-compliant – free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS). The AT4053b consists of two modular subassemblies: an AT4900b-48 body and an AT4053b-EL hypercardioid head capsule (both available separately). Additional interchangeable capsules are available in omnidirectional (AT4049b-EL) and cardioid (AT4051b-EL). Specially engineered to meet the most critical acoustic requirements of professional recording, broadcast and sound reinforcement Hypercardioid polar pattern reduces pickup of sounds from the sides and rear, improving 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) ELEMENT Externally polarized (DC bias) capacitor POLAR PATTERN Hypercardioid FREQUENCY RESPONSE 20-20,000 Hz LOW FREQUENCY ROLL-OFF 80 Hz, 12 dB/octave OPEN CIRCUIT SENSITIVITY -34 dB (19.9 mV) re 1V at 1 Pa IMPEDANCE 50 ohms MAXIMUM INPUT SOUND LEVEL 145 dB SPL, 1 kHz at 1% T.H.D.; 155 dB SPL, with 10 dB pad (nominal) NOISE 16 dB SPL DYNAMIC RANGE (typical) 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 SWITCH Flat, roll-off; 10 dB pad (nominal) WEIGHT 127 g (4.5 oz) DIMENSIONS 155.0 mm (6.10") long, 21.0 mm (0.83") maximum body diameter OUTPUT CONNECTOR Integral 3-pin XLRM-type OPTIONAL INTERCHANGEABLE ELEMENTS AT4049b-EL (omnidirectional); AT4051b-EL (cardioid) ACCESSORIES FURNISHED AT8405a stand clamp for 5/8"-27 threaded stands; windscreen; protective carrying case AUDIO-TECHNICA CASE STYLE S1
