Ideal for critical studio and live applications, the low-profile AT4021 offers a flat, extended frequency response, high maximum SPL and wide dynamic range. Its low self-noise is perfectly suited for the most sophisticated recording equipment. Its low-mass diaphragm improves transient response, increases response bandwidth and reduces handling and mechanical noise transfer. The microphone offers outstanding reproduction of low-frequency sounds.FEATURES- Element: Fixed-charge back plate, permanently polarized condenser- Polar Pattern: Cardioid- 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: 250 ohms- Maximum Input Sound Level: 146 dB SPL, 1 kHz at 1% T.H.D.; 156 dB SPL, with 10 dB pad (nominal)- Dynamic Range: 132 dB, 1 kHz at Max SPL- Signal to Noise Ratio: 80 dB, 1 kHz at 1 Pa- Phantom Power Requirements: 48V DC, 3.0 mA typical- Weight: 119 g (4.2 oz)- Dimensions: 144.0 mm (5.67) long, 21.0 mm (0.83) maximum body diameter- Output Connector: Integral 3-pin XLRM-type- Accessories: AT8405a stand clamp for 5/8-27 threaded stands; windscreen; protective carrying case
