This premium electret condenser microphone is engineered to meet the most critical acoustic requirements of professional recording, broadcast and live sound. The AT4041 cardioid studio condenser microphone features a smooth, extended frequency response with a slight rise in the high-frequency region and a transformerless output for very high SPL-handling capability. A unique combination of audio excellence and moderate cost, the AT4041 is a rugged microphone housed in a case of turned brass with black chrome plating for durability and low reflectivity. The element back plate holds a fixed charge and has been aged to provide energy stabilization. The surface of the back plate is precision milled to ensure maximum charge linearity, resulting in a reduction in both frequency response peaks and diaphragm break-up distortion.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: -36 dB (15.8 mV), re 1V at 1 Pa- Impedance: 100 ohms- Maximum Input Sound Level: 145 dB SPL, 1 kHz at 1% T.H.D.- Dynamic Range: 121 dB, 1 kHz at Max SPL- Signal to Noise Ratio: 70 dB, 1 kHz at 1 Pa- Phantom Power Requirements: 48V DC, 3.2 mA typical- Switch: Flat, roll-off- Weight: 4.2 oz (120 g)- Dimensions: 6.28 (159.5 mm) long, 0.83 (21.0 mm) body diameter- Output Connector: Integral 3-pin XLRM-type- Accessories: AT8405a stand clamp for 5/8-27 threaded stands; AT8159 windscreen; protective carrying case
