The DPA 4012 High Voltage Cardioid Mic. Highly regarded by engineers for its ultra high SPL capability and totally faithful reproduction of the original sound. The DPA 4012 Cardioid Microphone is a hi-voltage (130 V) condenser microphone with a linear frequency response from 40 Hz to 20 kHz (±2 dB) and an incredible SPL handling capability of 168 dB SPL peak before clipping occurs. Type 4012 is acoustically identical with the popular Type 4011-TL, but differs in the powering method which enables the 4012 to handle these extreme sound pressure levels. The off-axis characteristics of the 4012 Cardioid Microphone are totally linear, a unique quality which has taken a lot of attention to obtain. So any leakage that occurs from off-axis sound sources is still a faithful reproduction of these sounds, though attenuated according to the true first order cardioid pick-up pattern. The main features of the DPA 4012 include: Ultra High SPL Capability - 168dB Great for spot-miking on every kind of live music Often used for close-up work on acoustic guitar, grand piano, overheads, percussion, wind instruments and vocals Principle of operation: Pressure gradient Cartridge type: 19 mm (0.75 inches) pre-polarised condenser Power supply: 130 V via HMA5000 Frequency range, ± 2 dB: 40 Hz - 20 kHz Directional characteristics: Cardioid Equivalent noise level A-weighted: Typ. 19 dB(A) re. 20 µPa (max. 20 dB(A)) Sensitivity, nominal, ±2 dB: 9 mV/Pa; -41 dB re. 1 V/Pa Equiv. noise level ITU-R BS.468-4: Typ. 25 dB Capsule diameter: 19 mm (0.75 inches) Total harmonic distortion (THD): <0.5% up to 110 dB SPL peak, <1% up to 116 dB SPL peak Preamplifier frequency range: 20 Hz to 50 kHz +/-0.2 dB Output impedance: Matches HMA5000 input Cable drive capability: From microphones to HMA5000: Up to 20 m (66 ft), From HMA5000: Up to 300 m (984 ft) Microphone length: 175 mm (6.89 in) Max.
