The DPA 3511 Cardioid Standard Stereo A-b Kit. Superb matched pair of 4011-TL Cardioid Microphones with important accessories. The DPA 3511 is a complete stereo kit for a broad range of recording applications using two 4011-TL Cardioid Microphones, carefully matched within +/- 1 dB on frequency response, sensitivity and self-noise. These cardioids are exceptionally linear in their frequency response - also off axis, giving you the natural experience. Several standard set-ups such as ORTF and XY are possible. The 4011-TL mics handle very high SPL and will therefore allow close placement as well as more distant. Often used for piano recordings of jazz or pop with a placement closer to the hammers or as overheads for drums. The kit includes 2 windscreens, 2 very effective shock mounts, a precision-crafted stereo boom for secure mounting of microphone pairs for A-B stereo recordings and a spacer to allow XY or ORTF stereo set-ups on the boom. The main features of the DPA 3511 include: High SPL Capability - 158dB Great for spot-miking on every kind of live music Often used for A-B stereo recordings (pair), 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 in) pre-polarised condenser Power supply: 48 V Phantom power 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: 10 mV/Pa; -40 dB re. 1 V/Pa Equiv. noise level ITU-R BS.468-4: Typ. 25 dB Total harmonic distortion (THD): <0.5 % up to 110 dB SPL peak, <1 % up to 116 dB SPL peak Output impedance: <200 Ohm Cable drive capability: Up to 100 m (328 ft) Microphone length: 175 mm (6.89 in) Max.
