The 3532-SP is a complete state-of-the-art A-B Stereo Kit with two 4041-SP Microphones. They are carefully matched within +/-0.5 dB on both frequency response and sensitivity in the entire frequency bandwidth. This A-B stereo kit is the ultimate choice for the demanding engineer and audio purist who emphasizes clarity, openness, precision, low self-noise and high sensitivity. The kit is designed for a broad range of uses; for classical, jazz and folk genres, grand pianos, guitars, overheads or close-miking drums, choirs, strings, wind instruments and much more. You get a bright and transparent sound quality with lots of headroom. With its soft boost, which is present on-axis, and gradually goes towards linearity off-axis, these omnidirectional microphones can be angled to use as a natural equalizer. These mics are a part of the Recording Microphones Series. The diaphragm and housing are both made from stainless steel. This gives the capsule a unique immunity against ambient temperature variations. The precision-made back plate is placed in a quartz insulator for maximum electrical stability. This gives the MMC4041 Large Diagram Capsule a unique sensitivity of up to 90 mV/Pa. The 4041-SP has a frequency response from 10 Hz to 20 kHz with a 4-6 dB soft boost around 8 kHz. Furthermore, the MMC4041 Large Diaphragm Capsule has extremely low self-noise of 7 dB(A) with the MMP4000-S. It also has enhanced SPL handling capability of up to 144 dB SPL before clipping occurs.
