Classic large-diaphragm reference microphone; selectable cardioid, hypercardioid, omnidirectional or figure-eight polar patterns; two-stage preattenuation pad and bass cut filter; high sound pressure level capability - up to 160 dB SPL. The C414 B-ULS is THE reference microphone for almost all comparative microphone tests and one of the most used condenser microphones in the world. It is the microphone of choice for miking up vocals, grand pianos, percussions, and any other sound sources with complex waveforms. A gold-sputtered 1-inch dual-diaphragm and Ultra Linear Series electronics combine to provide an extremely smooth frequency response. Four selectable polar patterns allow the microphone to be used for every recording technique and two bass cut filters suppress low-frequency noise. Extremely low self noise and high headroom result in a dynamic range of 126 dB, which is wider than that of digital recording equipment. Switchable 10-dB and 20-dB preattenuation pads let you record instruments with sound pressure levels beyond 150 dB SPL at less than 0.5% THD.
