The High-SPL Omnidirectional Microphone Type 4007 is a phantom powered (P48) close miking specialist with an extremely linear on-axis frequency response from 20Hz to 40kHz (±2dB). This high-performance condenser microphone has an unbeatable dynamic range of 124dB from the noise floor to 1% THD and is capable of handling up to 155dB SPL peak before clipping occurs. The Type 4007 has through its total acoustical transparency and ultra-high SPL handling capability gained a reputation as being the first choice for picking up drums, percussion and brass instruments, whenever the natural and non-distorted result is paramount. Type 4007 is, due to its linear qualities, also used as reference microphone in both microphone comparisons and acoustic test equipment.
