Common name: Sennheiser MKH 816TU-3
Production Status: Discontinued / Vintage
The MKH 816TU-3 is a transformerless RF condenser microphone with a very narrow response pattern. Below 500 Hz the pattern is hypercardioid, becoming more club-shaped with increasing frequency. The low-impedance capsule design makes it virtually immune to high humidity and condensation.
It also exists as the MKH816P48U-3 which is 48V phantom powered (2 mA) and has a Max SPL of 128dB.
Although no longer available it is still widely revered for news and location work.
