The U7 is a Vacuum Tube Condenser Microphone powered by the supplied N7 PSU which is hand built in the USA by chief engineer, Dana Kamide, founder of Berliner USA. The U7 operates on 110/220v.
The U7 is a fixed cardioid microphone featuring a 6-micron gold-evaporated Mylar capsule which is hand built and hand tuned for maximum sensitivity, long life, superb detail and tone . The capsule also utilities a specially designed gold-plated centre element enhancing the transient response and creating a gentle rise in the upper frequencies. The body is hand-tooled from brass.
The U7 utilities a hand tested NOS GE 6072 vacuum tube chosen for its low distortion, superior signal to noise ratio and minimum sensitivity to mechanical vibration. It also employs a carefully engineered, custom wound output transformer.
