Studio Projects T3 Vacuum Tube Microphone

T3 Vacuum Tube Microphone description:

The Studio Projects T3 vacuum tube mic is based on classic 1950’s era designs, combined with present day technological refinements. It is a versatile microphone with abundant applications in the studio from pianos and strings to guitar cabinets and saxophones. Also a serious vocal mic, the T3 will please even the most discerning ears.

The T3 is a variable pattern vacuum tube (valve) condenser microphone. It features a 1.35inch (34.5mm.) precision dual membrane capsule coupled through a minimalist tube circuit designed around the 12AY7 (6072) triode and a balanced transformer output. Pattern control is variable between omni directional, wide cardioid, cardioid, supercardioid, hypercardioid and figure of eight via a nine-position switch located on the front of the remote power supply (SPT3). This allows the T3 to be used in all manner of recording situations whether as a room mic, a single point mic for bluegrass or as a spot mic when attenuation from the side and rear is needed. The circuit design of the T3 uses as few components as necessary to prevent added noise and colouration. A hand selected 6072 "dual triode" vacuum tube is used for its low noise, sonic characteristic and reliability.
