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
The T3 is a variable pattern vacuum tube (valve) condenser microphone. It features
our 1.35? (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 coloration. A hand selected 6072 “dual triode”
vacuum tube is used for its low noise, sonic characteristic and reliability. The T3 provides
warm transparent sound associated with large capsule tube microphones and it is the
absolute stand-alone value in its price class.
As a result of uncompromising dedication and advanced production capabilities,
Studio Projects will continue to broaden the range of quality pro audio microphones &
electronics for today’s recording environment.
