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
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.

The earlier model C 3000 has had a large fan club in the project studio and home recording worlds for years. For the new C 3000 B, AKG designed a special 1-inch large-diaphragm transducer that closely approximates the vibration performance of top-class studio microphones, but can be made at much lower cost.
Due to its surface area and special capsule tuning, the C 3000 B large-diaphragm transducer produces an exceptionally pleasing, smooth sound. Unlike in the C 3000, the switchable 10-dB preattenuation pad immediately follows the transducer in the signal path, thus increasing the C 3000 B\'s SPL capability by a true 10 dB. Loud sound sources are therefore no problem.
An acoustically optimized cardioid polar pattern makes the C 3000 B an excellent choice for both recording and live sound applications where high gain before feedback is paramount.
