Manual

C1
The C1 is a high quality true condensor pressure gradient
microphone with an FET impedance converter. It is a large
diaphragm microphone with a cardiod polar pattern and
a 6 um capsule for thick natural reproduction of the vocal and
instrument range. The C1 uses a transformerless circuit, that
features extremely low noise and wide dynamic range. The
C1’s polar response is very linear over a wide incidence angle.
Signals coming from the side are reproduced accurately
and without any coloration. The microphone capsule is
immune to typical interference and outside contamination.
The microphone is supplied with a shock mount, windscreen
and heavy duty road case with locking latches.

USING STUDIO PROJECTS
MICROPHONES
Studio Projects is a high quality true condensor pressure gradient microphone with FET impedance con-
verter. (NOTE, this is NOT an electret microphone).
The capacitor element is manufactured to the classic ‘center electrode’ design which provides smooth
extended frequency response without low frequency boominess. Quality is further enhanced by using
dynamic feedback actually at the capacitor element. This original technique eliminates distortions which
can occur when using this type of microphone for high volume levels. The capacitor membrane is microfine
6 um ‘mylar’ with gold sputtering, voltage polarized by phantom power.
The polar response is linear over a wide incidence angle, so signals coming from the side are reproduced
without coloration. All models are supplied with an elastic shock mount system. Although the microphones
are not particularly susceptible to sounds transmitted through the case, it is advisable to use this shock
mount wherever possible.
The C1 & C3 is more sensitive to sounds from the front than from the rear when used in the CARDIOD pat-
tern. The front of the microphone is indicated by the Studio Projects logo. To get the best quality, be sure
the sound source is in line with the front of the microphone. For vocals, a ‘nylon’ pop shield is recom-
mended. AVOID using foam plastic ‘pop’ shields. These may be effective at stopping ‘popping’, but can also
affect the working of the microphone so the sound is dulled. To get that classic early capacitor microphone
sound, the singer should sing across the front of the microphone at a distance of 12" to 24" from the micro-
phone.
The C3 and T3 are Multi-Pattern microphones that provide Cardiod, Omni, and Figure Eight patterns. These
multiple patterns allow the user more flexibility in their recordings. The Omni pattern picks up sounds uni-
formly from all over the capsule, while Figure 8 rejects sounds from the sides (left/right). Using these patterns
correctly will give the user a wide variety of recording applications. The T3 offers 6 variable patterns
between the three patterns for even more flexibility of nine total patterns.
ORIGINS AND MANUFACTURE
Studio Projects Microphones are manufactured in Beijing, China by 797 Audio to a specification created
by Studio Projects, Torrance, California. All Studio Projects microphones are inspected and tested at
the factory, then inspected and tested again at PMI Audio Groups facility prior to shipping. Studio
Projects microphones meet the requirements of electronic equipment sold both in the USA, Canada,
and the European Union.
