Studio Projects cs1

Cardioid Condenser Microphone

Studio Projects’ cs1 is a transformerless FET condenser microphone with a large-diaphragm, fixed-cardioid capsule.

Onboard switches provide access to a 5-way pad and 9-way filter. The pad options are: flat, -5dB, -10dB, -15dB, -20dB.

There are four high-pass filters (aka “low cut” filters), attenuating the signal by 6dB at a selectable frequency: 50Hz, 75Hz, 150Hz, 300Hz.

Somewhat unusually, there are four low-pass (“high cut”) filters, attenuating the signal by 6dB at a selectable frequency: 3kHz, 5kHz, 7kHz, 15kHz.

The capsule has a 27mm diaphragm and is likely single-sided. The mic has one pickup pattern (cardioid).

The amplifier circuit is a low-noise design, measured at 10dBA self-noise. The output circuit is transformerless.

As of April, 209, the mic’s street price is $250-$400 — less than half its MSRP. It ships with the “halo” shockmount, a foam windscreen, and a hardshell carrying case.

For more information, see the reviews of the cs5, which is the same mic with a dual-diaphragm, multipattern capsule (link in sidebar).

The mic was released in 2007.
