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 multiple high- and low-pass filters. 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 is visually identical to the C1 capsule; it is a K67 style, although the rear backplate is clear plastic rather than brass, and the rear diaphragm is not metallized. The diaphragm diameter is ~27mm, while the O.D. of the capsule is 34.1mm.
In the sample mic we inspected, the backplate is polarized at 60VDC. Curiously, the front diaphragm is polarized at 3VDC, resulting in a net 57V polarization voltage.
The CS1 has a fixed Cardioid polar pattern.
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, a hardshell carrying case, and spare elastics for the moutn.
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.
