S-7C Documentation

CardioidADK S-7C

Cardioid Condenser Microphone

The ADK S-7C is a large-diaphragm transformerless FET condenser microphone derived from the S-7, a high-SPL instrument microphone that shares the 7C’s capsule and circuitry.

The S-7C differs from the two other S-7 models in tone. The S-7 provides a neutral or uncolored response. The S-7B is a dark/mellow response. The S-7C has a brilliant or bright response.

Both the S-7B and S-7C have equalization circuits built into the amplifier. That circuit is responsible for the different voicings. Except for this circuit, these microphones differ only in the color of the grille.

The S-7 mics offer a 3-position pad (flat, -8dB, -18dB) and a 3-position high-pass filter (flat, 150Hz, 100Hz).

The output circuit is balanced and transformerless.

The microphone capsule can be found in the A-6 and the other two S-7 microphones. It is a 32mm capsule with a 6-micron, 25mm diaphragm, center-terminated.

The S-7C ships in a padded wooden case with a metal “ring mount.” Available separately is ADK’s “Pro Kit,” which includes a Neutrik XLR cable, a pop filter, a foam windscreen, an elastic shockmount, and a metal flightcase (with room for the wooden mic case).

The ADK S-7C is also known as: S7C.
