Cardioid Condenser Microphone

The CX-112 is a large-diaphragm condenser microphone with a fixed Cardioid polar pattern, switchable pad and filter. It is the successor to the company’s CX-111, one of their first large-diaphragm condenser mics. Although both mics shared basic features, the CX-112 has a different circuit, different capsule, different grille, and different body shape.

The mic requires phantom power of 48-52 volts. The circuitry contains a DC-DC converter, with approximately 60V used to polarize the capsule. Unlike the CX-111, the CX-112’s output circuit is transformerless.

The diaphragm is a 28mm, gold-sputtered, 6 micron (.006mm) design, housed in a silicon rubber support to absorb vibration. Unlike most large-diaphragm designs, this microphone employs a contact point at the edge, rather than the center of the diaphragm; this minimizes reflections and refractions that can muddy the sound.

Supplied with:

  • mic clip (MC-112)
  • Foam lined wood case (CASE-CX)

The CX-112 was discontinued in favor of the CX-112B, which has higher sensitivity, lower self-noise, and a brighter frequency response.

The Audix CX-112 is also known as: CX112.

The mic was released in 2005.
