Mods for the Trinity

  • Microphone PartsMicrophone Parts
    The Karma Unity and Trinity employ K67-type capsules, whose bright frequency response can be easily revoiced by swapping in an RK-47, a true single-backplate 34mm condenser capsule modeled after Neumann’s famed K-47.

Multi-Pattern Condenser Microphone

The Trinity is a 3-pattern FET condenser with a large-diaphragm capsule. It is built in a bottle-style case, with an oversized headbasket to minimize reflections around the capsule.

The grille has a domed face made of 2-layer metal mesh. Its shape avoids the use of parallel surfaces that could create standing waves between the inside of the grille and the capsule diaphragm. The capsule is shockmounted within the head of the microphone.

The capsule is a K67-style, center-terminated large diaphragm design. Both front and back diaphragms are wired to the circuit, as this is a multipattern microphone.

Three switches are located at the top of the microphone body:

  • One enables the high-pass filter (slope and corner frequency not specified).
  • One enables the -10dB pad, raising the mic’s max SPL to 140dB (distortion not specified).
  • One allows selection of the polar pattern: Omni, Cardioid, or Figure-of-8.

The mic was released in 2011.
