CardioidBrauner Valvet X

Cardioid Tube Condenser Microphone

The Brauner Valvet X Pure Cardioid is a Large Diagphragm, single capsule, Cardioid-only version of the Valvet.

The Valvet X is designed for intimate, close distance vocal recording.

The Valvet X differs from the Valvet in a few areas:

  • Single Diaphragm
  • Lower self-noise
  • Simplified power supply
  • Satin black finish on body, shockmount and power supply

The only difference in sound between the Valvet X and the Valvet in Cardioid mode is the slightly lower self-noise.

Mix 2009

The mic’s sensitivity was very noticeable; it is among the most sensitive microphones I’ve used. It picked up every footstep, door creak and mechanical noise. This sensitivity resulted in an unreal ability to capture every detail of a complicated vocal. However, it would also make the Valvet X very difficult to use in any environment that isn’t fairly well-isolated.

A frequency response curve is not available as Brauner does not publish this information for any of his microphones.

The Valvet X Pure Cardioid ships with: Aluminum case, VOVOX Tubelink Cable, BMS-2 shockmount, and power supply.

See Dirk Brauner describe the Valvet X:

The Brauner Valvet X is also known as: Valvet X Pure Cardio.

The mic was released in 2009.
