Audix present a large diaphragm condenser featuring a new 33mm externally biased capsule and 3.5 micron gold sputtering.

Heart of gold

The A231 large diaphragm build features a machine aluminium body and an eye catching gold-plated brass band around it’s equator. However, this isn’t the only gold on offer - A231’s unique 33mm capsule features gold sputtering throughout its diaphragm, including areas all the way to the perimiter.

This has the effect of 25% improved responsiveness from the diaphragm during sound capture and delivers a remarkably clear sound both in for vocals and instrumental recordings.

Internally shock-mounted

Audix’s unique internal shock mount design protects the A231’s capsule against vibration and mechanical interference. This route also negates the need for a bulky external shock mount making setup faster and transport easier.

Each A231 is machined and assembled at Audix’s facility in Oregon, USA to ensure the highest rate of quality.
