Heart of Gold
A231 internal circuit board and sputtered diaphragm

Wide gold sputtering 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 Shockmounted
A231 including Audix clip and case accessories

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.
