“What a beautifully rich-sounding microphone. The A231 sounds like it is voiced more like great FET mics of the past with a rich neutral totality and a gentle, firm upper-mid presence. There is absolutely zero bite, sibilance or sizzle on the top end, and my favorite part of the A231 is its extended, full proximity effect. The A231 is a mic that begs to be close to a source and would do well on upright bass and cello, and could be a great choice on a bass cabinet, outside, yet close up on a kick drum, and a pair would be nice for classic drum tones in a Glynn Johns overhead set up.
Where this mic really shines is on vocals and spoken word. In both cases, it has a low-end fullness that a good singer and speaker could really work to their advantage.”
