Designed to be equally at home in front of a guitar amp or a orchestra, the Extinct Audio BM9 brings you the best combination of vintage tone and modern utility. The BM9 is a versatile, low noise ribbon microphone, with strong output, rich bass and clear, detailed top end.

The BM9 is made entirely in the UK*. Metal parts are machined and plated in England, and the transformers and assembly are performed at our facility in York.

Quality control is paramount with ribbon microphones, which is why every ribbon is fitted and tuned by Dr. Stewart Tavener, an engineer who has worked on thousands of vintage microphones.

The BM9 is supplied with a solid wood box.

Mechanical parts carry a lifetime warranty to the original owner. Ribbons are warrantied for 1 year from date of purchase, but with care should last many years.

Technical specs:

  • Pickup pattern – True figure 8
  • Impedance – 300 ohms at 1 Khz.
  • Other impedances from 30 ohms to 600 ohms available as custom order
  • Weight – 355 grams. (microphone only)

    …a superb, hand built, ribbon microphone, in the finest tradition of Yorkshire craftsmanship and engineering. It produces an extraordinary level of fine detail. The low end is rich and full. It is a joy to work with…. I still can’t help going ‘Oooo shiny’ every time I open the lid of the box!
