The Extinct Audio BMP (The Viking) is a versatile low noise studio ribbon microphone. The BM9 comes supplied with hard-tail mount and box. Made in the UK Extinct audio offer high quality ribbon mics at an affordable price.

Extinct BM9

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

Quality control is paramount with ribbon microphones, which is why every ribbon is made, fitted and tuned by Dr. Stewart Tavener, who has worked on thousands of vintage and new microphones. The BM9 is made in the UK*. All the metal parts are machined and plated in England, and the transformers are wound and the mics assembled  at our facility in York.

The BM9 is supplied with a solid wood box and hardtail mount.

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.

BM9 Features

The BM9 from Extinct Audio is a general purpose bi-directional ribbon microphone, with a symmetric figure-8 pickup pattern. It is designed to be equally at home in front of a guitar amp, above an orchestra, and everywhere in between. It has a deep, rich bottom end particularly when used close to the source, and has a large bass proximity effect. At the top, the response is smooth and detailed, as one expect to would find in a high end vintage ribbon microphone.

Aesthetically, the BM9 is inspired by classic Danish microphones from the 1950s and 60s, but contains numerous technical innovations which bring its performance, noise floor and output level ‘bang’ up to date.

Deep-field magnets

The Viking utilises a wide, long ribbon in a strong magnetic field to give a strong output with low noise floor. The deep-field magnets ensure linear performance as the ribbon moves from front to rear. Vertical grill slots of different size reduce diffraction and improve rejection from the sides of the microphone. All this adds up to a deep, rich tone with an amazing degree of clarity from a ribbon microphone.

The Sonic Temple

Every Extinct Audio ribbon is sonically tempered for durability and extended life. This involves subjecting the microphone to audio frequency vibrations, which harden and strengthen the aluminium ribbon. The custom-wound permalloy core transformers are designed and made at our workshop to ensure high efficiency and low noise over the full sonic range.

Built in Yorkshire

All the mechanical parts are machined in the UK, and the microphones are assembled here in our workshop in York. Each ribbon is hand-fitted and tuned by Stewart, who has over a decade of experience repairing and building thousands of ribbon microphones.

Built for the future

Good quality studio microphones have very long lives and may be in use for several decades if cared for and serviced occasionally. We have seen ribbon microphones come in for service that were made in 1927, and sincerely hope that our microphones will outlive their owners!

We use recyclable or sustainable materials where possible. 99% of the microphone is made of metals – brass, steel and aluminium, all of which can be recycled. Plastic parts make up just 1% of the microphone’s weight. The microphone boxes are made from sustainable ash wood..

We re-use cardboard boxes and other packing materials where possible for shipping the microphones.
