In the year 866, Vikings from Denmark invaded York…

The BM9 is inspired by classic Danish microphones from the 1950s and 60s, and is made here in York, so we call it The Viking.

The BM9 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, or in front of an orchestra. It has a deep, rich bottom end particularly when used close to the source, and has a large bass proximity effect. At the top end the response is smooth and detailed, as one would find in a high end vintage ribbon microphone.

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.

Custom options

Other impedances available on request at no extra charge. Because we make the transformers and assemble the microphones in-house, it is a simple task for us to modify the microphones to your requirements.

Warranty

Ribbons are warrantied for one year – with careful use they should last much longer. All other parts come with a lifetime warranty to the original owner.

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!

For our BM9s we have used 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 only make up
1% of the microphone’s weight. We chose sustainable wood for the microphone cases.

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

We have a full 30 day no-quibble returns policy so you can order and try the microphones safe in the knowledge that you can get a full refund if they don’t work out.
