BlumleinExtinct Audio Valkyr

Blumlein Ribbon Stereo Microphone

The Valkyr from Extinct Audio, also known as the BMx2, is a stereo version of the company’s flagship BM9.

It features the same 1.8-micron ribbons and custom-wound transformers. The ribbons are precisely matched, with one mounted at a 90° rotation relative to the other, enabling single-mic Blumlein stereo recording.

As with all Extinct Audio mics, the ribbons and transformers are made in-house.

Martin Mitchells Microphone Blog

Valkyr captures an intimate and detailed stereo image conveying the exact positioning of the performers… The balance across the frequency range is excellent and requires absolutely nothing in the way of post-production EQ… For accurate ‘real stereo’ recording, the Valkyr provides an extremely cost effective, and unobtrusive solution… The audio arriving at the front of the mics is phase coherent and the rich acoustics are also accurately reproduced, capturing a clear impression of the building.

The Valkyr ships with a 4-meter XLR5 cable, a Fenrir vibration mount, a stereo breakout box (XLR5 in, 2x XLR3 out), and a molded travel case.

The microphone includes a one-year warranty on the ribbon and a lifetime warranty to the original owner on all mechanical parts.

The Extinct Audio Valkyr is also known as: BMx2.
