Massive sound; Superior vintage tube warmth.

The BV-1 mkII is a tube-driven, large-diaphragm condenser microphone; its predecessor has become an indispensable element in world-renowned studios and home setups due to an unheard-of combination of quality, durability, and value. The development of the BV-1 mkII was a “spare-no-expense” approach to microphone design — every single component was chosen for its sound quality. This has resulted in capacitors being used by six different boutique companies such as Solen, Nichicon, Wima, Elna, Kyocera, and Epcos. Avantone worked with many of these companies to manufacture custom capacitors just for the BV-1 mkII, as only the very best would deliver our sonic quality.

The BV-1 mkII also features a custom Cinemag output transformer designed for this microphone, as well as a handpicked edge-terminated 34mm CK12-style capsule. The culmination of these components led to a design with a huge bottom end and smooth yet airy top end. The proximity effect lends itself to a massive sound that can add body and a sense of presence to any vocals. Though the original BV-1 remains a top contender as a world-class vocal mic, the expanded versatility of the BV-1 mkII also makes for a top choice for use with percussion, piano, mandolin, brass, winds, and even guitar cabinets. The BV-1 mkII is ready for anything.

Everything you need.

The BV-1 mkII includes a suite of all the accessories you need. The power supply, just as the microphone itself,  is a “spare-no-expense” design. The ultra-high quality 7-pin cable is custom made by Sommer in Germany — this is one of the very best 7-pin cables in existence; using thicker gauge conductors for the valve heater and heater ground that ensures the vacuum tube is always being provided the best current.

A hardshell briefcase keeps everything together; even the included wood presentation box that stores the microphone itself. The included shock mount holds the microphone snug, and the included pop filter helps recording in even the toughest environments.
