A microphone built to work. The Beyerdynamic M 640 N is a compact vintage dynamic microphone designed for practical, everyday professional use. It reflects Beyerdynamic’s utilitarian engineering philosophy of the time: solid construction, predictable performance, and a sound that fits easily into real recording situations. As an instrument microphone, it proves to be reliable, versatile, and surprisingly adaptable.

BUILD & DESIGN
The Beyerdynamic M 640 N features a compact, robust metal housing designed to withstand demanding studio, broadcast, and live environments. Its straightforward construction prioritizes durability and ease of placement, allowing it to fit almost anywhere without getting in the way.

The microphone uses a small Tuchel connector, keeping it true to its original format. With the appropriate cable or adapter, it integrates reliably into modern setups while preserving its original character.

SOUND CHARACTERISTICS
The M 640 N is a very capable instrument microphone with a balanced and controlled sound. The low end is tight and practical, the midrange focused and usable, and the high frequencies smooth and unobtrusive. It does not exaggerate or hype, which makes it easy to place on a wide range of sources.

It works particularly well on guitar cabinets, percussion, amps, and general-purpose instrument duties. A true workhorse microphone — robust, predictable, and effective — that simply does its job without drawing attention to itself.
