With nine different directional characteristics, the M 149 Tube can be adapted to very different acoustic recording situations. Like its ancestors, it is particularly suited to speech and song. This is not only due to its capsule, but also to the particularly low equivalent noise level of its modern circuit technology.
The M 149 Tube is discussed from the side. Its front is marked by the company sign and the polar pattern switch. Below the capsule, a dome scatters the sound from the upper hemisphere so that there is no disruptive interference with the direct sound components. The capsule is elastically mounted to protect against structure-borne noise transmission. The capsule is surrounded by the large microphone grille of the old M 49, which is now acoustically more open and therefore more neutral in terms of sound.
There are nine characteristics to choose from: omni, wide cardioid, cardioid, hypercardioid and figure-8, each with an intermediate position.
