Common name: Neumann USM 69 i

Production Status: In production

The USM 69i is the second microphone for coincidental stereo (X-Y, M-S and Blumlein) with transistorized electronic, manufactured by Georg Neumann Gmbh. It was released in 1979 and it is still produced today. It belongs to the “fet 80” series and is a descendant of the SM 69 fet, manufactured from 1970 to 2010. It has the same external shape but it is taller, because the microphone incorporates a rotary switches for pattern control. Only five polar patterns are available instead of nine as in the SM 69 fet. The capsules and head grille are the same. Two K 870 capsules (a K 67 version suitable for the first U 87 series) are housed inside a 48 mm diameter head grille, the upper one can be rotated by 270 degrees. The directional patterns can be selected separately and the two built-in microphones operate independently of each other. No special PSU is necessary and the two separated circuits can be powered with a special cable.
