The CMV 551 is a large diaphragm tube amplifier body with interchangeable screw-mount M 7 S, M 8 S, M 9 S, M 14 and M 55 K capsules. An included G/B (Bajonett-Gewinde) adapter allows mounting of non ‘S” Neumann bayonet capsules (M 7, M 8, M 9). It was first released in 1955. The microphone circuit is based on a EC92 vacuum tube and output transformer. The microphone is ideal for recording solo vocals, background vocals, acoustic guitars, percussion, strings and upright basses as well as an ambience microphone. The CMV 551 is powered by the N 551 power supply. This provides the microphone with a higher voltage than required by the successor CMV 563 and therefore later power supplies won’t work within specifications. MH 55 stand mount and TS 55 table mount were available. Weight shown is for amplifier body only, without capsule. Length includes NS 67 connector.
