22 251

Vacuum Tube Large Diaphragm Condenser

The Peluso 22 251 Tube Microphone is styled after the legendary vintage ELA M 251.
Produced for Telefunken GmbH by AKG from 1960 to 1965, the ELA M 251 remains one of the rarest and most coveted of vintage microphones. While the 251 did not evolve very far from the C 12 there are a few key differences. They both employ a double-sided 34mm dual-backplate, edge-terminated gold-coated Mylar capsule and a 6072A glass triode tube. They both employ the T/14 output transformer. The circuitry differs in the way the tube grid and cathode are handled. This gives the 22 251 about 7 dB more gain than the P-12. Additionally, the head grille of the 251 is a little larger than the 12, altering the frequency response. Whether you choose the Peluso 22 251 or the P-12 you will have a microphone with the clarity, openness and top-end 'air' from these vintage legends!

        Please note, some of the videos included here are using the the MSC - Mid-Side-Custom version of our 22 251.  The MSC microphone is identical to the standard 22 251, but with an added end-address cardioid capsule. This configuration is ideal for capturing a vocalist-instrument combination in a single phase coherent mic giving independent editing control over the vocal and instrument.

        RECording Magazine Logo

        There is something inherently 'right' about the sound of large-format, large-diaphragm valve mics when it comes to recording vocals, and the 22 251 delivers a lovely bright, clear sound that retains just the right amount of warm, harmonic richness to complement the source nicely, whether a male or female voice.
        -Hugh Robjohns, Sound On Sound 5-2010


        Headliner Magazine Logo

        The Peluso is very round and full. It sounds great on acoustic guitar and the three voices I tested it on. Short of the real 251, this is a great mic on it’s own and is very reminiscent of its older and more distinguished cousin. I think the world is going to stand up and take notice of this microphone
