Peluso Microphone Lab P12
Multi-Pattern Tube Condenser Microphone
The P12 is Peluso’s version of the AKG C12. It is a large-diaphragm tube mic with a CK-12-style capsule.
The capsule is Peluso’s CEK-12, a 34mm dual-backplate capsule that is edge-terminated like the CK-12. It uses two 28mm diaphragms made of 6-micron Schneider Mylar, sputtered with gold.
The tube is a 6072a, tested by Peluso on original AKG tube-testing equipment. Only the lowest-noise 6027a’s are selected for use in microphones.
The tube is mounted in an inverted fashion in the P12, to minimize the length of the point-to-point wiring from the tube to the capsule.
The P12’s transformer is built by Tamura to match the performance specs of the AKG T14 transformer, based on AKG design papers provided to Peluso by AKG engineers.
Peluso’s “22 251” and P12 share most components — the capsules are identical (CEK-12), as are the tubes (6072a) and transformers (T14 style, by Tamura). The amplifier circuits are slightly different, as are the size and shape of the headgrille. The latter is responsible for most of the sonic difference between these microphones, because the capsule in the 22 251 is about 1/2'' farther from the grille and therefore will never produce as much LF boost due to proximity to the source as the P12 can.
Like all Peluso microphones, the P12 is built in the USA, using parts sourced internationally. The frequency response for every finished microphone is measured and stored at the factory, and is available upon request.
The Peluso Microphone Lab P12 is also known as: P-12.
