Oktava ML-16

MoMics note

There are two distinct versions of the ML-16. The earliest models had a narrower, longer ribbon and different pole pieces that are similar to the earlier ML-15 model. These are typically a beige colour. Our earliest ML-16 is dated 1962 and the ribbon measures 36mm long and 2.1 mm wide. This is shown on the left in the internal photographs above.

Later microphones are usually a khaki green colour and have a wider ribbon which is 30 mm long and 2.6 mm wide. The examples in our collection with this geometry are dated 1971 and 1972. This is shown on the right in the internal photographs above.

Many ML-16 microphones have internal blast screens of different types. . This might be a piece of tuffnol or bakelite glued in front of the ribbon, or, more commonly, a pair of brass baffles on each side of the motor. This is in addition to wire grill and a layer of fabric. These elements protect the ribbon and ensure they were durable when used for speech, but for recording musical instruments, the mics undoubtedly sound better without the baffles.
