From the Price Guide


The Sony C-37A is a vintage tube condenser microphone built from 1958 through the 1960s, known for its darker, richer tonality compared to the Neumann microphones made in the same era. The C-37A is particularly useful on female vocalists, where its heavier bottom end can fill out thinner voices or add some lower-octave love to sopranos. The C-37A also has a way of easily taming sibilance and harsh high frequencies with a notable dip around 1kHz and another between 6-8kHz.

More Information

Having a lower output than most other condensers, the C-37A can also be used on very loud sources like guitar amplifiers and drums without worry of clipping the mic preamp due to a crazy-hot signal. These quirky mics are capable of both directional (cardioid) and non-directional (omni) pickup by opening and closing a port to the rear of the capsule with a small screwdriver. The C-37A uses a cathode follower design and 6AU6 tubes which must be very carefully selected for noise and microphonics, and the output transformer is actually located in the power supply. The earliest models used hand-wired power supplies, later models went to PCBs and added an additional high frequency cut to pair up with the switchable bass rolloff.
