Syncron Microphones

Microphone
Heritage

Syncron began in 1964 with a facility for mixing and making industrial film, music videos and commercials. Tired of relying on expensive microphones they decided to design and test their own.

The AU-7

The first microphone, the AU-7, was designed with standard concepts of the day, causing it to be compared with other German manufactures. The very different idea was to use batteries, thus freeing the user from a heavy and expensive power supply. The final design used a single FET and a transformer, making it a breakthrough product that gained much attention.

The S-10

The successor to the AU-7 was the S-10, designed as an answer to some of the difficulties with manufacturing the AU-7. It also used a single FET with a transformer, and incorporating another first in microphone design: the permanent battery supply for capsule polarization voltage. Up to this point, all condenser microphones needed a high voltage DC supply to polarize the capsule, thus providing the capacitor charge. In the AU-7, this was done with batteries, the S-10 used a set of encapsulated WWII bomb detonator batteries, adding up to 62 volts.
