Gertsch Singer BRT1522U

The programmable BRT1522U Ratio Transformer is an audio frequency, inductive voltage divider which provides an output voltage with a precise ratio to an input voltage. Receives binary coded digital information to set up a six decade output voltage ratio. Frequency range: 200 to 10,000Hz. Designed for remote control only - all control signals, input reference voltage, and the output ratio voltage are supplied through a single 34 pin, Winchester connector.
