Model 113 Touch Controlled Voltage Source

A touch-sensitive keyboard consisting of four circles, each of which is divided into five segments (1 central and 4 peripheral). Touching a segment causes an increase in voltage at a corresponding output. Switch-selected time constants provide extended attack and decay times. 20 potentiometers control the output voltages independently of or in conjunction with the keyboard.

Used with the Model 120 distributor, the Model 113 enables a performer to manipulate the origin of sounds within a room. Used with Model 310 lamp drivers, spatial control of room lighting may be realized.
