Audio Driver, Daedalon®

Many acoustic experiments require a source of mechanical motion at a known frequency. Sonometers, Kundt's tube and Chladni plates can all function more efficiently if they are driven by a precise sine wave motion. Our Audio Driver fills this common need. A sine wave oscillator combines with an audio amplifier through the frequency range of 3 Hz to 10 kHz in three ranges. A four-digit display presents the output frequency. On the low end of the frequency range, the readout is multiplied ten times so that the resolution is 0.1 Hz, important for useful accuracy at low frequency. The output waveform is a low-distortion sine wave that will drive such low impedance loads as our EG-52 Electromechanical Driver, A three-turn potentiometer on the front panel easily sets frequency. A pair of jacks on the rear panel provides a square wave output to synchronize an oscilloscope, so students may view the signal easily without jitter on the simplest oscilloscope. Provides precise sine wave motion.
