AUDIO OSCILLATOR

Sine waves are "pure" audio tones typically used to test audio equipment. This audio oscillator kit produces sine wave audio signals. Output amplitude is adjustable. Use this kit to learn the "signal injection" method of audio-circuit troubleshooting, or connect two or three together to produce complex audio signals such as DTMF (Dual-Tone Multi-Frequency) "phone tones." Connect to the audio amplifier (EBAA-1) and hear the sine wave tones. Power requirement +9 volts DC, size 2.25" x 2.75"
