Sine waves are "pure" audio tones typically used to test audio
equipment. This audio oscillator kit produces sine wave
audio signals. Output amplitude and Frequency is
adjustable (2Hz to 50 KHz) with a component change. 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 VDC, PC Board size 2.25" x 2.75"
