- The circuit can be assembled on a Vero board.
- The circuit can be powered from 9-25V DC.
- of each channel can be set using Variable resistor 10k
Transistors in the following series is enabled as a source of constant flow. By providing input audio signal on the emitter, the voltage on the emitter will fluctuate, which will cause the collector voltage also fluctuates. The amount of frequency fluctuation is comparable with the frequency of the incoming audio signal.
