Simple 3 Line Mixer Circuit

This circuit is simplemixer circuit3 line. Many audiomixer circuithave been published but this this very simple audiomixer circuituses only one transistor. The signals to be mixed are directly coupled to the base of Transistor. Each input lines are current limited by using a 10k Potensiometer . 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. Here is a schematic mixer circuit:
