Week #1: Audio amplifier Week #2: Microphone circuit The audio amplifier project is more difficult and time-consuming than the microphone pre-amp, so part of week #2 may be used to finish the audio amp. All breadboarding and testing can and should be done in lab. Soldering and hardwiring can and should be done outside lab.

For audio amplification applications, each channel can output to one speaker. The voltage gain of this system is 12. All of the power transistors are heatsinked to withstand the heat generated while amplifying the current in the output stage. The amplifier can easily operate in ambient temperatures of 35 °C without fans. Figure 1A. Circuit Diagram
