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.

In many amplifiers, the protection LED will only light if the power supply is working and the audio circuit trips one of the protection circuits (over-current/DC offset). If the power supply is blown, it's generally not possible for the audio circuit to trip the protection circuit and therefore the protection LED will not light.
