Studio Maintenance and Troubleshooting
This course focuses on beginner-level studio maintenance by combining lectures with hands-on lab activities. Electronic basics are introduced, including: voltage, alternating and direct current, resistance and impedance, capacitance, inductance, and electromagnetism. The principles of grounding, power supplies, analog and digital signal types, amplifiers, speakers, microphones, switches, and transistors are described. Basic repairs and troubleshooting in the field are discussed, including soldering. Students make a mic cable, S/PDIF cable, RC and RLC circuits, and assemble a simple signal processor such as a power supply, audio input/output circuitry, direct box, or a filter. Students troubleshoot their circuits using volt- and ohmmeters, oscilloscopes, and cable testers.
