6 FAQs about [Capacitors for power amplifiers]

What are electrolytic capacitors used for?

Within the audio realm, electrolytic capacitors are often found in power supply units, filtering out unwanted noise and providing a stable voltage. They’re also used in amplifier circuits to couple and decouple signals. One of the primary advantages of electrolytic capacitors is their high capacitance value per unit volume.

Why do audio amplifiers have capacitors between stages?

In a audio amplifier, or anything else that doesn't need to work at DC, it is common to have capacitors between stages to block DC and allow each stage its own DC operating point. You have said that ..quiescient output should be around 6 V. How can I calculate this?

Why do power amps have a capacitor value?

Input, feedback and DC supply paths in power amps and preamps will always have a defined resistance, and the capacitor value is chosen to ensure that the lowest frequency of interest (typically 20Hz) is passed without attenuation.

Are power amplifier coupling caps electrolytic?

Power amplifier coupling caps will generally be electrolytic types, because the values involved are large and film capacitors are simply too bulky and expensive. While many people don't like using electros, far more serious problems will occur if the feedback cap were to be a film type.

What types of capacitors are used in audio equipment?

Ceramic capacitors are another popular type of capacitor used in audio equipment. These capacitors use a ceramic material as the dielectric, providing a reliable and consistent performance over a wide range of frequencies. Ceramic capacitors are often used in combination with other capacitors to provide a more complete filter response.
