FAQ
A power amp, or power amplifier, takes a line-level audio signal from a preamp, mixer or other source and amplifies it to drive passive speakers. In a separate-component audio system, the preamp handles source selection and volume control, while the power amp supplies the speaker-level signal.
A standalone power amp handles amplification for passive speakers and typically relies on a separate component for source selection and volume control. An integrated amplifier combines preamp and power amp functions in one unit. Some integrated amplifiers also include digital inputs, a phono input or wireless connectivity.
These classes describe how an amplifier’s output circuitry operates. Class A output devices conduct throughout the audio signal cycle, while Class AB uses output devices with overlapping conduction periods. Class D uses rapidly switching output circuitry. The class describes the circuit approach, not a ranking of sound quality.
Common audio inputs include unbalanced RCA and balanced XLR connections. Professional audio models may also have TRS inputs. Speaker outputs can include binding posts or locking speaker connectors. Some power amps include a trigger input that lets a compatible preamp or receiver control their power state.
A stereo power amp has two amplification channels, commonly used for left and right speakers. A monoblock has one channel, so a stereo setup typically uses two monoblocks. A multichannel power amp provides several channels in one unit and is commonly paired with a home theatre processor or a receiver with preamp outputs.
