The video is sent to output devices (TVs, projectors), and the audio is sent to the amp section of the receiver (and then to the speakers). They are responsible for separating audio and video signals. They process the audio received from all of the audio (and video sources), amplify audio signals, and send it to the speakers.īut they also process video signals received from all of your video equipment. More often than not, they are also combined with a DAC that allows you to connect digital audio sources (PCs, laptops, etc.).ĪV receivers can do all the things that integrated amps do, and then some more. This means is that preamp and power amp are packed inside one unit. Power amps output speaker-level signal.Ī growing number of today’s amps are the so-called integrated amps. The power amp is only responsible for amplifying the audio signal and sending it to the speakers connected to it. Preamps send a line-level signal to power amps. In a speaker system that includes both preamp and power amp, the preamp is responsible for input selection, volume control, and ‘pre-amplifying’. It amplifies it to the point when it’s strong enough for further processing, and then sends it to the power amplifier for further amplification and processing.

The first one is used to receive the low-level signal coming from the audio sources. Preamps and power amps are two separate devices. Preamp VS Power Amp VS Integrated Amp VS AV Receiver
