Collezione: Power Amplifier

A power amplifier is a device that sits between a sound source and a passive loudspeaker. Its job is to take a line-level signal and make it loud enough to fill a room or a venue with sound. Power amps can feature one, two, or more channels. For example, a mono power amp would have one channel, and a stereo power amp would have two channels. While designs vary, a standard feature on most power amplifiers is a power switch, which engages the device, and a volume control, which determines the device’s output level. 

A power amplifier is required if you want to boost a sound source's level in order to play it through a speaker (or several speakers).

Class-D amplifier is our most commonly used home amplifier, with the advantage of compactness and convenience, and the SMSL A300 with BTL mode can be used in multiple units.
