A powered mixer is a type of audio mixer that combines a mixer and an amplifier in a single unit. It is designed to provide an all-in-one solution for audio mixing and amplification in a portable package. Powered mixers are commonly used in small to medium-sized sound reinforcement systems, such as for live performances, conferences, and outdoor events. They are typically smaller and more lightweight than separate mixer and amplifier units, making them easier to transport and set up. Powered mixers can vary in size and power, with some models featuring built-in effects processing and multiple channels for connecting microphones, instruments, and playback devices. They are typically operated using knobs and faders located on the front panel of the unit, and some models may also include a built-in graphic equalizer for fine-tuning the sound.
