A mixer is commonly used to blend live audio from a band. Mics, guitars, drums, organ, special effects, and other instruments all need to be amplified and fed into the PA speakers. The mixer is used to condition these signals, as well as establish their relative volumes and feed them to the power amplifier.Jul 2, 2021
What is difference between mixer amplifier and power amplifier?
The power amp takes the output of the preamp and delivers the signal with enough power to drive the speakers. A mixer is a kind of preamp, it is actually many preamps all in the same enclosure. But a mixer does not select only one source, it mixes multiple audio sources and feeds the combined output to the power amps.
What is a PA amplifier used for?
A PA amplifier is usually an audio amplifier designed to accurately amplify sound, esp. of the human voice, and drive loudspeaker(s) so that this sound can be heard better than if it were unamplified - for example in a large classroom, or in an airplane, or in an auditorium.
Do I need a power amp for my mixer?
If you want to use the mixer just for recording, a power amplifier is not necessary. If you want to use it for a live concert or the like to drive speakers then you need a power amplifier whether it is in the mixer or separate. Powered mixers are heavier and deeper than unpowered mixers.

Is a power amp necessary?
You don't need an amplifier. An amplifier's job is to increase the power output of your source to the level you want, and if whatever you're using to listen to music can do that on its own: a lack of power isn't one of your issues. You can stop reading here and go enjoy your audio adventures!
What does a PA mixer do?
Mixers let you connect and control levels that are received from microphones and sent to speakers. Their main function is to bring microphone and instruments levels up to line level and then balance the mix before sending it to the loudspeakers. Learn more about how to set up a mixer.
What is a mixer used for?
A sound mixer can also be known as a mixing console or more commonly as an audio mixer. This is an electronic device used for mixing, balancing and combining different sounds and audio signals, sources like microphones, instruments, and synthesizers or previously recorded audio.
Does a power amp make a difference?
It's possible for two amps with slightly different wattage ratings to sound different, but all things being equal, they won't produce a different volume. A better amp will make your speakers play louder and sound better, but it won't make bad speakers sound like good speakers.
Do mixers have built-in amps?
Powered mixers are analog mixers with built-in power amplifiers. For this reason, sound can be played with the mixer directly connected to speakers.
Do I need a mixer for a PA?
Band or music group Channels add up fast, so an ideal mixer is one that has enough. In this case, you'll likely need a larger mixer with additional channels for mics, aux sends for stage monitors, and a stage snake to make setup easier.
Is a PA system the same as a mixer?
The mixer is a part of a PA system. You have various inputs to the mixer, for instance microphones or line instrument signals. Those inputs are mixed and the signal sent to a power amplifier, and from there to the speaker/s. Some mixers have integrated power amplifiers and the same goes for speakers: powered speakers.
Do I need an amp if I have a powered mixer?
A powered mixer contains built-in amplifiers to boost the signal from stereo components and musical instruments so a pre-amp is not needed to drive the equipment. When connected, the mixer can then be used to shape the sound qualities of the various audio components.
What is mixer amplifier?
An amplifier, or amp, is a device that modulates the amplitude of a sound signal. A mixer is an electronic device which is often used for changing the quality and the levels of audio signals. It is also known as a mixing console, an audio mixer, or a soundboard.
Is a mixer a power amplifier?
Powered mixers are analog mixers with built-in power amplifiers. For this reason, sound can be played with the mixer directly connected to speakers. In cases where the same equipment is always connected, powered mixers can be used by simply turning the power on, so operation is simplified and convenient.
Does power amp affect sound quality?
Amplifiers ideally amplify audio signals linearly and, therefore, do not technically improve or worsen sound quality. However, less-than-ideal amplifiers, amp settings and amplifier-speaker combinations may worsen sound quality. Amps are nevertheless needed to drive speakers and headphones properly.
Does amp power matter?
The rated power of a speaker is simply the maximum power it is claimed to be able to handle without damage. So even by layman's logic, you could hook up a 200W amp to a 100W pair of speakers, have the volume up to half way, and all will be fine.
