Is there a difference between a power amplifier and a mixer amplifier, and how do you know which type of amplifier you need for your commercial sound system?
On today’s Pro Acoustics Tech Talk, Nathan is talking all about power amplifiers, mixers, and mixer amplifiers. He will be defining each type as well as explaining the differences and how they each work.
Audio Power Amplifier
- An audio amplifier is an electronic amplifier that amplifies an input signal up to a high enough wattage to where it can drive speakers. This will take an audio signal and transform that into electrical wattage. That wattage will then drive the speaker to make the paper cone move to generate sound waves.
Audio Mixer
- An audio mixer is where you plug in lots of individual input sources so that you can control and adjust the actual audio signal. Some mixers are designed more for pro audio and some more for commercial audio, but the idea is they all allow you to adjust the audio signal and also match it to the appropriate output to drive an amplifier.
Mixer Amplifier
- A mixer amplifier combines the characteristics of a mixer and an amplifier. Mixer amps not only have amplifiers built-in but can also control multiple input sources. You can set the volumes as well as adjust bass and treble and things like that from your mixer amplifier. What's important here is not only does it allow for multiple input sources, but it makes sure that whatever device you're connecting is driving the amplifier with the appropriate signal you need to make sure you get the wattage required.

hi, I've just bought a mixer for my band, but the sound is pretty low, so I was looking to find an amplifier for it. what kind would I look for ? we have two mics, drum, bass and guitar.
thank you sir
Thanks for watching Ryan!
Thanks for the video. I had a question though. I currently have a 'Harbinger Level 7' mixer with 2 PC's hooked up to it via the Ch 2/3 and Ch 4/5 which lead into the headphone out via a 1/4inch stereo to 1/8 inch stereo cable. When I turn the audio levels up I get a lot of noise, and hear I could hook it up to a powered amplifier somehow to counteract that. I am looking to buy a Shure SM7B microphone to hook into the audio mixer and then into my main PC, but I have no idea on where to start to connect them all together. Any help would be appreciated, thank you.
Hi Matt,
Thanks for watching! We would be happy to help you source a microphone along with whatever additional components you need for this project. One of our sales engineers can walk through the setup with you and make sure you get all the right equipment. Please reach out at 888-256-4112 or email sales@proacoustics.com.
We hope to hear from you soon!
Hi!
I have a PVI 6500 Powered Mixer. ( that info came from the silver tag on the back).
I need to purchase minimally 3 cordless microphones. Would you please tell me what microphone brands are compatible? Thanks
Hi Vanessa, Most any brand will interface with that unit. We suggest getting a multi-channel capable (frequency-agile) microphone to allow stacking up that many mics for simultaneous use.
Good day, great info, but can you help me out here? I'm on a budget and thinking of getting a mixer amplifier for my church. Currently have one Keyboard a bass guitar and a drumset. what do you recommend for me?
There are many excellent solutions on the market. Depending on your needs, you might consider the Yamaha EMX series, Mackie PMP series, or Yorkville M-Series. We recommend using Google to find a source locally for sales and warranty support. Best of luck!
It is more a question...can we have separate mixer and amplifier connection instead of a combo type
Yes, you can definitely have a separate mixer and amplifier in your audio system instead of using a mixer/amplifier combo. In fact, many professional audio setups prefer separate components for greater flexibility and control.
sir if i buy a Mixer profx16v3 do i have to buy a amp to make work
Hi Harold, Yes, you will need an amplifier to power your mixer.
What kind of amplifier do I need to drive 8 ceiling speakers? Usage for living area, kitchen, dining room, backyard.
Assuming your speakers are 8 ohm, you can use surround sound A/V receivers for this application. Please reach out if you'd like assistance choosing the best receiver for your needs. You can call (888) 256-4112 or email sales@proacoustics.com.
Hello I just bought 3 powerless speakers, could you provide a recommendation on a product that can take an output from my computer to run on these 3 speakers?
the speakers are red/white not single cable
2 jbl xti 20s and 1 jbl xti 10 center
Hi Isaiah, I would recommend contacting one of our sales engineers to discuss this further. They will be happy to review your application in more detail and provide a product recommendation. You can email sales@proacoustics.com or call (888) 256-4112.
We look forward to hearing from you!
How much watt the mixer amplifier pushes if you connect a speaker to it?
The watts that a mixer amplifier pushes to a speaker will depend on the watts that the speaker is set at. Many 70-volt commercial speakers allow you to adjust the amount of watts the speaker will pull using tap settings.
Check out this video where we explain how to choose your amplifier and properly set your speaker tap setting: th-cam.com/video/-omIOiKUrdw/w-d-xo.htmlsi=k9JHajGZ9b8qQKfD&t=86
I have not been able to get an answer to a question I have about Mixer-amps, so hopefully someone here can enlighten me. Can an active sub-woofer be connected to a line out or aux out on a mixer amp that does not have a dedicated output for a sub-woofer/LFE?
Hey Djard, great question! Yes, you can connect an active subwoofer to a line out or aux out on a mixer amplifier that does not have a dedicated output for a subwoofer/LFE. I hope this helps!
@@ProAcoustics Thanks. I found that "Tape" out also works well.
I have double 15" passive loud speakers
Weighs 6.8 ohms=800 watts
Sensitivity 87db
Frequency Response 60Hz 20 KHz
Which amplifier should I buy ?
Thanks for your question! The Pure Resonance Audio LA21000 amplifier might be a viable option for you. For further assistance or to discuss your specific needs, feel free to contact us at sales@proacoustics.com or (888) 256-4112. We also recommend that you reach out to the manufacturer of your speakers for their recommended amplification.
what's effect if I use mixer without amplifier
Hi there! You can check out this blog for more information on the subject: www.proacousticsusa.com/blog/post/what-is-the-difference-between-a-mixer-audio-power-amplifier-and-commercial-mixer-amplifier/
If the speaker is passive little to no sound will come out
The fact that I don't have enough money I can only buy a mixer amplifier to satisfy me and please what is the use of a cross over?
