Amplifiers are an essential part of audio production. Without amplifiers, we can’t do any more with the amplification of sound. However, there is a lot of confusion when we want to buy one for our needs. From RMS wattage to impedance and mono to stereo there are several things we need to take care of before choosing a power amplifier.
Actually, different amplifiers are built for different types of works. There is a whole range of amplifiers available in the market according to the specific use. Though, we can divide them in two main categories.
- Studio amplifiers
- Power amplifiers for live sound
The main difference between the two is WATTAGE.
Studio amplifiers are generally low powered ranged from 200 watts to 1000 watts where live sound amps range between 1000 watts to 12000 watts. We need much more loud sounds in live concerts so these amps are called POWER AMPS.
But again, we have a lot of confusion when choosing a power amp for live concerts. From RMS/peak wattage to sound quality, resistance, and brand, there is a huge amount of in-depth knowledge we need to gain, otherwise, we could end up with the wrong choice.
So, I have compiled this list of 9 Best Power Amplifiers for Live Sound that will help you in your search for the best one.
Now without taking any more time, let’s jump into the list.
