How to Choose the Best Amplifiers?
Compatibility of the Amplifier to the Speakers
What you need to consider before buying a power amp is that if it matches the speakers. To find a power amp for your PA speakers, you need to look for an amp that can deliver power that is equivalent to double the speakers’ continuous IEC power rating. For instance, if your speaker has a nominal impedance of 8 ohms, along with 350 W of continuous IEC power ratings, then you will need a power amp that can generate 700 W into an 8-ohm load.
If you are looking for high-end amplifiers, then these are designed with extra headroom. So, what is this extra headroom? It is a term that is commonly used when discussing power amplifiers. Having a little room above the required power to satisfy the RMS requirement of your speakers is a good consideration. This extra power has several benefits. You can turn up the amp without worrying about it causing any distortion to the music. This is especially beneficial when you need to play music louder than usual. Say, you are playing music at a big venue, and catering to more number of people. This extra headroom lets you play music in a wider dynamic range. What we mean is that if your music has low and high notes, they will be more distinct. You won’t experience any stutter, and the music will seem seamless.
But, if you are looking for budget-friendly devices, then you should be cautious of the product you are choosing. If the speakers and amplifier are not compatible with each other, the amp might damage your speakers. So, if you are buying amps, then we suggest you opt for reputed brands, such as Bosch, Yamaha, Logitech, Barry John, Denon and Dynatech.
Speakers produce their own sounds, and what we mean is that the sound coming from a speaker is never truly original. The speakers twist the original sound, creating a vibration, even after the signals have stopped. This is commonly known as ringing or time-smearing. For instance, if the signal is a heavy drum stroke, your speakers vibrate, even after the drum signal stops.
What are Ohms?
Ohms are essentially the measure of resistance. Audio amplifiers are designed with 4, 8 and 16 ohms. If the total resistive load of the speaker is high, the power delivered to the speakers will be reduced. On the other hand, if the resistive load of the speakers is low, the power delivered will be high. This can potentially damage the speakers.
Filters and Crossovers
Some amps come with a high-pass filter, which is also known as low-cut filter. This filter helps reduce the output of a speaker. Now, how is this beneficial? It lets the amp focus its power on higher frequencies, rather than the bass frequencies. This kind of filter also helps eliminate audio distractions, such as bass rumble, microphone thumps and wind noise. If you want the amp to handle the bass, you can consider a separate subwoofer.
Some amplifiers can offer more refined crossovers. Crossovers are filters that divide the incoming signal into multiple frequency ranges. Crossovers are particularly useful for multi-speaker setup for systems that come with a subwoofer. With a crossover network, you can control which frequencies go to which speakers. This maximises the efficiency of the amp’s power by helping the amp judiciously use the power to reproduce certain high and low frequencies.
