A power amplifier is an important part of any sound system, regardless of the type of music. An amplifier ensures that every note can be clearly heard through the monitors and speakers. While almost any amp can increase sound output, not every model is designed to work with all systems. To help you find the best amplifier for the speakers used with your sound system we have included the following informative tips below.
When you are searching for the best audio amplifier one of the first aspects to consider is the type, and you need it to be compatible with your speakers.Powered or active models have the speakers and amp in one convenient unit. This makes it easier to transport since there is only one piece of gear to load and carry, and this single unit can also make one of the best home stereo amplifiers due to its compact size. If you aren’t planning on continuing to “build” your system or aren’t worried about having to replace both components if one breaks, a powered amplifier might be the right choice for you.
Passive amplifiers are often found in professional PA systems, and these stand alone models also provide you with more versatility. You can easily replace only one component at a time, and passive amplifiers also come at a more affordable price. If you are planning on upgrading your existing system one piece of equipment at a time you probably want to start with a passive amplifier.
Modes and channels
Amplifiers can come with different modes and channels and it is an important aspect to consider. There are three basic modes for power amps and each one will create a different configuration. In stereo mode you can connect two of the outputs on your mixer to the amp, which is then plugged into the speakers. If you want the speakers to produce the same sounds you want the power amplifier to be in parallel mode. Most amps also come with a setting for bridge mode, but it is important that you read the owner’s manual carefully to make sure it won’t damage your gear.
Almost all power amplifiers have two channels so you can connect the speakers, and some models come with as many as eight. When you are trying to decide how many channels you need it is important to consider where and how you are going to be using the amplifier, along with your budget. If you need to connect more than two speakers for a more professional sound system, it might be worth the added expensive and convenience to purchase one power amplifier with multiple channels.
You want the amplifier impedance to match your speakers if you want to prevent expensive damage to your gear, and this is measured in ohms. If the speaker’s impedance is higher than the amp’s you won’t be able to produce every sound, and if it is too low there is a good chance that it will ruin your expensive gear. Most speakers have ohm ratings of 4, 8 or 16 so you can easily find a power amplifier that matches the impedance perfectly.
How the amp and speakers are connected will also determine impedance, and there are two types to choose from. Parallel connections are simple to figure out, since each speaker connects to the amp separately. It is also the safest way to connect your gear, and is recommended if the impedance varies even a little between the amp and speakers. If have multiple speakers, you might want to choose an amp with series style connections. While it is a little more complicated you can use one connection for several speakers, instead of purchasing two power amps.
Some features to consider include the type and number of inputs and outputs so you can easily connect all of your gear, without having to purchase a second amplifier. Built in digital streaming processing lets you make changes to the signal so you can create dynamic sounds. You also want the power amp to have plenty of “headroom” which prevents the sound from becoming distorted when it passes through the speakers.
