Amplifier Ratings – What Do They Mean?36

When shopping for an amplifier, you'll likely come across a variety of ratings. These ratings can be confusing, but they're important to understand so that you can choose the right amplifier for your needs.

The most common amplifier ratings are:
Power output
Impedance
Headroom
Signal-to-noise ratio
Total harmonic distortion

Let's take a closer look at each of these ratings:

Power output is the most important amplifier rating. It tells you how much power the amplifier can deliver to your speakers. Power output is measured in watts, and the higher the wattage, the louder the amplifier will be.

Impedance is a measure of how much resistance the amplifier sees from the speakers. Impedance is measured in ohms, and the lower the impedance, the more power the amplifier will deliver to the speakers.

Headroom is the amount of power the amplifier can deliver above its rated output. Headroom is important because it allows the amplifier to handle sudden bursts of power, such as when you're playing music with a lot of bass.

Signal-to-noise ratio is a measure of how much noise the amplifier produces. The higher the signal-to-noise ratio, the cleaner the sound will be.

Total harmonic distortion is a measure of how much distortion the amplifier produces. The lower the total harmonic distortion, the more accurate the sound will be.

When choosing an amplifier, it's important to consider all of these ratings. The power output, impedance, and headroom will determine how loud the amplifier will be and how well it will handle different types of music. The signal-to-noise ratio and total harmonic distortion will determine how clean the sound will be.

By understanding these amplifier ratings, you can choose the right amplifier for your needs and enjoy great sound for years to come.

Here are some additional tips for choosing an amplifier:
Match the power output of the amplifier to the impedance of your speakers. If the amplifier's power output is too high for the speakers' impedance, the speakers could be damaged.
Make sure the amplifier has enough headroom for your needs. If the amplifier doesn't have enough headroom, the sound will be distorted when you play music with a lot of bass.
Choose an amplifier with a high signal-to-noise ratio and low total harmonic distortion. This will ensure that the sound is clean and accurate.

By following these tips, you can choose the right amplifier for your needs and enjoy great sound for years to come.
