Power and Volume

When it comes to AV receivers, power and volume are two important factors to consider. Power output is measured in watts and it determines how loud your speakers can get. However, more watts do not necessarily mean more volume.

The relationship between power output and speaker volume is logarithmic, not linear. This means that an amplifier with 100 watts per channel does not play twice as loud as an amplifier with 50 watts per channel using the same speakers. The difference in maximum loudness is only slightly louder, and the change is only 3 dB.

Distortion is another important factor to consider when it comes to power output. Distortion occurs when the amplifier is pushed beyond its limits and it can cause a loss in sound quality. The total harmonic distortion (THD) is a measure of how much distortion the amplifier produces. A lower THD is better, as it means the amplifier produces less distortion.

Decibels (dB) are used to measure sound levels. The human ear perceives a difference of 10 dB as being twice as loud. For example, if an amplifier produces 80 dB of sound, an amplifier that produces 90 dB of sound will be perceived as being twice as loud.

when choosing an AV receiver, it is important to consider the power output, distortion, and decibels. More watts do not necessarily mean more volume, and a lower THD is better for sound quality.

Control Options
