Music amps will naturally waste some amount of energy they use up. A number of challenges are attributable to audio amps which have low power efficiency: Low-efficiency amplifiers are going to waste some energy as heat and so are more expensive to run than high-efficiency types due to their higher energy utilization. The amp hence will become fairly big and pricey. Also heat fans are going to produce operating noise. In order to help dissipate heat, low-power-efficiency amps will need enough air movement. Additionally, they can’t be fitted in water-proof enclosures.
Low-efficiency products consume more overall power to output the … Read the rest
