Audio amplifier

Description

An audio amplifier is required if your speakers are not self-powered. Using an amplifier with quality passive speakers will allow for greater volume than self-powered speakers. It is important to make sure that the wattage capacity of your amplifier is compatible with your speakers. For example, if your amplifier can support 100 watts on each channel, use 100-watt speakers. Many amplifiers also include limiters, low frequency filters, and overload protection, though additional equipment can yield greater control. There are many distinctions between consumer "home stereo" and professional amplifiers. Professional equipment is designed for maximum sound fidelity at any volume, and is built to sustain longer hours of use.
