? An amplifier or an amp is commonly referred as a device that transforms, generally enhances, the amplitude of a signal. The signal is generally voltage or current. While on the other hand a power amplifier is a relative term with respect to the amount of power delivered to the load and/or sourced by the supply circuit. Usually they are designated as a last one in a transmission chain that specifically needs most attention to power efficiency. You need to consider few of the factors while selecting a power amplifier. Choose the amplifier that can deliver power almost twice that of speakers' IEC power. For instance, if a speaker possess load of 8 Ohm and power rating of 350 W then the amplifier should be of 700 W for the similar load. A high quality loud posses the ability to deal transient peaks which is surplus of its power rated. Check whether the one you have can bear the same peaks without any irregularity. By using an amplifier with slightly additional head will ensure that only undistorted power is accessible to the speakers. It is advisable to enquire and consult the customer sales representative before buying an amplifier and speaker. You can also read owners manual for detailed information. Be realistic and decide a budget for yourself. The more the power, the greater the cost, affordability largely depends upon your purchasing power. Do some research and browse through various online stores. Compare the features and prices and buy an AC power amplifier that best fits your requirement. Do remember that a wrong selection can damage the whole system!
