How much power do I need from my amplifier?

But if you are weighing up amp A, rated at 115 watts per channel, and amp B, rated at 130 watts per channel, just forget about the power output difference. It amounts to an inaudible half a decibel. Instead, consider all the other important things in buying an amp.

Watt Calculator

One of them - Watt''s law - states that: Power = Voltage * Current - in symbols: P = V * I. This power equation, as well as the power unit, were named after James Watt - a Scottish engineer. One watt is the power at which the work performed in one second is equal to one joule: 1W = 1J / 1s

How much power do you need to fill a venue with sound?

Let''s say that you have 1000 watts of power available. This will be supplied to loudspeakers that have a certain efficiency rating. If a loudspeaker can convert 1000 watts of electrical power to 20 watts of sound power, it is doing pretty well at 2% efficiency. The rest of the energy is wasted as heat. So now we have 20 watts of sound …
