I'd like to monitor the amount of power (in watts) going into my speakers. I'm not concerned about over driving them or anything, I'm just curious how much power I'm actually using. I connected a volt ...

A simple stereo audio amplifier is built around two 7905 negative-voltage regulators (IC1 and IC2) and a few discrete components. The circuit will also work with other 79XX regulators if appropriate ...

This simple mosfet power audio amplifier circuit, with TL071C and 2 MOSFETs (IRF9530 and IRF530) can deliver up to 45W on 8Ω speaker or 70W on 4Ω speaker. This schematic is based on Siliconix ...

Stereo reproduction in the fifties morphed from separates built by small high-end manufacturers like Saul Marantz to entrepreneurs like Sidney Harman who is credited with marketing the first receiver.

In the consumer electronics world, knowing the difference between root mean square (RMS) and peak power ratings can make or break the performance and clarity of an audio system. In short, RMS power is ...
