Jul 26, 2013 · Using the power calculator, the required amplifier power (including headroom) is 11 watts, which is lower than its power output of 75 wrms per channel. Thus, I'm not likely to clip my speakers at this point. b) Let's say I want the music a little louder. I increase the volume to achieve 80 dbSPL.

Few amps have a dynamic headroom of better than 1 or 2dB, and the greater the headroom, usually the cheaper the power supply for the rated power. An amplifier with a much greater music power than its 'RMS' power usually has a transformer and/or filter capacitor that is too small. In most cases, a 90W (RMS) / …

On some devices and/or ROM versions, you need to turn the DVC feature off. This may reduce the maximum available volume slightly.
