Discussion in 'AV Receivers & Amplifiers' started by gipo, Dec 22, 2003.
Im getting a receiver which has (110w DIN) output and 65w rms output.Whats the difference?
they are different measurements of power (watts)
They are different ways of measuring the output power and providing a means of comparing them (to other equipment measured in the same way).
(DIN = Deutsches Institut fuer Normung / German Institute for Standarization
RMS = Root Means Square, a mathematical function)
I would say the RMS value is more usefull - given it's quoted at 8 Ohm, over a frequency range of 20Hz-20kHz and with a reasonable THD.
Sometimes output power is quoted at a different impedance (e.g. 4 Ohm), a fixed frequency or at a THD of e.g. 10% - which is missleading at best (can't put the 'right' word since swearing isn't allowed ) ...
