[QUOTE="Lasherž, post: 8714566, member: 679555"] What's being referred to is true RMS. Technically it's true that voltage readings can fluctuate as the frequency changes, however the peak is going to be in the 200-500hz range almost certainly for that amp, which most meters are designed to accommodate within their accuracy tolerances. You'll hardly see a difference with most meters until after 1khz, but true RMS won't necessarily spare you from this. Multimeters of any sort are no replacement for an o-scope, and will often deviate above 1khz, TRMS or not. What true RMS actually means is that the sine wave doesn't need to be a perfect sine wave to get an accurate reading. The non-TRMS meters are set to accept sine waves with an RMS value of 0.707, which represents a perfect sine wave. The sine wave on these tones are very close if not dead on to sinusoidal and thus it's not a requirement to have a true RMS reading so long as you aren't feeding it clipped signals from the headset (which you avoid by choosing 3/4 of the volume). Obviously if you have a TRMS meter it's generally better overall, but you shouldn't doubt the accuracy of your meter simply because it's not TRMS in this specific exercise. [/QUOTE]
