Hello,
As the title suggested, I don't understand why a sine wave can't be used to test modern, high-power, class d amplifiers.
Some of the large PA amps I've recently looked at have dsp build-in which appear to clamp down any waveform that looks like a continuous sine wave.
Would someone be able to explain the reasoning behind this? Is it the Class D amp or the SMPS that is the issue?
Considering the waveforms of some modern music, does this not affect the audio quality? Some synth music is very sinewave based. How does the DSP differentiate?
So if you can't use a sine wave, how could I perform a frequency sweep of an amplifier? I have one particular amp that has built-in dsp and speaker presets, I'd like to see the crossover point and such.
Thanks in advance for your help.
