To clarify, Ive already built the equalizer Im just trying to implement the clipping detector. It appears that two output levels are possible, so I assume there must be a setting somewhere. I also have the option to include a clipping/overload detector, though I have already chosen parameters that will not allow the output to go over 2 volts, given a maximum 3V input. Output rating appears to be as follows: Output level (Low) I think you need to have a look at the manual of your DAC: The problem with a clipped source is if you already have clipping, then as you turn the amp up, you may not notice the onset of clipping (as it is already there) and so you get no audible warning that you are exceeding the amps capability.Ī clipped single has more RMS energy than typical music program material, and so an amp’s max RMS output level can be higher than RMS rated which makes it more likely that speaker coils overheat (depending on speaker rating). It is not an indicator of amp clipping of course as it cant know what the output level of the amp is. The peak indicator is not too sensitive and I believe it represents a modern industry standard behavior of such peak/over indicators (also known as ‘true peak’). Roon’s pipeline information and peak indicator are about informing the user about the audio quality of the digital processing pipeline which on many system can be quite opaque. That’s the point, as the clipping indicator is so sensitive, it’s hard to know what’s really going to harm the system. So, even with the clipping light blinking, i should not be worried about damage my amplier/speaker, correct? Just to be sure: the clipping warning isn’t about the possibility to damage the amplifier/speakers, but only to warning about possible problems in the sound quality, right? Therefore, i thought about using roon to boost +3db on the signal. I’ve just bought a Ps Audio DSJ which outputs a low level signal in the RCA connections, considering that it’s connected to a valve amplifier. That is not the case in playback software where a small, fixed amount of headroom suffices to totally remove the problem. Soft clippers make more sense in systems where you can’t anticipate signal levels in advance. Soft-clipping creates distortion that is less offensive to the ear, but it is still undesirable. The clipping indicator is informing you that a sample value was limited, not warning that a dangerous sample got through.Īll clipping introduces distortion. Roon clamps the samples when they exceed the bounds, so there is no concern about damage. Under these coniditions it makes sense to me that a clipped signal into a woofer would be more damaging than a non clipped signal of the same average power.PEQ in Roon's DSP leads to clipping on some bass heavy tracks The woofer is doing no mechanical work and all energy is lost as heat. But this neglets that the woofer essentially stops at these peaks and we have no idea what kind of cooling is taking place. basically, just hook your dmm up to your amps outputs, play a test tone at your maximum volume level, and slowly turn your gains up on the amp while keeping an eye on the dmm. I agree that you could argue the square wave as simply having double the power and that the woofer would remain unruined if it were rated to handle that thermal load. He also fails to remember that these harmonics are riding at the top of a full power wave. As the author notes the harmonics as a source of movement of the woofer, he fails to mention that the sum of the harmonics look just like the waveform, which is the motion the woofer follows. In a subwoofer system it is not these signals are not harmful to the woofer. In fact when the second author from your first post talks about this indirectly when he speaks of harmonics riding the top of what appears to be a square wave. Ya the high frequency harmonics are the primary danger in a clipped signal. Re: Amp wattage greater than speaker rating
