Amp clipping detector12/8/2022 Note: Its not an issue if individual channel strips show evidence of clipping. Output rating appears to be as follows: Output level (Low) This part of the peak level display is called the clipping indicator. #Amp clipping detector manual#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. #Amp clipping detector software#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. Generally no need to get involve with high supply rails.PEQ in Roon's DSP leads to clipping on some bass heavy tracks For that reason, you might prefer the SIM project: I've also done this (different version, again before I'd seen Rod's), and in most applications it's a better bet. Current clipping will be missed, but sounds equally bad. But do bear in mind that this circuit only detects voltage clipping. #Amp clipping detector plus#I didn't bother because my application was driving a full-range loudspeaker, plus most music has the bulk of its energy at LF anyway. You might like to think about adding pulse-stretching to make HF clipping more obvious. The transistor in the opto-coupler only sees 0.6V. The opto-coupler arrangement is quite nice, and of course can be powered from any rail you like (alter the transistor and LED resistors accordingly). details of this circuit about 2/3 down. As shown, mine is working at 12V or so, from a TDA2030 power amp IC. Depending on how close your amp gets to the supply rail, at clipping, you might need to add one or two more diodes in the emitters of the transistors (or use zener diodes). And of course, you'd need to scale some of the resistor values. Or you could lose some of the volts in zener diodes. To make it work with 180V rails, you'd need to find transistors that can take the entire supply voltage (nearly 400V). Rod's is probably slightly better (albeit rather more complex), but my scheme does work pretty well. I came up with a similar thing (before I'd seen Rod's).
