Though it does, to some extend, depend on the amp and the nature and calibration of the volume control. Regarding clipping, definitely, without a doubt, there is clipping at the 1 o'clock position. So looks like this annoyed too many people and might even answer my own question. The unit will indicate this by flashing the protection LED for several seconds." However, to enable the clipping detection, hold down the Standby/On button during power up (whilst switching on the unit at the rear panel power switch). no speakers connected, does the clipping protection matter at all ?Įdit: I noticed this in the 650A manual: "The clipping detection is disabled by default. I know you can defeat the clipping protection by holding down the standby button when powering on, and I am assuming that the clipping is based on the input signal, not the output since I have no load on the speakers, but is there any potential for harm if I do this ? i.e. When I tried this through the 640A acting only as a pre-amp (source switch & volume) the clipping protection would kick in when the volume control was about 1 o'clock and annoy me since the DefTechs love to be driven quite a lot I want to resurrect my old Sony CD player and I happen to also have an old 640A V1 lying around so I re-wired it all through that and set the SB3 to 100% output. It appears that two output levels are possible, so I assume there must be a setting somewhere.I am running a pair of DefTech BP10 speakers from a pair of Audiolab 8000M driven directly by a Squeezebox classic using the internal volume control. 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. PEQ in Roon's DSP leads to clipping on some bass heavy tracks
