THD reading in percent?

Perhaps this question has a solution as obvious as most turn out to be. But so far it has eluded me. I would like to see if I can get the THD measurement in the box at the top of the screen to display in % instead of DB. The purpose of this is “for the customer” who knows that .0xx% THD is good, but has no clue what -65dB THD means.

Thanks in advance :slight_smile:


Hi @BBTV .I don’t know if you mean this, but just click on “L: THD%” and “R: THD%” and the screen will display the % THD values.

Claudio, thank you so much. I think that is exactly what I mean. I must have completely missed that screen somehow, but then again I’m just now getting back to learning this device after several months of “doing other stuff”. I’ll check this evening; hopefully i’ts just that simple :slight_smile:

Hi @BBTV . Just to remind you how to get the window with the various options

Yup, got it now lol. I used to be good at this stuff once lol. Next miracle is putting in the -12dB offset that is the output of the QA451 load box :slight_smile: Tomorrow. Today’s for skiing.

Hi. Right-click on the “dBV” button and then in the window that opens enter -12 in “Input Gain (dB).” Happy skiing! :smiley:

Thanks again Claudio. Haven’t left yet. Do you have the entire QA menu structure memorized? LOL. I did actually find it before I got your Email. One has only to look hahaha.
