What effect will the DC offset have on the speakers/sound?
I don't think the offset of the cone would be great enough to even measure with the 25mv. And, with the 6mv definitely you would need a micrometer to measure it! In my design experience - a few years ago, I must say - we did not worry abou... Read More »

Just add. RMS is heating equivalent and you can add them. So add the DC voltage to the RMS voltage of the sine wave. V = Vdc + 0.35*Vpp RMS value of a sine wave is 0.707 x Vpeak or 0.35 x Vpp .

I would like to clarify why I asked you to take more pictures. I've found in my files some notes I took many years ago, when I worked on a similar unit. At that time, I've made a very partial schematic (not publishable) and from the schemat...

Thinking out loud: Visible on the zoomed in pics, it starts with a click, then the whole wave is quickly shifted and slowly returns to zero. If this was a wave, it would be at 1/2 Hz. And we see amplitude one way only (also true for the oth...

it is difficult for u to simulate dc offset of the mixer in schematic design as all circuits and devices are matched. you could set mismatch on some devices, for example, the load resistors(the easiest case) and then simu the dc offset. dc ...

getting pops and clicks on starting and stopping but not recording sounds like DC offset to me. I've noticed that some high feedback settings of certain reverbs can cause it. (Freeverb for example; luckily you can specify some high pass fil...

I don't think an end user or consumer needs to be worried about that. An offset is measured in mv at a point between the output transistors, so this point can be before any final filtering circuit which to output terminals are connected to....
