Manipulating line level signals I need to manage several line level signals (physically, not in software), and need to know what to expect. I was expecting AC signals, but am not quite sure. Are line level audio signals AC or DC? What Vpp can I expect?
Audio signals on line level outputs are AC signals with no DC bias, so they run positive and negative around the 0V level. Many devices support 2VRMS output for full scale signal, so that is about 5.66 Vpp.
