We know that to obtain the maximum audio level between two devices we must
match the impedances between them. The impedance of mono and stereo headsets
vary widely a good way to tell is if you have to rotate the volume control a
lot to get a small increase in volume there is a mismatch.The questions are:
What are the headphone output impedances of the front panel and the rear
panel jacks and do they vary between modes?.
