I have an early 70's Olson reciever and on the back it has a switch labeled de. emp

I have no idea what it does.The unit has a mic input,and a knob to turn on the mic and control volume.

Anyone know what it does?

De-Emphasis for the FM tuner section. So it could be used overseas as well (The UK and Europe used a different pre-emphasis for FM, which was also used with the short lived Dolby FM)
