Re: Repeater levels/ noise

Well, the repeater amp is pretty hot. I,too can't use the headphones levels
higher than 3. This depends also on the resistance of the headphones. For
example AKG makes two kinds of every serie of headphones, M and S. All the 
have a value of 600 Ohms (and therefore are lower in perceived volume) and
the S are 55 Ohm, so they sound louder.


P.S. Happy birthday LD
