Mcintosh solid state owners, I need a small favor


Hello,
  I have my MC452 for 3 years. I have always used Unbalanced cables to the Amplifier. So, about a month ago I switched to XLR's. But, I never flicked the Balanced/Unbalanced switch on the back of the Amp. I forgot.

 So, here is where I need the Favor. When I switched the switch, while music was playing, I noticed a big drop in volume. I put the switch back to unbalanced and it got louder. So, I have XLR's connected and threw the switch and the music got lower? Put it back to Unbalanced and it got louder?

 Maybe someone with XLR's connected can try this? And let me know if you get the same result?

 Maybe someone else can explain why?   

 Thank You

it is a 3 db drop going to unbalanced from balanced, if the circuit is a true balanced one - one leg of the 3 pin circuit is dropped off, so half the voltage is sensed on the receiving end ... not sure if your mac is true balanced though
Cut and paste straight out of the owners manual to that post...
