touring sound system - audio source levels

jseter · 06-20-2010, 06:25 PM

hi guys -

searched for a bit and couldn't find much -

any thoughts on why the audio levels vary so greatly between FM / SAT / CD / AUX ?

it's like there is a separate gain on each input and it doesn't feel natural

CD volume at 12 or 13 equals SAT volume at 18 or 19

same with AUX vs FM

weird ?

Iv'e noticed the same issue. sat volume is always higher than cd.can't say for sure why. on aux same thing when i play my iphone music i have to turn it up to 18 or 19 i think that has something to do with the music being compressed.

CD, aux are direct digital input. With any radio transmission, you're losing a lot in the transmission. I'd had to guess and say that you're not getting the full wavelength of sound from the radio transmission.
