I have just installed a new Pio 501 100watts RMS, to drive my Mission FS6.1 AV system, and have been trying to setup to play stereo CDS . I have noticed that i get no sound out of the speakers until approx -40DB, Is this normal ? If i want to listen at reasonable listening levels, i have to turn it up to -20DB, and even this isn't that loud. I hve run the MCACC setup, and cannot understand why i am having this sort of problem, any thoughts, about how i can listen at about -25DB to -30DB, and adjust my Amp to change it sensitivity into the Missions ? Or am i looking, at a mismatch with these speakers, if so which Receiver would you recommend to drive the Missions ?
