Dave and Mike,

thanks for your help.

Dave: yes, I plugged the TY in the phono input (the 2 red/white small jacks) on the ampli. I tried with a mixer and it now works fine. BTW, I was just wondering if I could do without the mixer, and simply plug 2 cables from TY's MAIN L&R to the ampli (AUX or else).
Pardon my English, but what does it mean "follow instructions to a T"?

Mike: My pC runs on Win98. It cannot identify the TY automatically, but after 2 weeks I cannot still use the file manager without having the driver installed. I will look for some IT assistance on the PC, and take it from there.

Ciao

Amelio
