Need your help on connecting my PC directly to a power amp I've ordered (Emotiva UPA-2). This amp has 125 Wx2 @8Ohms and has a gain of 32 dB (input sensitivity voltage is not mentioned). I figure this 32 dB means that the amp can boost the input by about 42 times. I don't want to buy a preamp if I can avoid it. Can I directly connect the power amp to audio out of the motherboard. What voltages do motherboards generally output the audio with? I know that soundcards put out about 1-2 V. I'm thinking of buying the Intel DG-45 ID but online documents don't have this figure. Thanks for youe help.
