hello , i was donated a NAD 2200 & NAD 7175 receiver. plus a pair of ADS 100 watt @8 ohms. i'm trying to use the 7175 as the preamp ( for eq's) & the 2200 for the amp .... i know i have to use the Preout from the 7175 and connect to the amp. does anybody know the proper way to connect these speakers. ? i want to hear speakers in stereo. thank you .
