From: To: "Je vacation" <jeevacation®gmail.com> Subject: Re: Date: Sat, 28 Aug 2010 12:14:57 +0000 Importance: Normal Jeffrey, In the library system I used an adapter that plugged into the Tuner input on back of pre amp, Take that RCA adapter to 1/8" pin adapter and plug it into the MAC lap top headphone jack, then plug into an "open audio IN" on back of pre amp. That should work... Or: At the mac store or a Radio Shack, you need to convert the 1/8" stereo head phone jack in the back of the lap top to stereo RCA jacks (red & white), then plug RCA jacks into back of pre amp, audio IN, and plug the 1/8" pin into headphone jack of lap-top.
