I am using my pc audio output for my whole house system. It is fed into 2 Russound PR-4Z pre-amps which feed 2 Niles SI-1230 12-channel amps. I am using a Roland external soundcard connected by USB 2.0. This soundcard choice is mainly for the purpose of connecting my guitars/mikes to my computer. I had an internal Turtle Beach Santa Cruz card, and it sounded just fine through the system. I'm not using any remote yet, but am looking for a way to use my pronto remote to pick songs using a numerical keypad, like you would for a multidisk cd changer. I am currently trying Jukebox Simulator software, and am thinking of getting an iMon remote. The Jukebox simulator will allow you to select the desired song by album/track number (like a jukebox). I like the looks of the iMon remote, and will teach it's commands to the Pronto so I can write macros to select songs.
