I looked up your Acoustic amp, it's a full range amp with 4 inputs so all you do is split the stereo signal from your source into L and R and put those into channels 1 and 2 in the amp and hear what it sounds like. If it's acceptable then you're good to go. You haven't told us yet exactly what are you using for sound now? Is it a desktop or laptop computer? Do you have a laptop? Do you have an audio/midi interface or are you just using your computers internal soundcard and what synth are you using for midi now?

If you're using your internal soundcard then run over to a Radio Shack or music store and pick up a 1/8" stereo mini plug to two 1/4" plugs splitter and use that with two 1/4" patch cords to your amp. Play any Biab song just using your midi synth no RT's and hear that but pan the bass and drums full left to one channel and everything else full right to the other channel. Then use some RT's and hear that through the amp. Then try to set this up in a big room or even outside to test what it sounds like in a big space like a VFW hall. If you're playing in the little bar off to the side in most VFW's then your living room may be close enough in sound.
