I went into Sam Ash to get a sound system to us outside. I had all ready picked out one. I spoke with David S and he really helped me to understand that what I had picked out would not have given me what I was looking for. David help me with purchasing the Expedition XP1000 which has worked out fantastic for our services outside. We are able to hook up 4 mics and the portable organ. The sound is very good and you do not have to turn the volume all the way up in order to hear or cause it to disturb the neighbors.
