Now you guys are talking about something i can associate with. That first job with the Compact was definitely of poor quality because I compromised the volumes, and I mentioned that. TODAY, I played outside under a huge gazebo, maybe 40x40 with an uncovered patio area twice that and grass covering twice that or more. I could be heard all over the outside area very clearly. Most of the people sat inside the gazebo and i had the volume up to 12 o'clock; it was strong and clear and not one person complained or covered an ear or anything. I would say the Compact can handle 150 people easily.

As for chaining two Compacts together, they're not designed for that at all. you would probably need a small stereo mixer to route the signals properly - maybe a splitter might work, I don't know. If you're running a mic thru your keyboard and cabling the keyboard in stereo you could run R/L to the respective Compacts.
