Bill,
Tonight I played my first gig with my Bose L1. My setup is very simple - one Tyros 3 keyboard run directly into Chans 1 and 2 of the Bose and a Crown mic run through the keyboard. I place the tower right next to my keyboard - not behind me. Tonight I ended up with about 200 people in a packed room and lots of noise. I used preset 55 with my Tyros EQ'd. The really interesting thing about tonight was the sound level of the Bose. I run the remote controls at 12 O'clock with the mid-level control at 11 O'Clock because the mids seem a little hot to me. I run the remote master vol at 9 O'clock and never had to change it tonight.
During the gig I wasn't sure if the folks in the back could hear or not but no one complained so I didn't change anything. I did do a sound check before the gig - but the room was empty so I wasn't sure about the sound level with the room full.
After the gig I asked the people right up front(about 4 feet away) and several people in the back and all of them said the sound was perfect and they could hear very well. The PAS seemed to handle the situation very well and what is even neater is the sound at the keyboard did not have to be overwhelming.
I have found the Bose PAS very simple to use and setup and with the help of a few forum friends very easy to get to sound the way I like it. Looks like a real winner for me.
