Bernie, the keyboard provides sufficient output to power your Bose L1 Compact without distortion. I rarely turned my PSR-S050 master volume above the 1-O'clock position, and rarely turned the L1 Compact above the 12-O'clock position for venues with 80 to 100 ppl in the room, even those with high ceilings and lots of sound absorbing material on the walls. Unfortunately, I no longer travel to your part of the world, or I would be able to demonstrate this in person for you. Eddie Shoemaker lives in Stuart, which is all the way on the other coast from you, but I'm sure he could help you set everything up as well.

I think you are worrying about a problem that really does not exist.

Good luck,

Gary
