What I have learned about my Bose compact amplifier and my keyboard:
The high tones are great; the lows are very strong; and the mid’s are fair. With a bit of tweaking the mids become acceptable. The instrument channel has a volume control, no tones controls. The second channel is for a microphone, that has volume, bass and treble controls. Over all it is a fine almost distortion free sound.
My problem.
The Kn7000 and Bose Compact are a good match. The clarity is outstanding. The Korg Pa800 has a good sound through it’s own speakers but through the Bose it falls short in clarity, it is not as alive.
My questions: If you have or had a Kn7000 and a Bose amplifier and have added another keyboard to your Bose what are you hearing? Have you lost anything? If you have, what have you done to improve the sound?

Thanks, John C.
