In larger venues I have used my 2 JBL Eon 10 G2's as monitors and my 15's as the house speakers. Based on the Pro's recommendation (thanks!) I recently tried the KeyPro KP-200s amplifier and ended up purchasing one from Dano to replace the Eon 10's. The KeyPro is functioning as both my monitor and the house speakers in smaller venues. I set the KeyPro in front of me (not behind as Motion Sound suggests) because I don't want that much volume behind me. I place it on the floor to decrease the treble (since my ears are sensitive to higher frequencies) and also to avoid carrying a 2 foot stand to put the amp on. I find that the sterio image effect is present behind the speaker also.

By using the KP-200S I can avoid carrying a mixer and the Behringer Ultramizer Pro I had been using for sterio enhancement. I replaced a BBE 264R single channel sonic maximizer with the Ultramizer because (to my ears) the BBE added to much high frequency to achieve the sterio enhancement. To my ears the KP-200S creates a wider sterio image than the Ultamizer Pro and adds less high frequency. On the KP-200S, the high EQ can be reduced to compensate for what ever high frequency is added without taking the sparkle out of the sound.

My sound module is an X4 (the keyboard is an accordion). One of the reasons I started using a mixer was because I felt the X4 sounded better through a mixer (compared to going directly into the Polytone "Accordion" amps I was using at the time.) I find the X4 sounds great going directly into the KP-200S.

I use a VoicePrism also and a problem I had using a mixer and the JBL's was hearing the accompaniment when I was singing (since I was hearing my voice directly and also through the speakers). I don't have this problem with the KP-200S - perhaps because it is closer to me than I placed the JBL speakers. When I used the JBL 10's as monitors I had still had the problem unless I had the monitors fed from the Aux out and mixed the accompaniment louder than the mix for the house speakers.

Didn't mean for this to get so long - do talk to Dano about trying a KP-200S before you make a final decision. Or, talk to him about a KP-100S for that matter.

Barbetta amps have been mentioned in some posts. I talked to an acquintance who plays keyboard professionaly in a combo and also rebuilds Hammond organs and he uses a KeyPro KP-200S on the job. He had been using a Barbetta amp (don't know which model) and says there is no comparison. Course, we all have different ears.

Good luck!
