Jim (the Pro): Do you feed both vocals as well as the keyboard mix thru your KP-200? If so, what 'stereo expander' setting do you find the best for this situation? I assume it's also possible to turn OFF (bypass) the stereo enchancer feature completely, right?

Scott: Hmmm... let's qualify my answer: I don't sing ! So my mic, which is for announcing only, is hooked up to the mic input of the 9000 Pro and then the sum stereo signal from both the keyboard and mic goes into one channel of the KP-200s. The amp has two stereo channels (each channel has it's own pair of L/R inputs) and Channel #2 controls a lo-z mic input (on the back of the amp) so it can be used as a dedicated vocal channel. Each channel also has it's own stereo enhancer control, which is a knob from 0-10, so you can turn the effect completely off and just have normal stereo - you'll find normal stereo to be a little dull in comparison though.

I don't think the enhancer will have any effect on your main vocal but it probably will affect the sound of your harmonized backing vocals if they are spread in a stereo field (it might make them sound better!). The enhancer doesn't do anything with mono sources, only stereo ones.

BTW: earlier I said that the stereo enhancer reversed the phase of the speakers - to be more precise, it changes the phase of the stereo SIGNAL, not the speakers themselves.

I know what you mean....when I originally test drove this amp at my local music store, I was dumbfounded when I heard it was discontinued. It sounded great, and still does. That 10 inch speaker which is transversed to the right is actually the right channel of the stereo image. I play on the left side of the stage all the time and I can play around with the deflection by pointing the face of the amp at the band and the traversed speaker at the crowd.

You can find these amps on Ebay from time to time, but they sell for quite a premium now. I've been looking for the matching sub-woofer for a while now without luck. There is a separate sub output on the back which would be kind of fun.

I must say, you guys have me curious about the Motion Sound amp. I may have to toddle off to the music store this weekend to check it out (if they have it).
