Roland KC-880 is one powerful amp!

The KC-880 is a very powerful stereo keyboard amp. I fed the signal from a Roland Atelier AT-90S organ through it for a Veteran's Day concert at a large church with very high vaulted ceilings, lots of angles in the sanctuary, hundreds of people in attendance, and the amp was partially obscured behind the pulpit and an 8-foot altar. I ran the organ master volume on 6 and the KC-880 master volume on 4, and had more than enough volume to play thundering Sousa marches and the Armed Forces service songs.

The KC-880 has nice XLR outputs to feed signal to the house PA, a nice feature although I didn't need it for this concert. The dual 12-inch woofers easily handle all the low end I fed it from the organ -- and I fed it a LOT of bass during the marches. 4 channel inputs, FX and tone controls make this amp very versatile for any type of room.

Hi freq hiss began to appear above a master volume setting of 6, though you would not hear it with a signal coming through the amp, and I did not go above 4 for this performance. A hi freq rolloff filter, or a quieter amp, would help with this issue.

All-in-all this amp was everything I expected from a Roland product, rugged construction, gutsy performance, versatility, good sound, and enormous volume. And heavy! 100 pounds of guts!

Sweetwater sound did an outstanding job getting this amp to me in a VERY timely manner -- 2 days! My sales rep Scott facilitated sales order processing and shipment and communicated with me directly via email. It was conforting to know that someone at Sweetwater was going to make sure I got the product on time and was happy with what I got.

I'll be back, Sweetwater! Thanks for outstanding service! You get a 5!
