Note: This has been superseded by the Roland KC-200.

This is a 4 channel amp with volume control on each channel and a master 2-band EQ.

It has an XLR input for dynamic microphones and a stereo RCA Auxiliary input.

Like all the Roland KC series amps it has an output for a subwoofer if you want to beef up the bottom end.

It is used by keyboardists as a practice and performance amp and also as a stage monitor.

It is also used by musicians of all types as an amp and a personal PA system – including acoustic guitarists and electronic drummers.

The vast majority of owners are happy with this amp and the added flexibility of being able to add a subwoofer.
