What Behringer say:
The incredible SONIC EXCITER SX3040 will make your live performances and recordings more powerful, dynamic and superbly articulate. Equipped with a special phase-compensating Bass Processor and Sonic Exciter, the SX3040 adds amazing depth, punch and sparkling clarity – to dramatically enhance sound quality. And thanks to SX3040’s twin channels, you process a stereo signal, or a bass in one channel – and a keyboard, vocal or guitar in the other.
