Necessity isn’t always the mother of invention – sometimes convenience is the mother of them all. For the KB Series Peavey packed plenty of both, along with the reliability and power that have become their trademark, into five essential multi-purpose amplifiers. If Peavey only wanted to design the industry’s best keyboard amps, then they could have stopped with incredibly clean, powerful sound. But then they thought about all the cool things you could do with a multi-channel keyboard sound system, like adding a vocal mic, stereo effects, guitar and bass, plus all of your backing tracks, samplers, MP3 players and other gadgetry.
The KB4 was designed as a personal PA system in a keyboard amp. The KB4 features separate inputs on each channel and can easily handle voice, microphones and other instruments, including acoustic and electric guitars, drum machines and backing machines, such as CD and DAT players. Other essential features include stereo effects loop, ground lift, master level, XLR balanced stereo line out, DDT defeat switch and the capability to drive an external speaker.
Basically self-contained, compact sound systems, the KB series amps are perfect for voice, keyboards, acoustic and electric guitar, drum machines and backing machines.
