The 300-Watt K3000FX gives you four stereo channels, each with separate volume and FX SEND controls, plus Channel 1 has an additional XLR mic input for direct connection of a dynamic microphone. So, if you're the kind of keyboardist with multiple instruments at your disposal, the K3000FX is ready to handle up to four independent signals. It is also ideal for use as an all-in-one solution for keys and vocal applications. The onboard 24-bit digital FX processor, with 100 amazing presets, adds a high-tech dash of reverb, chorus, flange, delay, pitch shift and other effects to your sound.
