Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The K3000FX Ultratone is Behringer's solid-state stereo keyboard amplifier with a built-in digital effects processor. It is laid out as a small stereo mixer: four stereo line inputs, each with its own level and effects send, with an XLR mic preamp added on input 1, plus a tape input, stereo link in and out, headphone out and balanced XLR line outs with ground lift. The effects section has its own program display, return level and footswitch jack.
