A superb digital preamplifier designed to complement the K4000 Valve Amplifier and the K4020, K4005, K4010 and K4004 high powered MOSFET amplifiers, but equally suited to any high quality amplifier. Digital control eliminates the need for conventional potentiometers, all functions being selected and operated by front panel mounted push-buttons. The K4101 I/R transmitter, which is available separately, is used to remotely control the functions. The preamplifier offers a phono input which is suitable for moving magnet or high output moving coil cartridges. Other inputs include CD and tuner, plus two tape monitor loops and a graphic equaliser loop. A switched mains output allows the rest of the installation to be switched on and off, and the power-up default setting can be programmed to individual requirements.
