It is unusual to have tone controls in a preamplifier of this performance level. However, the controls in the KOLEKTOR are very different from conventional bass and treble controls, which cause extreme distortion to the audio signal. The bass control in the KOLEKTOR has its maximum effect around 40Hz, and the treble control at 20kHz. These are at the extremes of the audio band and are intended as subtle refinements to the playback system, used to compensate for smaller loudspeakers, a small room, or a lightly furnished acoustically ‘bright’ room. When set to flat they are transparent to the audio signal.
Control module
The control module is compact, versatile, and powerful. This power makes the KOLEKTOR very easy to use and gives you many facilities not possible in a conventional preamplifier. We have been using microprocessors in our preamplifiers from the very first one we built (the LK1). The KOLEKTOR has two microprocessors: one does all the work, and the other looks after the process of loading the software into the main processor.
As we are obsessive about preserving the signal integrity through our products we take extreme care to prevent any noise escaping from the control circuitry. Only two wires carry the communications between the control and audio modules. They have electrical activity only when you are changing an input or the volume level. A small dedicated power supply on the control module ensures that the power demands of the control circuitry have no effect on the main audio power supplies.
