Factory default settings
The KOLEKTOR Preamplifier provides a Reset to Factory Defaults
option which allows you to reset the unit back to its factory
settings. This restores the user options to their initial values, and
resets the inputs to their initial source names.
To reset the KOLEKTOR
VOL+ SWITCH ON
POWER
""""
init
Switch off the KOLEKTOR, using the power switch on the front
panel.
Press and hold down VOL+ (front panel) and switch on the power
again.
Keep VOL+ held down until the display shows init.
The KOLEKTOR Preamplifier will then return to normal operation
with the default settings, as shown underlined in the previous
table.

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.
