DIGITALLY CONTROLLED PREAMPLIFIER
|
A pre-amplifier is an indispensable device
for controlling a power amplifier e.g. our
K4040 valve amplifier or
K4020/K4010
MOSFET amplifiers. When developing this pre-amplifier we opted for
DIGITAL control of all functions so that the end product contains
no potentiometers at all ! All functions, such as volume, tone
control, balance and input selection can be operated using push
buttons. A LED display gives a clear indication of all settings.
All functions can be operated with a remote control unit (K4101
available as an option).
