Amplifier
CLASS A100D3 is the third
amplifier.
The amplifier is designed to provide maximum
sound quality. All inputs and speaker connections
are gold plated and of the highest quality.
A powerful ring-coil transformer contributes to an
effective power supply. Four power output
transistors per channel makes it possible to handle
high currents. The switching between
inputs/sources is done by gold plated relays, which
gives a low distortion and a short signal way
through the amplifier.
The third generation is now built by modules (for
future development) and has got a lot of new
components with improved quality.
The amplifier can be switched between class A and
AB. This means you do not always have to use class
A mode if not feasible. There is also an
available; if the heat sink temperature exceed
the amplifier selects class AB automatically. Class A
or AB mode can also be selected with the remote
control.
CLASS A MODE
Class A mode increases the
the output transistors to achieve the best possible
even when idling, creating lots of heat dissipation
making it very hot.
CLASS AB MODE
Class AB is the standard operating mode among
conventional amplifiers. The maximum output
power is radically higher than in Class A mode.
de is suitable when you want to play loud
for long periods. The risk of overheating is
considerably lower than with class A operation.
Class A mode uses a higher nominal
quiescent current through the output
stage, which in turn produces more heat
dissipation. The output transistors heat
the cooling sink, and the temperature is
measured by a sensor, feeding the
information back to the output stage, thus
regulating the bias.
Cabinet
The new cabinet, with softer corners, is almost
m solid aluminium, enhancing
the quality impression as well as the mechanical
Outer interference is effectively shielded, and the
um contributes to spreading the heat
generated inside. This improves the
dissipation, cooling for the amplifier better.
I high precision volume control maintains a perfect
balance between the channels, regardless of what
volume knob, input selector and remote
control unit are all made from aluminium.
Class A100 D3 has a newly
control, to adapt it to newer functions and make
then handling easier and better.
Preamplifier for MM/MC pick-
to change between MM and MC.
MM = moving magnet ~2-5mV
MC = Moving coil ~0.5mV
