Amplifier
CLASS A100D3 is the third
amplifier.
The amplifier is designed t pr vide maximum
s und quality. All inputs and speaker c nnecti ns
are g ld plated and f the highest quality.
A p werful ring-c il transf rmer c ntributes t an
effective p wer supply. F ur p wer utput
transist rs per channel makes it p ssible t handle
high currents. The switching between
inputs/s urces is d ne by g ld plated relays, which
gives a l w dist rti n and a sh rt signal way
thr ugh the amplifier.
The third generati n is n w built by m dules (f r
future devel pment) and has g t a l t f new
c mp nents with impr ved quality.
The amplifier can be switched between class A and
AB. This means y u d n t always have t use class
A m de if n t feasible. There is als an
available; if the heat sink temperature exceed
the amplifier selects class AB aut matically. Class A
r AB m de can als be selected with the rem te
c ntr l.
CLASS A MODE
Class A m de increases the
the utput transist rs t achieve the best p ssible
even when idling, creating l ts f heat dissipati n
making it very h t.
CLASS AB MODE
Class AB is the standard perating m de am ng
c nventi nal amplifiers. The maximum utput
p wer is radically higher than in Class A m de.
de is suitable when y u want t play l ud
f r l ng peri ds. The risk f verheating is
c nsiderably l wer than with class A perati n.
Class A m de uses a higher n minal
quiescent current thr ugh the utput
stage, which in turn pr duces m re heat
dissipati n. The utput transist rs heat
the c ling sink, and the temperature is
measured by a sens r, feeding the
inf rmati n back t the utput stage, thus
regulating the bias.
Cabinet
The new cabinet, with s fter c rners, is alm st
m s lid aluminium, enhancing
the quality impressi n as well as the mechanical
Outer interference is effectively shielded, and the
um c ntributes t spreading the heat
generated inside. This impr ves the
dissipati n, c ling f r the amplifier better.
I high precisi n v lume c ntr l maintains a perfect
balance between the channels, regardless f what
v lume kn b, input select r and rem te
c ntr l unit are all made fr m aluminium.
Class A100 D3 has a newly
c ntr l, t adapt it t newer functi ns and make
then handling easier and better.
Preamplifier f r MM/MC pick-
t change between MM and MC.
MM = m ving magnet ~2-5mV
MC = M ving c il ~0.5mV
