3.1 Layout
LayoutLayout
Layout
The power amplifier 710 is realised as symmetrical dual mono circuit. Left and
right audio channel each has identical circuit boards. The o erall layout has been
optimised for shortest signal paths. All high current signal paths ha e solid copper
bars for minimal losses. Critical components ha e been stabilised with massi e
aluminium plates.

3.23.2
3.2 Amplification circuit
Amplification circuitAmplification circuit
Amplification circuit
Immediately following the input connector the music signal is buffered in the power
amplifier 710 and is therefore transmitted with low impedance to the entrance of
the following error amp, an extremely fast operation amplifier whose negati e feed-
back seizes de iations fast and precise thanks to the high process-speed, pro iding
for a corrected howe er still non-amplified incoming signal. Next follows the true
core element of the power amplifier 710: the “fixed gain”- oltage amp. This highly
linear (0.1 dB le el de iation, 0.005% THD+N) amplifier stage can perform its full
precision only under constant thermal conditions; therefore it is combined jointly
with the error amp in a module casted with synthetic resin.
Per channel fourteen bipolar power transistors fixed on a massi e copper rail and
permanently temperature controlled for a constant idle current, pro ide finally for
the gigantic current rating of the power amplifier 710 of more than 60 ampere.

With the gi en linearity of the amplifier-stages it is in our iew finally the stability of
the supply oltages, being the power supply unit, deciding if a properly working am-
plifier is truly well sounding. The power supply unit of the power amplifier 710 is
equipped with two 1’000VA- toroidal transformers, capacitors with a total capacity
of nearly 250’000 microfarad and discrete rectifiers. All in all we use 10 separated
power supply units. The power supply for both the error- amp and the “fixed-gain”-
amp is stabilized in arious stages.
