“Hyper Class A”
The Dussun V series is a new kind of large power
hyper class A integrated amplifier. The “Hyper Class
A” is a “Green” Class A solution, whose technically
successful adaptive-bias circuit achieves the extra
large class A power output objective under
conditions of low-power consumption and low heat
producing. The adaptive-bias circuit with an ideal
specification permits the amplifier to maintain
class A mode output even if the speakers’ impedance
drops largely and output power increases several
times. This situation is different from the
traditional pure class A amplifiers’ inevitable
situation of returning to class B when the speaker
load impedance goes down, and is much close to the
ideal class A amplifier essence.
Overview of V6i integrated amplifier
is an extension of Dussun’s high-end product line.
The objective of the development of the V6i, built
on mature Dussun products, is:
improve sound quality
enhance the power output stage driving; and,
control capacity upon speakers.
design features of the V6i include: the output stage
peak current was designed up to 60 A, and the
transformer capacity per channel was designed up to
600 VA. In order to increase sound quality, and to
modify the V6i harmonic spectrum for much lower odd
order harmonic wave energy, V6i employed the
adaptive-bias circuit with an ideal specification.
multi-stage power supply and system loop not only
increased the V6i signal-to-noise-ratio to a higher
level, but also suppressed the AC power source hum
which many times contaminates the purity of the
music under a large power output, as well delivered
extreme high purity and silence of aural feeling
while playing strong dynamic music segments.
inner configuration of the V6i followed Dussun’s
successful full-symmetrical style. This effective
configuration is essential to make the V6i achieve a
large power output and low noise objective.
an independent dedicated protection circuit with
complete functionality for per channel, which can
auto-diagnose probable overload and malfunction,
then auto-protect accordingly.
preamplifier stage and power amplifier stage are
open to the user, allowing the user to use V6i’s
either preamplifier stage or power amplifier stage.
For general use, V6i’s preamplifier stage and power
amplifier stage were linked by a pair of link pins.
If the link pins are removed, it is easy for the
user to use either V6i’s preamplifier stage or power
amplifier stage respectively. The volume control is
built in the preamplifier stage, so the preamplifier
output signal level is controlled by the volume
terminal open for the user, the preamplifier stage
is driven by a high performance low inner resistance
buffer, which can drive many kinds of power
amplifiers with more than 600 Ohm input impedance.
The volume is not controlled by the volume control
knob if the V6i’s power amplifier stage is operated
(infrared) Remote Control can be used to control the
V6i’s volume and input signal selection.
