@ Onkyo Exclusive AEI Transformer (Patent Pending)
Conventional
transformers
suffer
from
relatively
high
levels
of
electromagnetic
flux
leakage,
and
this
can
adversely
affect
the
sound.
Onkyo
has
developed
a
completely
new
type
of
El
transformer
to
remedy
this
defect.
It
uses
a
special
core
configuration
and
silicon
steel
shielding
to
minimize
flux
leakage
from
the
core
and
coil.
The
result
is
an
overall
reduction
in
flux
leakage
of
22
—
27
dB
compared
with
conventional
El
transformers.
(That’s
approximately
1/12
—
1/22
of
previous
levels.)
In
fact,
during
heavy
loads,
the
AE!
transformer
produces
even
less
magnetic
flux
than
a
toroidal
unit.
The
result
is
lower
distortion
levels
for
purer,
more
musical
sound.
@ Low Impedance, Tri-Terminal Regulators
Both
these
amplifiers
employ
only
strictly
selected
parts.
The
voltage
regulators
used
to
suppress
ripple
voltage
are
one
example.
They
stabilize
even
large
fluctuations
in
voltage
and
are
virtually
unaffected
by
extremes
of
temperature
or
load.
Ripple
voltage
is
reduced
approximately.ten
times
more
effectively
than
in
conventional
units.
The
output
impedance
is
only
about
one-tenth
of
the
level
for
previous
designs.
The
highly
stable
regulated
voltage
output
from
these
units
constitutes
an
ideal
power
supply
for
the
equalizer
circuitry.
@ Source Direct Switch
This
useful
feature
lets
you
enjoy
the
purest
sound
possible
from
any
program
source.
