@ 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.

General
On each pair of input or output jacks, the lower jack (marked R)
corresponds to the right channel, and the upper jack (marked L)
to the left channel. When jacks on other equipment or connection
cables are color-coded, the color red usually corresponds to the
right channel (Red = Right).
Turntable Connections
Be sure to connect the ground (earth) lead wire from the turntable
to the ground terminal (GND). Lack of proper ground connection
will cause hum. Also observe the following precautions.
®@ Place the turntable on a firm shelf or desk free from vibrations
(especially those generated by the speaker systems). If the
turntable is permitted to pick up such vibrations, not only will
this unit's performance suffer, but distortion in the bass range
and howling noise in the speakers may also occur.
@ Check the turntable instruction manual for any other precautions.
@ The loud noises that occur when connecting and disconnecting
the turntable leads could damage the speakers. Always turn the
power switch off before making connections.
Tuner Connections
Connect an FM/AM tuner to the tuner input jacks. Be sure the left
and right channels are connected properly.
Compact Disc Player Connections
Connect a compact disc player to the CD-1 or CD-2 input jacks.
Be sure the left and right channels are connected properly.

About the Variable Tone Boosting System
This unit is designed to gradually reduce the effect of the tone
controls (bass and treble) when the volume exceeds a certain
level. The variable boosting system gradually reduces the
boosting effect of the bass [9] and treble controls when
one or both of these controls is turned beyond (to the right of)
the center defeat position and the volume control [5] is turned
beyond the center position. When the volume is turned all the
way up, the frequency response will be flat again. Volume set-
tings below the center position have no effect on the tone
controls. Also, bass and treble control settings below (to the
left of) the center defeat position are not altered by the volume
