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.
