CD

Direct

Switch

Onkyo's

“direct

in”

design

philosophy,

which

aims

at

keeping

the

signal

path

as

short

and

unencumbered

by

unnecessary

tone

controls

as

possible,

is

fully

in

evidence

in

the

A-8190/A-8170.

All

of

the

input

signals

benefit

from

the

ingenious

circuit

design

which

cuts

the

number

of

switches

in

the

signa!

path

to

an

absolute

minimum.

tn

addition,

the

“CD

Direct”

switch

bypasses

all

of

the

preamp

section's

tone

control

circuitry

and

switches

including

the

common

volume

control

and

input

selector.

The

CD

player's

output

signal

is

routed

through

its

own

fourgang

volume

contro!

separate

from

that

used

by

the

other

components

and

then

straight

into

the

power

amp

section.

Video

input

Capability

The

A-8190/A-8170

comes

with

two

video

inputs

(video

disc

player

and

VCR)

and

one

video

output

for

a

TV

monitor.

The

video

signa!

path

is

entirely

separate

from

the

audio

circuitry

and

is

all

located

as

close

to

the

video

input/output

pin

jacks

as

possible

so

as

not

to

cause

interference

to

keep

the

picture

sharp

and

clear,

no

video

amplifier

is

used.

Signal

In-Phase

Filters

The

purpose

of

these

filters

is

to

prevent

unwanted

sonic

colorations

and

interference,

whether

with

analog

or

digital

sources.

They

work

by

reducing

common

mode

electrical

noise

while

maintaining

phase

fidelity.

This

is

achieved

without

resorting

to

increased

negative

feedback.
