One

major

reason

for

the

T-488F’s

excellent

sensitivity

and

tuning

precision

is

the

MOS-FET

varactor

used

in

the

front

end,

This

unwillingness

to

compromise

on

quality

gives

the

T-488F

the

sharp,

precise

reception

you

expect

from

an

Onkyo

tuner.

Onkyo’s

exclusive

APR

system

lets

every

FM

sound

its

It

constantly

monitors

the

and

selects

the

optimum

settings

for

four

IF

can

Onkyo’s

feature

allows

you

to

to

any

DYNAS

The

DYNAS

system

has

been

designed

specially

for

areas

with

many

FM

stations.

In

a

narrow

band

suchas

this

the

signal

of

an

adjacent

station

may

interfere

with

a

tuned

station

and

produce

undesirable

background

noise.

The

DYNAS

system

significantly

enhances

the

tuner’s

selectivity

and

sensitivity

compared

to

standard

FM

receivers,

thus

reducing

of

the

speakers.

Avoid

unstable

locations

and

high

places

from

which

of

similar

surface

that

could

block

the

ventilation

openings

or

placed

in

a

built-in

instatla-

tion,

such

as

a

bookcase

or

cabinet,

that

could

impede

the

flow

of

air

through

the

ventilation

openings.

Heat

_

The

unit

should

be

situated

away

from

heat

sources

such

as

radiators,

heat

registers,

or

other

appliances

(including

amplifiers)

that

produce

heat.

Cleaning

of

the

internal

parts

should

be

performed

only

by

qualified

service

personnel.
