Congratulations

on

joining

the

thousands

of

proud,

satisfied

owners

of

quality

stereo

components

from

Sansui.

-

As

the

world’s

foremost

audio-only

specialist,

Sansui

has

spared

no

effort

in

making

the

TU-505

one

of

the

most

sensitive,

most

versatile

tuners

ever

marketed.

It

is

packed

with

state-of-the-art

circuitry

and

a

multitude

of

sophisti-

cated

features.

The

easy-to-tune

wide

dial

with

linear

FM

scale,

noise-

free

FM

tuning,

FM

antenna

switch

that

attenuates

exceedingly

strong

stations,

and

convenient

tape

recording

outputs

are

just

a

few

examples.

It

is

distinctively

styled

with

a

refined

satin-black

front

panel,

walnut

side

panels

and

a

highly

rational

layout

of

controls

and

switches.

This

manual

and

the

enclosed

reference

sheet

have

been

prepared

to

guide

you

in

operating

and

caring

for

your

TU-505

correctly.

Please

read

them

once

carefully,

then

retain

them

for

future

reference.

SETTING

UP

YOUR

TU-505

Before

you

insert

the

power

cord

into

a

wall

AC

outlet,

be

sure

to

make

the

following

preparations.

FM

Antenna:

Connect

the

T-shaped

feeder

cable

antenna

supplied

to

the

tuner’s

FM

300Q,

terminals.

Adjust

the

tuner

for

FM

reception

and

stretch

the

antenna

to

a

full

‘T’

shape,

then

adjust

its

height

and

direction

until

you

obtain

the

best

reception.

_

AM

Bar

Antenna:

In

areas

where

broadcast

signals

are

sufficiently

strong,

clear

AM

reception

is

obtained

simply

by

pulling

the

built-in

AM

ferrite

bar

antenna

away

from

the

rear

panel.

Amplifier:

Connect

the

OUTPUT

terminals

of

the

tuner

with

the

TUNER

or

AUX

terminals

of

your

amplifier

(integrated

amplifier

or

preamplifier),

using

the

pair

of

plug

cables

supplied.

Be

FM/AM

RECEPTION

1.

Turn

the

Selector

Control

to

FM

AUTO

or

AM,

whichever

you

may

wish

to

hear.

2.

Select

the

desired

FM

or

AM

station

by

turn-

ing

the

Tuning

Control.

The

station

is

correctly

tuned

in

when

the

Signal

Meter

pointer

has

swung

as

far

to

the

right

as

possible.

If

the

FM

station

received

is

broadcasting

in

stereo,

the

FM

Stereo

Indicator

will

illuminate.

HINTS

FOR

BETTER

RECEPTION

@To

receive

a

weak

FM

station

Turn

off

the

FM

Muting

Switch

and

then

tune

in

the

desired

station.

With

the

FM

muting

circuit

at

work,

the

interstation

noise

commonly

heard

during

careful

not

to

confuse

the

left

and

right

channels.

Tape

Deck:

If

you

connect

the

tuner

to

a

tape

deck,

you

can

record

directly

from

the

tuner.

Con-

nect

the

TAPE

REC

terminals

of

the

tuner

with

the

recording

input

terminals

of

your

tape

deck,

also

using

plug

cables.

FM

tuning

is

shut

out

but

weak

stations

may

also

be

cancelled.

@To

suppress

loud

noise

during

AM

or

FM

reception

Set

the

Noise

Suppressor

Switch

to

IN.

If

no

loud

noise

is

heard,

be

sure

to

keep

it

at

OUT.

@

When

receiving

an

excessively

strong

station

If

the

FM

signal

is

too

strong,

the

received

sound

may

be

distorted

and

crack.

In

this

case,

change

the

FM

Local/Distant

Antenna

Switch

over

to

LOC.

Otherwise,

be

sure

to

leave

it

at

DIST.

SIMPLE

MAINTENANCE

HINTS

OUTDOOR

FM/AM

ANTENNAS

In

areas

remote

from

broadcast

stations

or

blocked

by

such

obstacles

as

mountains

and

large

buildings,

the

‘T’

shaped

FM

antenna

supplied

and

the

built-

in

AM

ferrite

bar

antenna

may

sometimes

fail

to

give

you

clear

receptions.

To

improve

the

quality

of

reception

in

such

areas,

try

the

following

meas-

ures.

Outdoor

FM

Antenna:

Install

a

commercially

available

FM

outdoor

antenna

with

at

least

five

to

seven

elements.

While

such

antenna

may

be

con-

nected

to

the

tuner

either

with

300-ohm

balanced

feeder

cable

or

75-ohm

unbalanced

coaxial

cable,

the

use

of

the

latter

is

recommended

because

of

its

better

signal

transmission

capability,

if

your

budget

allows

at

all.

An

impedance

matching

transformer

may

be

sometimes

required

to

connect

such

antenna,

and

this

should

be

found

out

at

the

time

of

purchas-

ing

it.

After

connecting

the

antenna,

adjust

its

height

and

direction

so as

to

obtain

the

best

recep-

tion

while

actually

listening

to

your

favorite

FM

station.

Outdoor

AM

Antenna:

Connect

the

PVC

cord

supplied

to

the

AM-A

antenna

terminal

on

the

tuner’s

rear

panel,

then

extend

it

outside

a

window

or

on

the

roof,

SHOULD

THE

POWER

FUSE

BLOW

If

the

dial

indicator

should

fail

to

glow

and

your

TU-505

remains

dead

when

you

turn

on

the

Power

Switch,

it

is

possible

that

its

power

fuse

has

blown.

If

this

happens,

disconnect

the

power

cord

from

the

AC

outlet

and

examine

the

power

fuse

on

the

unit’s

rear

panel.

If

you

find

it

blown,

replace

it

with

a

new

glass-tubed

fuse

of

the

rated

capacity

(0.5-

ampere

for

100/117

volts,

0.3-ampere

for

220/240

Sy)

ce

7:

volts).

Never

use

a

fuse

of

a

different

capacity

or

a

piece

of

wire,

even

as

a

stopgap

measure,

or

serious

danger

could

result.

REAR-PANEL

AC

OUTLET

|

The

AC

outlet

marked

‘UNSWITCHED”

on

the

rear

panel

can

be

used

like

any

other

outlet

for

AC

house

current.

The

voltage

delivered

at

this

AC

outlet

is

the

same

as

the

power

supply

voltage

used.

This

AC

outlet

has

a

power

capacity

of

150W.

Before

you

connect

any

appliance

to

it,

be

sure

that

it

is

adjusted

for

use

at

the

same

power

supply

volt-

age,

and

that

its

power

consumption

is

not

greater

than

150W.

VOLTAGE

ADJUSTMENT

Your

TU-505

is

adjusted

to

operate

at

the

correct

power

supply

voltage

of

your

area

prior

to

ship-

ment

from

our

factory.

Should

you

move

after

purchasing

the

tuner

or

send

it

to

someone

as

a

gift,

it

may

be

necessary

to

adjust

the

Voltage

Selector.

To

adjust

it:

1.

Remove

the

two

screws

securing

the

name

plate

on

the

unit’s

rear

panel,

then

remove

the

name

plate.

2.

Unplug

the

Voltage

Selector

once,

and

reset

it

so

that

the

arrow

mark

on

it

faces

the

correct

volt-

age

indication.

3.

Change

the

power

fuse

as

well

whenever

the

power

supply

voltage

has

changed.

For

100/117

volt

operation,

use

a

0.5-ampere

glass-tubed

fuse.

For

220/240

volt

operation,

use

a

0.3-ampere

one.
