WARNING

Precautions

Welcome!

To prevent fire or shock
hazard, do not expose
the unit to rain or
moisture.

To avoid electrical shock,
do not open the cabinet.
Refer servicing to
qualified personnel only.

- For ST-JX661 ­IMPORTANT: Never connect two mains

leads into a single mains plug.

If the power switch is kept depressed,
you can turn on and off the components
by only pressing the SYSTEM POWER
switch on TA-AV561 or TA-AV661.

On safety

• Should any liquid or solid object fall
into the unit, unplug the unit and
have the unit checked by qualified
personnel before operating it any
further.

On power sources

• Before operating the unit, be sure that
the operating voltage of your unit is
identical with that of your local
power supply.

• Unplug the unit from the wall outlet
if it is not to be used for an extended
period of time. To disconnect the
cord, pull it out by grasping the plug.
Never pull the cord itself.

• The unit is not disconnected from the
AC power source (mains) as long as it
is connected to the wall outlet, even if
the unit itself has been turned off.

• AC power cord must be changed only
at the qualified service shop.

On placement

• Place the unit in a location with
adequate ventilation to prevent heat
buildup and prolong the life of its
components.

• Do not place the unit near heat
sources, or in a place subject to direct
sunlight, excessive dust or
mechanical shock.

• Do not place anything on top of the
cabinet which might block the
ventilation holes and cause
malfunctions.

Thank you for purchasing the Sony FM
Stereo FM/AM Tuner. Before operating
the unit, please read this manual
thoroughly and retain it for future
reference.

Getting Started

Unpacking

Check that you received the following items with the
tuner:

• Audio cord (1)

• AM loop aerial (1)

• FM wire aerial (1)

Hooking up the System

Before you get started

• Turn off the power to all components before making
any connections.

• Do not connect the mains lead until all of the
connections are completed.

• Be sure to make connections firmly to avoid hum
and noise.

• When connecting an audio cord, be sure to match the
color-coded pins to the appropriate jacks: White (left)
to White; and Red (right) to Red.

2 Unwrap 3 lengths of the braided lead wire from

around the frame of the aerial. Be careful to
unwrap only the braided section of the lead wire.
Do not unwrap more than 3 lengths of the lead
wire. Also, be careful not to unbraid the lead wire.

3 Assemble the supplied aerial as shown below.

4 Connect the AM loop aerial to the AM terminals

on the back of this unit.

AM aerial hookups

This section describes how to connect the supplied AM
loop aerial. For the specific location of the AM
ANTENNA terminals, see the illustration below.

AM ANTENNA

What will I need?

• AM loop aerial (supplied) (1)

1 Before assembling the supplied aerial, pull the

lead wire out from the slot in the aerial frame.

ANTENNA

AM

y

AM loop aerial

5 Adjust the aerial direction for the best reception.

The AM loop aerial has a directivity which detects
the signal from some angles more strongly than
others. Set the aerial to the orientation which
provides the best receiving condition.
If a high pitched noise (beat noise) occurs when
recording AM broadcasts, adjust the position of
the AM loop aerial so that the noise disappears.
If you live in a building constructed of reinforced
concrete, or with a steel frame, you may not be
able to achieve good reception since the radio
waves become weaker indoors. In this case, we
recommend connecting an optional aerial such as
the Sony AN-1.

For stations that are difficult to receive

Try repositioning the loop aerial while tuning. Placing
the supplied AM loop aerial near a window will help
improve reception quality.

Précautions

Sécurité

• Si un solide ou un liquide tombait
dans le coffret, débranchez le tuner et
faites le vérifier par un technicien
qualifié avant de le remettre en
service.

Sources d’alimentation

• Avant de mettre en service le tuner,
vérifiez que la tension de
fonctionnement correspond à celle du
courant secteur local.

• Si vous ne comptez pas utiliser
l’appareil pendant un certain temps,
débranchez-le de la prise murale.
Pour débrancher le cordon, tirez sur
la fiche et jamais sur le cordon
proprement dit.

• L’amplificateur n’est pas déconnecté
de la source d’alimentation secteur
(courant continu) tant qu’il est
branché sur la prise murale, même s’il
a été mis hors tension.

• Si le cordon d’alimentation secteur
doit être remplacé, adressez-vous à
un technicien qualifié uniquement.

Installation

• Installez le tuner dans un endroit bien
ventilé pour éviter tout risque de
surchauffe interne et prolonger la
durée de vie des composants.

• N’installez pas le tuner près d’une
source de chaleur, dans un endroit en
plein soleil, poussiéreux ou exposé à
des chocs mécaniques.

• Ne posez rien sur le coffret qui puisse
bloquer les orifices de ventilation et
provoquer un mauvais
fonctionnement.

Remballage

• Ne jetez pas le carton et les matériaux
d’emballage car ils peuvent servir
pour le transport du tuner. Si vous
devez expédier le tuner, remballez-le
comme à la sortie d’usine.
