manufacturer.

It is recommended that the unit be operated from a

suitable DC supply or batteries during initial check-out

procedures.

CAUTION: Before returning the unit to the customer, make sure you

make either (1) a leakage current check or (2) a line to

chassis resistance check. If the leakage current exceeds 0.5

milliamp, or if the resistance from chassis to either side of

the power cord is less than 240 k ohms, the unit is defec-

tive.

WARNING — DO NOT return the unit to the customer

until the problem is located and corrected.

\bschiuBimpedanz-Anpassung des CA-5EI/CA-5AI/CA-51

Vlodification de |’impédance de charge du CA-5EI/CA-5AI/CA-5S1

[he plastic bags contain five resistors

sach for the left and right channels. The

oad impedance when an MC-type

sartridge is used can be altered by

nstalling these resistors on the printed

sircuit boards in the CA-5EI/CA-SAI/

CA-51. (The load impedance is factory-

set to 100 ohms.) When wishing to make this alteration,

contact your dealer. Never attempt to

install the resistors yourself, as opening

the unit involves a considerable risk of

electric shock.

™ Procedure for installing

resistors

Two resistors (one each for left and right

shannel) must be soldered to the circuit

boards, as shown in the illustration. Be

sure to turn the power OFF and unplug

the power cord before opening the unit.

e Select the resistors for the desired

load impedance according to their

color codes, as indicated in the table

on the reverse side.

® Trim the resistor leads as shown on

the reverse side. Then insert the leads

into the gold-plated sockets on the

input section of the MC head amplifier

board and solder each resistor solidly

in place. Make sure that equal resistor

values are used for the two channels.

@ The resistors may be mounted in

either direction.

Die PlastiktGten enthalten je funf

Widerstande fiir rechten und linken

Kanal. Bei Verwendung eines

MC-Tonabnehmers kann die

Lastimpedanz bei Bedarf durch

Anbringen der Widerstande auf den

Platinen des CA-5EI/CA-5A1/CA-51

verandert werden. (Die ab Werk

eingestellte Impedanz betragt 100 Ohm.)

Diese Anpassung darf nur durch

autorisierte Handier durchgefthrt

werden, da bei Eingriffen in das Gerat

Stromschiaggefahr besteht.

@ Einbau

Zwei Widerstande (je einer fur rechten und linken Kanal) mUssen an den dafur

vorgesehenen Stellen auf die

Schaitplatinen geldtet werden, wie in der

Abbildung gezeict.

@ Wahlen Sie die zur Erzielung der

gewlinschten AbschluBimpedanz

erforderlichen Widerstande nach ihrer

Farbkodierung aus, wie in der

umseitigen Tabelle aufgefuhrt.

@ Kirzen Sie die AnschluBdrahte der

Widerstande, wie umseitig gezeigt, und

stecken Sie die Drahte in die

vergoldeten Osen auf der Platine (Eingangsstufe des MC-Vorverstarkers). Loten Sie dann

die Drahte gut an. Achten Sie darauf,

gleiche Widerstandswerte fur beide

Kanale zu verwenden.

@ Die Ausrichtung der Widerstande ist

beliebig.

Les sacs en plastique contiennent

chacun cing résistances pour les canaux

gauche et droit. Lors de l’utilisation d’une

téte de lecture a bobine mobile,

l'impédance de charge peut étre modifiee

en installant ces résistances sur les

circuits imprimés du CA-5EI/CA-SAI/

CA-5I. (L’impédance de charge est

réglée sur 100 ohms a la sortie de

l’usine.) Lorsque vous désirez effectuer cette

modification, contactez votre

distributeur. Ne jamais essayer

d’instailer les résistances par

vous-méme car louverture de cet

appareil peut entrainer de forts risques

d’électrocution.

@ Pour linstallation des

resistances

les 2 resistances (une pour Je canal

gauche et une pour le canal droit) doivent

étre soudées sur /es panneaux des

enceintes. Vérifier que le courant n’est

pas allumeé et que la prise d’alimentation

soit débranchée avant d’ouvrir le

couvercie de l’appareil.

® Choisir les résistances suivant

impedance de charge desiree en

vous aidant des couleurs servant de

repéres, comme indique sur le tableau

ci-apres.

e Regler te bout des resistances comme

indiquée au dos. Insérer ensuite les

bouts dans les supports dores dans la

section d’entrée du pré-amplificateur

et souder chaque resistance

solidement a leur place. Verifier que

les resistances utilisées pour les deux

courants soient de valeur egale.

@ Les resistances peuvent étre montees

dans n’importe quel sens.
