SERVICING NOTES
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
CONFIRMING THE OPERATION (E and Indian models)
Please confirm the car audio unit works even if REM output is not
connected when you connect this unit with the car audio unit by
the HIGH LEVEL input.

Notes
ˎWhen using passive crossover networks in a
multi-speaker system, care must be taken as the
speaker system’s impedance should not be lower
than that of the suitable impedance for this unit.
ˎWhen you are installing a 12 decibels/octave
system in your car, the following points must be
considered. In a 12 decibels/octave system where
both a choke and capacitor are used in series to
form a circuit, great care must be taken when they
are connected. In such a circuit, there is going to be
an increase in the current which bypasses the
speaker with frequencies around the crossover
frequency. If audio signals continue to be fed into
the crossover frequency area, it may cause the
amplifier to become abnormally hot or the fuse to
blow. Also if the speaker is disconnected, a
series-resonant circuit will be formed by the choke
and the capacitor. In this case, the impedance in the
resonance area will decrease dramatically resulting
in a short circuit situation causing damage to the
amplifier. Therefore, make sure that a speaker is
connected to such a circuit at all times.

Notas
ˎAl utilizar redes de cruce pasivas en un sistema con
múltiples altavoces, es necesario asegurar que la
impedancia del sistema de altavoces no sea inferior
al valor de impedancia adecuado para esta unidad.
ˎAl instalar un sistema de 12 decibelios/octava en un
automóvil, hay que tener en cuenta los siguientes
puntos. En un sistema de 12 decibelios/octava
donde se emplea una bobina de choque y un
condensador en serie para formar un circuito, hay
que tener mucho cuidado al conectarlos. En los
circuitos de este tipo, se produce un aumento de la
corriente que pasa por alto el altavoz con
frecuencias próximas a la frecuencia de cruce. Si las
señales de audio siguen enviándose a la zona de
frecuencia de cruce, puede producirse un
sobrecalentamiento anormal del amplificador o
puede fundirse el fusible. Además, si se desconecta
el altavoz, se formará un circuito de resonancia en
serie compuesto por la bobina y el condensador. En
este caso, la impedancia del área de resonancia
disminuirá considerablemente, dando lugar a una
situación de cortocircuito y dañando el altavoz. Por
tanto, es necesario asegurar que haya un altavoz
conectado a un circuito en todo momento.
For details on the values of C1, C2, L, refer to
“Table of crossover values for 6 dB/octave”.
Para obtener más información sobre los valores
de C1, C2 y L, consulte la “Tabla de valores de
cruce para 6 dB/octava”.

Ligações
Cuidados
ˎAntes de fazer qualquer ligação, desligue o
terminal de massa da bateria do automóvel
para evitar curtos-circuitos.
ˎVerifique se as colunas utilizadas têm uma
potência nominal adequada. Se utilizar colunas
de baixa capacidade, pode danificá-las.
ˎEste amplificador é um amplificador de fase
invertida.
ˎNão ligue o terminal ¾ do sistema de colunas
ao chassis do automóvel nem o terminal ¾ da
coluna direita ao terminal da coluna esquerda.
ˎInstale os cabos de entrada e de saída longe do
cabo de alimentação porque se estiverem muito
perto podem gerar interferências.
ˎEste aparelho é um amplificador de grande
potência. Como tal, pode não conseguir
utilizá-lo com a potência máxima se usar os
cabos para colunas fornecidos com o
automóvel.
ˎSe o automóvel estiver equipado com um
computador de bordo para navegação ou para
outra finalidade, não retire o fio de ligação à
massa da bateria do automóvel. Se desligar o
fio, apaga a memória do computador. Para
evitar curtos-circuitos quando fizer as ligações,
ligue o cabo de ligação à corrente de +12V
somente depois de ligar todos os outros cabos.

Instalação
(Ȑ)
Antes de fazer a instalação
ˎVerifique se ligou o cabo do telecomando do
autorrádio ao terminal para telecomando.
ˎQuando utilizar um autorrádio sem saída para
telecomando no amplificador, ligue o terminal de
entrada para telecomando (REMOTE) à fonte de
alimentação para acessórios.
ˎUtilize um cabo de ligação à corrente com um
fusível incorporado (25 A).
ˎTodos os cabos elétricos ligados ao borne positivo
da bateria devem ter um fusível a uma distância de
450 mm do borne da bateria e antes de passarem
por qualquer parte metálica.
ˎVerifique se os cabos da bateria ligados ao
automóvel (ligação de massa ao chassis)*2 têm uma
medida pelo menos igual à do cabo principal que
liga a bateria ao amplificador.
ˎDurante o funcionamento com potência total, o
sistema é percorrido por uma corrente superior a
25 A. Assim, verifique se os cabos que vai ligar aos
terminais +12V e GND deste aparelho têm um
calibre superior a 14 (AWG-14) ou uma secção
transversal superior a 2 mm2.

Notas
ˎSe utilizar redes de cruzamento passivas num
sistema com várias colunas, é preciso assegurar-se
de que a impedância do sistema de colunas não é
inferior ao valor de impedância adequado para este
aparelho.
ˎSe instalar um sistema de 12 decibéis/oitava no
automóvel, é preciso ter em atenção os seguintes
pontos. Num sistema de 12 decibéis/oitava em que
se utiliza uma bobina de choque e um condensador
em série para formar um circuito, é preciso ter
muito cuidado ao ligá-los. Neste circuito, vai haver
um aumento na corrente que passa na coluna,
atingindo frequências muito próximas da
frequência de cruzamento. Se continuarem a ser
enviados sinais de áudio para a zona de frequência
de cruzamento, o amplificador pode sobreaquecer
ou pode rebentar um fusível. Além disso, se
desligar a coluna, forma-se um circuito de
ressonância em série composto pela bobina de
choque e pelo condensador. Neste caso, a
impedância na zona de ressonância diminui
drasticamente, dando lugar a uma situação de
curto-circuito e danificando o amplificador. Assim,
tem de haver sempre uma coluna ligada a este
circuito.
