Important Precautions

This symbol is
used to alert the
operator to follow
important operating
procedures and pre­cautions detailed in
documentation.

This symbol is used
to warn operators
that uninsulated
"dangerous volta­ges" are present
within the equip­ment enclosure that
may pose a risk of
electric shock.

1. Save the carton and

packing material
even if the equipment
has arrived in good
condition. Should you

ever need to ship the
unit, use only the origi­nal factory packing.

2. Read all documen-

tation before opera­ting your equipment.

Retain all documentation
for future reference.

3. Follow all instructions

printed on unit chas­sis for proper opera­tion.

4. Do not spill water or

other liquids into or
on the unit, or ope­rate the unit while
standing in liquid.

5. Make sure power

outlets conform to
the power require­ments listed on the

back of the unit.

6. Do not use the unit if

the electrical power

cord is frayed or bro­ken. The power supply

cords should be rou­ted so that they are not
likely to be walked on or
pinched by items placed
upon or against them,
paying particular atten­tion to cords and plugs,
convenience receptacles,
and the point where
they exit from the
appliance.

7. Always operate the

unit with the AC
ground wire con­nected to the electri­cal system ground.

Precautions should be
taken so that the means
of grounding of a piece
of equipment is not
defeated.

8. Mains voltage must

be correct and the
same as that printed
on the rear of the
unit. Damage caused by

connection to improper
AC voltage is not cove­red by any warranty.

9. Have gain controls

on amplifiers turned
down during power­up to prevent speaker

damage if there are high
signal levels at the inpu­ts.

10. Power down &

disconnect units from
mains voltage before
making connections.

11. Do not use the unit

near stoves, heat
registers, radiators,
or other heat produ­cing devices.

12. Do not block intake
or exhaust ports.

Do not operate equip-

ment on a surface or in
an environment which
may impede the normal
flow or air around the
unit, such as a bed, rug,
weathersheet, carpet,
or completely enclosed
rack. If the unit is used
in an extremely dusty or
smoky environment, the
unit should be perio­dically "blown free" of
foreign matter.

13. Do not remove the
cover. Removing the
cover will expose you
to potentially dangerous
voltages. There are no
user serviceable parts
inside.

14. Connecting ampli-

fier outputs to oscil­liscopes or other test
equipment while the
amplifier is in brid­ged mode may damage

both the amplifier and
test equipment.

15. Do not drive the inputs
with a signal level grea­ter than that required to
drive equipment to full
output.

16. Do not connect the

inputs/outputs of
amplifiers or conso­les to any other vol­tage source, such as a

battery, mains source, or
power supply, regardless
of whether the amplifier
or console is turned on
or off.

17. Do not run the

output of any ampli­fier channel back into

another channel's
input. Do not paral­lel-or series-connect
an amplifier output
with any other ampli­fier output. KIND is

not responsible for
damage to loudspeakers
for any reason.

18. Do not ground any
red ("hot") terminal.
For connection of "hot"
terminals to get parallel
high current mode see
appropriate paragraph.

19. Non-use periods. The
power cord of equip­ment should be unplug­ged from the outlet
when left unused for a
long period of time.

20. Service information.
Equipment should be
serviced by qualified ser­vice personnel when:

A. The power supply cord

or the plug has been
damaged;

B. Objects have fallen, or

liquid has been spilled
into the equipment;

C. The equipment has been

exposed to rain;

D. The equipment does

not appear to operate
normally, or exhibits a
marked change in per­formance;

E. The equipment has been

dropped, or the enclosu­re damaged.

21. To obtain service,
contact your nearest
KIND Service Center,
Distributor, Dealer, or
KIND Audio (Italy).

INFORMAZIONI PER LA
GARANZIA

(Solo per l’Italia; Consultate
il vostro Rivenditore o
Distributore)

Esonero

KIND audio, non è responsabile
per danni causati dalla negligenza
oppure dall’ errata installazione
o dall’uso improprio di questo
amplificatore modello DD+
verso altoparlanti, amplificatori o
altro materiale.

Garanzia del prodotto

KIND audio garantisce i model­li DD+ per un periodo di tre
anni (1095 giorni) da difetti dei
materiali e/o costruzione, sosti­tuirà le parti difettose e riparerà
i prodotti malfunzionanti durante
questo periodo, solo quando il
difetto avviene con un uso e una
installazione normale.
L’unità deve essere ritornata alla
nostra fabbrica in porto franco
con allegata fattura o scontrino
fiscale che ne provi l’acquisto.
Questa garanzia prevede un
esame del prodotto ritornato,
per la verifica di eventuali difet­ti di costruzione, il giudizio su

User Responsibility

SPEAKER DAMAGE
Your amplifier is very
powerful and can be
potentially dange­rous to both, loud-

speakers and humans
alike. Many loudspeakers can be
easily damaged or destroyed by
overpowering, especially with the
high power available from a bri­dged amplifier. Always check the
speakers’ continuous and peak
power capabilities. Even if the
amplifier’s front panel attenuators
can be used to reduce the gain,
it is still possible to reach full
output power if the input signal
level is high enough.

HAZARD OUTPUT

VOLTAGES

Power amplifiers are

capable of producing

hazardous output
voltages (on speaker connector).
To avoid electrical shock, do
not touch any exposed speaker
wiring while the amplifier is ope­rating.

RADIO INTERFERENCE
A sample of this product has
been tested and complies with
the limits for the European
Electro Magnetic Compatibility
(EMC) directive. These limits are
designed to provide reasona­ble protection against harmful
interference from electrical equi­pment. This product uses radio
frequency energy and if not used
or installed in accordance with
these operating instructions, may
cause interference to other equi­pment, such as radio receivers.
However, there is no guarantee
that interference will not occur
in a particular installation. If this
equipment does cause harmful
interference to radio or tele­vision reception, which can be
determined by turning the equi­pment on and off, the user is
encouraged to try to correct the
interference by one or more of
the following measures:

•Reorient or relocate the anten­na.

•Increase the separation between
the equipment and receiver.

•Connect the equipment into an
outlet on a circuit different from
that to which the receiver is con­nected.

Responsabilità dell’utente

DANNI AGLI
ALTOPARLANTI
Questo amplificato­re è estremamente
potente e può esse-

re potenzialmente
pericoloso sia per gli altoparlanti
che per l’uomo. La maggior parte
degli altoparlanti può danneg­giarsi o rompersi facilmente, in
particolare a causa della potenza
elevata erogata da un’amplificato­re usato a ponte. Verificare sem­pre la potenza di picco e conti­nua degli altoparlanti. Anche se il
guadagno viene ridotto tramite
gli attenuatori sul pannello fron­tale dell’amplificatore, è ancora
possibile raggiungere la massima
potenza di uscita se il livello del
segnale in ingresso è sufficiente­mente alto.

TENSIONI

IN USCITA

PERICOLOSE

Gli amplificatori sono

in grado di genera­re tensioni di uscita pericolose
(al connettore degli altoparlanti).
Per prevenire il rischio di scossa
elettrica, non toccare gli eventua­li cavi scoperti degli altoparlanti
con l’amplificatore in funzione.

INTERFERENZE RADIO
Un campione di questo prodotto
è stato testato ed omologato in
conformità ai limiti della Direttiva
Compatibilità Elettromagnetica
(EMC). Questi limiti sono stati
definiti per fornire una protezio­ne ragionevole dalle interferenze
pericolose dei dispositivi elettri­ci. Questo prodotto utilizza le
radiofrequenze e, qualora non sia
installato o utilizzato nel rispetto
delle presenti istruzioni per l’uso,
può interferire con altri disposi­tivi, ad esempio ricevitori radio.
Tuttavia, non è garantito che non
si verifichino interferenze in una
particolare installazione.
Qualora il dispositivo interferi­sca con la ricezione di radio o
televisione (tale condizione può
essere verificata accendendo e
spegnendo il dispositivo), l’utente
deve tentare di eliminare l’inter­ferenza adottando una o più delle
seguenti misure:

•Riorientare o spostare l’antenna.

•Aumentare la distanza tra dispo-

sitivo e ricevitore.

•Collegare il dispositivo ad una
presa posta su un circuito dif­ferente rispetto a quella a cui è
collegato il ricevitore.

• Verificare che l’unità interessata
