USER MANUAL

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 documenta-

tion 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 fan

intake or exhaust
ports. Do not operate

equipment 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 out-

put 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 unusued 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 protect

LED's remain continuou­sly illuminates;

E. The equipment does not

appear to operate nor­mally, or exhibits a
marked change in
performance;

F. 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).

Introduction

Congratulations on your purcha­se of a KIND audio power ampli­fier. We would like to thank you
for your confidence in us and
our products. The power ampli­fier was hand-made in Italy. All
the components were specially
selected. Although the amplifier
was designed to allow strai­ghtforward and uninterrupted
operation, improper handling or
incorrect installation could
damage the power amplifier. Your
amplifier represents the latest
technology in power amplifier
design. Please read this manual
carefully as it contains informa­tion vital to the safe operation of
your amplifier.

Unpacking

Check the carton box and its
contents immediately to see if
there is any sign of damage.
Upon unpacking inspect the
amplifier, if you detect any dama­ge inform the forwarding agent
without delay and ask for the
damage to be documentated.
Claims can only be made against
the forwarder agent by the con­signee. Be sure to save the car­ton and all packaging materials
for the carrier's inspection.
It's a good idea to save the car­ton and packing material even if
the amplifier has arrived in good
condition. Should you ever need
to ship the unit back to KIND,or
one of its Service Center.
Using only the original factory
packaging will be the best way to
save the unit from carrier negli­gence.

Installation/Mounting

All NWX models amplifiers are
3-rack space units that can
mount in a standard 19" rack.
Four front panel mounting holes
are provided. Rear mounting ears
give additional support especially
important in mobile sound
systems.

The unit should not to be installed
in a location with:

•Too high ambient temperatures,
dust build-up or excessive humi­dity;

•Fog machines output’s oriented
to the fan’s input area of the
amplifier;

•Exhaust air ventilators and simi­lar units near the fan's input area
at the rear of the amplifier;

•With permanent vibrations;

•With excessive induction or
magnetic fields due to tranfor­mers and transmitters;

Introduzione

Congratulazioni per il vostro
acquisto di un'amplificatore di
potenza audio KIND. Noi voglia­mo ringraziarvi per la fiducia che
date a noi e ai nostri prodotti. Il
vostro amplificatore é stato
costruito a mano in Italia. Tutti i
componenti sono stati seleziona­ti. Sebbene l'amplificatore é stato
progettato per permettere il fun­zionamento continuo, l'uso
improprio o un'installazione
scorretta potrebbero danneggiar­lo. Il vostro amplificatore rappre­senta la tecnologia più avanzata
nel progetto di un'amplificatore
di potenza. Vi preghiamo leggere
questo manuale attentamente
siccome contiene informazioni
vitali per un utilizzo sicuro del
vostro amplificatore.

Disimballaggio

Controllate l'imballo in cartone e
il suo contenuto immediatamen­te per vedere se ci sono segni di
danneggiamento. Dopo il disim­ballaggio ispezionate l'amplifica­tore, se verificate qualche danno
informate lo spedizioniere senza
ritardo e chiedete che il danno
venga documentato. I reclami allo
spedizioniere possono essere
fatti solamente dal destinatario.
Assicuratevi di conservare l'im­ballo completo per l'ispezione
dello spedizioniere. E' buona idea
conservare l'imballo completo
anche se l'amplificatore arriva in
condizioni ottimali, potreste
averne bisogno per rispedirlo a
KIND o a uno dei suoi Centri
Assistenza. Usate solamente l'im­ballo originale, sarà il miglior
modo per salvaguardare l'appa­recchiatura dalla non curanza
degli spedizionieri.

Installazione/Montaggio

Tutti i modelli di amplificatori
NWX sono 3 unità, possono
essere montati in un rack 19"
standard, sono previsti 4 fori sul
pannello frontale per il montag­gio. Per avere un fissaggio ottima­le, importante nei sistemi mobili,
supporti addizionali sono presen­ti sul retro.

L’unità non dovrebbe essere instal­lata in posti con:

•Temperatura in ambiente trop­po alta, troppa polvere o eccessi­va umidità;

•L’uscita di macchine del fumo
orientata nell’area d’ingresso
della ventola sul retro dell’ampli­ficatore;

•Ventilatori di scarico e simili
unità vicino all’area d’ingresso
della ventola sul retro dell’ampli­ficatore;

•Con vibrazioni permanenti;

•Con eccessiva induzione dovuta
al campo magnetico di trasfor­matori e trasmettitori;
