ATTENTION : Avant de connecter une enceinte NT au secteur,
coupez le signal rrivant en entrée de l'enceinte en réglant le
niveau de sortie de la source au minimum (réglage de niveau
général Master ou tout autre réglage de niveau de sortie).
Dans le cas contraire, le niveau sonore risque d'être excessif,
ce qui peut détruire l'encinte lors de sa mise sous tension.

3.2 Connexions Audio

Connectez la sortie de la source de signal à niveau ligne à
l'entrée XLR femelle 3 broches de la face arrière. Cette entrée
est à symétrie électronique.

3.3 Raccordement au Secteur

PowerCon, située en face arrière de l'enceinte. Connectez
l'autre extrémité à une prise secteur, avec une tension de 115
V 60 Hz ou 230 V 50 Hz, indiquée sur l'enceinte. Si
nécessaire, faites appel à un électricien aréé pour modifier la
fiche secteur en fonction du format utilisé dans votre région.

3

ATTENTION : L'enceinte n'est pas équipée d'un interrupteur secteur. Lorsque l'enceinte est
connectée au secteur, celle-ci est opérationnelle et son niveau est contrôlé pr le signal source
alimentant l'enceinte.

3.4 Référence du Niveau de Sortie

Utilisez un signal source de référence, augmentez progressivement son niveau jusqu'à
obtenir le niveau souhaité en veillant à rester sous le point où la Led d'écrêtage CLIP et/ou
d limitation LIMITER s'allume.

ATTENTION: En absence de son, commencez par diminuer le niveau de sortie de la source
avant de rechercher le problème. Ceci évite la présence de tout niveau sonore excessif et
dangereux dans l'enceinte.

3 Guida Rapida

Se ai già esperienza nell'impiego di diffusori attivi, o se desideri utilizzarlo da subito, questa
Guida Rapida fornisce ogni dettaglio utile per l'impiego dei diffusori NT Series. Per le
istruzioni di questa sezione, fare riferimento alle figure.

3.1 Imposazioni Iniziali dei Controlli

Usa queste regolazioni nominali per gli switches del pannello posteriore.

ATTENZIOE: Prima di collegare il diffusore NT alla presa di
alimentazione, abbassa completamente il livello del segnale
in ingresso, agendo sul controllo di livello d'uscita della
sorgente del segnale (controllo Master Volume o altri
controlli di livello d'uscita. In caso contrario, alimentando il
diffusore potrebbero verificarsi livelli di segnale eccessivi e
potenzialmente pericolosi.

3.2 Connessione Audio

Collega l'uscita di linea della sorgente del segnale all'ingresso
XLR-3F presente nel pannello posteriore Questo ingresso è
bilanciato elettronicamente.

3.3 Connessione di Alimentazione AC

Collega il cavo di alimentazione AC fornito in dotazione al
connettore Neutrik PowerCon presente nel pannello
posteriore del diffusore. Collega l'altra estremità del cav ad una
presa di corrente AC (115 V 60 Hz o 230 V 50 Hz, come

indicato nell'etichetta presente nel diffusore). Se necessario, rivolgersi ad un elettricista
qualificato per cambiare la spina del cavo, in base ai requisiti di compatibilità alle prese
d'alimntazione AC utilizzate nell'area d'impiego.

CAUTELA: Il diffusore non dispone di un interruttore per l'attivazione. Collegando il cavo
di alimentazione alla presa di corrente, il diffusore si attiverà: il livello d'uscita è
controllabile dalla sorgente el segnale.

3.4 Regolare il Livello D’uscita

Con il segnale in esecuzione, aumenta gradualmente il livello della sorgente sonora fino a
raggiungere il volume desiderato, prestando attenzione a non far attivare gli indicatori CLIP
e/o LIMITER.

CAUTELA: S il diffusore non emette alcun suono, assicurati di abbassare il livello d'uscita
della sorgente sonora, prima di investigare sulle cause del problema. In questo modo eviterai
la generazione di eventuali livelli di segnale eccessivi e dannosi da parte deldiffusore.

Section 4 Overview

This loudspeaker is intended for professional use. The construction, components, and hardware
have been designed to provide robust, reliable performance for its intended application.
Please ensure that you fully understand proper installation and operation before use.

4.1 Using the Loudspeaker

You will need to perform the following general tasks to properly put the loudspeaker into
service. The details for each task are provided in this manual.

1. Design and install a rigging or mounting system to support the loudspeaker in its
intended location and aimed in the desired direction.

2. Connect a line level audio signal to the loudspeaker.

3. Connect the loudspeaker to an ac mains supply as specified for the particular model.

4. Set-up and adjust system gain, signal processing, and limiting, as needed to
maximize the loudspeaker's performance.

5. Provide training to operate the loudspeaker within its limits.

6. Provide regular inspection and maintenance to maintain the integrity of the
installation and the performance of the loudspeaker system.

4.2 Description

The NT Series of loudspeakers represents true breakthrough technology with Gunness
Focusing™. In basic form, NT loudspeakers are compact, self-powered, and extremely
lightweight while providing the exceptionally high output capabilities required for
professional applications. However, to complement these features, new DSP (digital signal
processing) technology corrects inherent problems with compression driver phase plugs and
horns as well as the LF drivers. This processing is called Gunness Focusing™ after its inventor
David Gunness, EAW's Director of R&D. Gunness Focusing™, along with the highest quality
amplification, affords sonic performance comparable to the highest quality, direct radiating,
studio monitors but at much higher output levels.

7

NT loudspeakers are designed to meet the requirements and demands of portable
applications as well as permanent installations. The integral electronics are based on proven,
high efficiency amplifier technology, with field-replaceable amplifier modules. The
loudspeakers need to be connected to an ac mains supply and a line level audio signal. The
internal DSP is factory preset to provide correct and consistent performance.

4.2.1 Models

The 2-way NT loudspeakers are available in both 12-inch and 15-inch LF driver formats.
Different beamwidths are offered to meet typical coverage requirements in their intended
applications. The trapezoidal design of the enclosures makes them easy to use as a main PA
loudspeaker or as a floor wedge for stage monitor applications.

A companion NT subwoofer is engineered to complement the NT full-range loudspeakers.
It extends the low frequency response of an NT full-range system and increases the output
capabilities at low frequencies. The drivers are installed so one is facing into the enclosure,
but connected with opposite polarity so both cones move in the same direction. At high
output levels each cone "loads" the other in the opposite direction to smooth out any
mechanical asymmetries. The result is significantly reduced distortion.

NT Models:

4.2.2 Amplification

As is true of all professional loudspeaker systems, the performance of the NT Series
loudspeakers depends on amplifiers delivering an adequate supply of clean power. To
maximize performance, the full-range loudspeakers are bi-amplified, meaning the LF and HF
drivers each have their own signal processing and built-in, high-efficiency amplifier. The
subwoofer is dual-amplified, meaning each driver has its own, built-in, high efficiency
amplifier.

WARNUNG: Lesen und beachten Sie alle Warnungen und Sicherheitshinweise in der

mitgelieferten "EAW Lautsprecher Bedienungsanleitung" bevor Sie das Produkt benutzen.
Nichtbeachtung dieser Hinweise können möglicherweise zu Schäden am quipment oder zu
Verletzungen bzw. zum Tod von Personen führen.

5.1.1 Mounting Point Working Load Limits

Enclosure Oriented Horizontally: NT's integral mounting points and fly tracks are designed
to support only the weight of their own loudspeaker with suitable, external hardware. This
means that each NT loudspeaker must be supported independently of any other NT
loudspeaker and any other loads.

Enclosure Oriented Vertically: NT's integral mounting points and fly tracks are designed to
support two loudspeakers with suitable, external hardware. This means that each NT
loudspeaker can be supported from the fly-tracks of the loudspeaker above it.

5.2 Application Configurations

5.2.1 Full-Range Loudspeaker

The NT loudspeaker is intended for use in several mounting configurations:

Placement in typical loudspeaker locations, such as on
the floor, a stage, a subwoofer stack,
or other stable, solid platform.

9

Placement on shelving designed specifically to support the loudspeaker's weight
with a design factor that meets applicable structural codes and regulations.

• Pole-mounted on an NT Subwoofer or a standard, loudspeaker stand using the
integral pole cup. The pole cup is designed to accommodate 1-3/8 in diameter poles.

• Suspension using the integral, fly-track rigging hardware, EAW accessory double­stud fittings, and user-supplied, external, mounting/rigging fittings that are
suitable for supporting the loudspeaker from structure.

• Wall or ceiling mounted using the integral 5/16-18 mounting points on the enclosure
bottom and a user-supplied Omnimount™ 120.0 Series or similar mounting bracket.

5.2.2 Subwoofer

The NT subwoofer is intended for several mounting configurations:

• Placement or stacked on a floor or the ground. This provides an additional 6 dB
output as these locations are acoustically half-space.

• Placement or stacked on shelving designed specifically to support the subwoofer's
weight with a design factor that meets applicable structural codes and regulations.

5.2.3 Stage Monitor

As a stage monitor, the NT full-range loudspeaker is designed to lay on one of its angled
sides on the floor. The enclosure's trapezoidal shape provides an ideal angle for aiming up
toward performers from a stage floor.

Because of the enclosure's symmetrical shape, you can place the
loudspeakers in a matched left/right pair with both HF horns
inward or outward with respect to the performer. For this
configuration, each loudspeaker must lay on its side opposite the
amplifier module. This means the amplifier module with its
panel for one of the loudspeakers must be moved to the opposite
side of the enclosure from the factory installed position.

5.2.4 Moving the Amplifier Module:

WARNING: Disconnect the ac mains cable before doing this procedure.

Displacement du module d'amplification:

ATTENTION: Déconnectez le cordon du secteur avant d'entamer cette procédure.

Spostare il modulo d'amplificazione:

ATTENZIONE: Prima di procedere con questa operazione, disconnettere il cavo

d'alimentazione AC.

Despazamiento del módulo amplificador:

PRECAUCION: Desconecte el cable de alimentación antes de realizar este proceso.

Ausbau des Endstufenmoduls:

WARNUNG: Ziehen Sie den Netzstecker aus der Steckdose, bevor Sie mit dieser Prozedur beginnen.

10

1. Remove the back panel from one side of the enclosure by removing its 12 retaining screws.

2. Remove the amplifier module from the other side
of the enclosure by removing its 12 retaining screws.

3. Pass the amplifier module through the openings in
the enclosure and position it in place of the blank
panel. You may also disconnect the quick release
connector and move the amplifier outside the
enclosure, reconnecting it through the other opening.

4. NOTE: To keep the input and power cabling close
to the floor when in use, rotate the panel so that
the input connectors are adjacent to the rear
"spine" of the enclosure.

5. Refasten both the blank panel and amplifier
panels, securely tightening all screws.

5.3 Configuring Arrays

NT loudspeakers can be arrayed in various ways. However, arraying loudspeakers requires
special consideration for the overall array's mounting angle, projection pattern,
rigging/mounting method, and for system tuning adjustments. These issues can be
significantly more complex than when the loudspeakers are used singly. For assistance in
configuring NT arrays, contact EAW's Application Support Group.

5.3.1 Center of Gravity

It might seem intuitive that for the NT full-range models, the side of the enclosure with the
amplifier would be heavier. However, the center of gravity for all models is on the left to
right centerline. Thus, when suspending NT loudspeakers, there is no weight or balance
advantage to moving an amplifier module as described in Section 5.2.4.

5.3.2 Vertical Array

1. Orient the enclosures so the LF drivers are adjacent (i.e. enclosure bottom to bottom).

2. Use a 45° splay between the enclosure "bottoms".

3. Set the MODE switch for each loudspeaker to COUPLED.

5.3.3 Horizontal Array

NOTE: It may be desirable to move an amplifier module as described in section 5.2.4
so the enclosures are symmetrical left to right. This can facilitate running cabling and/or
help hide cabling from audience view.

Enclosures Vertical

1. NT26 and NT56: use a 60° splay between the enclosure sides.

2. NT29 and NT59: use a 90° splay between the enclosure sides.

3. To avoid interference with the input and ac mains connections, move the amplifier
module to the opposite side of one or both of the enclosures. See Section 5.2.4.

4. Set the MODE switch for each loudspeaker to COUPLED.

11

Enclosures Horizontal

1.Orient the enclosures so the LF drivers are adjacent
(i.e. enclosure bottom to bottom).

2. Use a 45° splay between the enclosure "bottoms".

3. Set the MODE switch for each loudspeaker to COUPLED.

Section 6 Electrical Installation

For the instructions in this section, refer to the accompanying Figures.

6.1 Audio Signal Connection

Connect the audio signal to the loudspeaker BEFORE connecting the loudspeaker to the ac
mains supply.

WARNING: Before connecting an NT loudspeaker to the ac mains supply, completely turn
down the input signal to the loudspeaker using the signal source's output level (master
volume control or other output level control). If not, there could be excessive and possibly
ear-damaging sound levels from the loudspeaker when energized.

Connecxion du Signal Audio

Connectez le signal audio à l'enceinte AVANT de connecter l'enceinte au secteur.

ATTENTION: Avant de connecter une enceinte NT au secteur, coupez le signl arrivant en
entrée de l'enceinte en réglant le niveau de sortie de la source au minimum (réglage de
niveau général Master ou tout autre réglage de niveau de sortie). Dans le cas contraire, le
niveau sonore risque d'être excessif, ce qui peut causer des ésions auditives irréversibles lors
de la mise sous tension de l'enceinte.

Conneccione del Segnale Audio

Collega il segnale audio al diffusore PRIMA di collegare il diffusore all'alimentazione AC.

ATTENZIONE: Prima di collegare il diffusore NT alla prsa di alimentazione, abbassa
completamente il livello del segnale in ingresso, agendo sul controllo di livello d'uscita
della sorgente del segnale (controllo Master Volume o altri controlli di livello d'uscita). In
caso contrario, alimentando il diffusore potrebbero verificarsi livelli di segnale eccessivi e
potenzialmente pericolosi.

Conexion de la Señal Audio

Conecte la señal audio al altavoz ANTES de conectar el altavoz a la salida de corriente.

PRECAUCION: Antes de conectar uno de estos altavoces N a la salida de corriente, reduzca
al mínimo o anule la señal de entrada que va a estos altavoces usando el nivel de salida de
la fuente de señal (control de volumen master u otro control de nivel de salida). En caso
contrario, podrían llegar a producirseniveles de sonido excesivos y posiblemente dañinos
en el momento de encender los altavoces.

12

Audiosignalverbindung

Schließen Sie das Audiosignal am Lautsprecher an, BEVOR Sie den Lautsprecher an das
Stromnetz anschließen.

WARNUNG: Stellen Sie das Ausgagssignal der Signalquelle (z.B. Masterregler eines
Mischpultes) auf den kleinsten Wert, bevor Sie den NT Lautsprecher an das Stromnetz
anschließen. Da dieses Signal zum Lautsprecher geschickt wird, könnten bei starkem
Quellsignal extrem bzw. schädliche Asgangspegel von der Box produziert werden, wenn
diese mit Netzstrom versorgt wird.

6.1.1 Input Panel

The audio input connection to the loudspeaker can be
made to either the female INPUT or male LOOP
connector on the rear of the loudspeaker. Normaly, the
female connector is used for the input signal. Connect
the output from your signal source (mixing console,
microphone preamp, or other line-level source) to either
XLR-3 connector. This is an electronically balanced input
designed to be connected to a balanced signal source.

Pin Connection

1 shield
2 signal plus or cold
3 signal minus or hot

6.1.2 Loop Connector

The Loop connector is hard-wired to the Input connector and thus carries the identical signal.
This connector is used to "daisy-chain"the input signal to multiple NT loudspeakers and NT
subwoofers. Because the signal processing, including the crossover, is built in, full-range
loudspeakers and subwoofers may be daisy-chained together from a single signal source.

NOTE: To avoid potential interference, do not leave an un-terminated cable attached to
either the Input or the Loop connector.

6.2 System GAIN

6.2.1 Level Control

The electronic sensitivity and gain in all full-range NT models is fixed by design. There are
no adjustable, input level controls. This means that whenever the loudspeaker is connected
to the ac mains and provided with audio signal the output level is always controlled
externally to the loudspeaker. This way, there is no question about a misadjusted level
control on the loudspeaker. This also largely prevents overdriving the equipment directly
upstream of the loudspeakers.

The sensitivity is designed to match with a wide range of professional line level audio
equipment with nominal operating levels of 0 dBu (= 0.775 V). Consumer equipment has
nominal operating levels of 8 dB to 10 dB below 0 dBu. If used with the latter equipment,
it may not be possible to reach full output before clipping upstream equipment. In such
cases, there are 3rd party devices available that can be inserted into the signal path to match
the impedance and level between consumer and professional equipment.

6.4 Operating Controls - Full Range Loudspeakers

For the instructions in this section, refer to the accompanying Figure.

These switches electronically configure the loudspeaker for use with and without a
subwoofer and for different mounting positions.

NOTE: The recommendations given are general guidelines and cannot address all
applications or loudspeaker configurations. Use measurements and listening tests to
determine the best setting for a particular situation.

6.4.1 Setting the HPF (High Pass Filter)

The HPF switch sets the low frequency roll-off frequency or the system. This means that,
below the roll-off frequency, the lower the frequency the more the attenuation is applied to
the input signal.

Recommended Use:

55 Hz (switch to left):
Without Subwoofer:

Provides normal low frequency response for
music or a combination of music and speech.

With Subwoofer:
Not recommended. This will cause excessive
energy between 55 Hz and 110 Hz.

110 Hz (switch to right):
With Subwoofer:

Provides normal acoustic integration with a
subwoofer.

Without a Subwoofer:
Recommended for speech only; not
recommended for music.

6.4.2 Setting the Operating Mode

The Mode switch sets the voicing of the loudspeaker for different applications. It
compensates for differences in performance caused by different mounting conditions with
a LF shelving filter in the coupled position. The filter reduces the LF output in the range of
frequencies affected by 1/2 space loading.

Recommended Usage:

Normal (switch to left):
Use when the loudspeaker is aimed at the audience, typically stacked on stage or
stand/pole mounted.

Coupled (switch to right):
Use when the loudspeaker is coupled to a surface such as the stage floor as a performer
monitor or when mounted on a wall or the ceiling.

Use when arrayed with other NT loudspeakers to attenuate excess energy caused by
mutual coupling.

Use when room acoustics are "live", meaning with higher reverberation times, to improve
intelligibility by reducing the amount of LF reverberant energy excited by the loudspeaker.

6.5 Operating Controls - Subwoofer

For the instructions in this section, refer to the
accompanying Figure.

These switches electronically configure the
subwoofer for use with a full-range
loudspeaker depending on the subwoofer's
positioning relative to the full-range
loudspeaker.

NOTE: The recommendations given are
general guidelines and cannot address all
applications or loudspeaker configurations.
Use measurements and listening tests to
determine the best setting for a particular
situation.

6.5.1 Setting the Gain Switch

The gain switch adjusts the input to 0 dB or +6 dB gain.

0 dB (switch to left)
Use for the common situation where the subwoofer is floor-mounted and the
full-range loudspeaker is pole or stand mounted above it.

+6 dB (switch to right)
Use when more subwoofer level is needed, such as when both the full-range and
subwoofer are suspended.

For situations where a wider range of gain control is needed, use either of these
recommended methods.

1. Provide a separate signal feeds to the full-range and subwoofer, each feed having its
own level control. This is normally accomplished using separate auxiliary or matrix
outputs on a mixing console

2. Provide an external attenuator to the loudspeaker that needs less gain. This can be
a fixed resistive attenuator, ideal for permanent installations. Where frequent
adjustment may be needed, such as in a portable system, an adjustable level control
may be inserted into the signal line to the loudspeaker needing less gain. A 20k ohm
to 40k ohm potentiometer with an audio or log taper can provide the desired results.

6.5.2 Setting the Polarity

Recommended usage:

Normal (switch to left)
Use to provide normal integration with a full range loudspeaker that is either stacked
on top of or pole mounted to the subwoofer.

Invert (switch to right)
Use when the sound of the subwoofer and full-range loudspeaker do not integrate well,
meaning there is bass loss in the listening area. This is usually caused when the subwoofer
is located at a different distance to the listeners than the full-range loudspeaker or
because of destructive room reflections. Given the unpredictability of low frequency
response in a room, the Polarity setting may or may not improve the results. In some
cases, there may be a difference in the results, but not a better or worse result.

Section 7 Operation

7.1 Operating Limits

7.1.1 Operator Responsibility

It is the responsibility of the audio system operator to operate the loudspeaker within its
capabilities. This is the only way to ensure that the loudspeaker is not stressed beyond its
limits to the point of damage or failure. Refer to the EAW Loudspeaker Manual for detailed
Operating instructions and suggestions. NT's LED status indicators will show when the
loudspeaker is operating at or beyond its maximum capabilities.

7.2 Adjusting the Output Level

With a source program playing, gradually turn up the level of your signal source until the desired
volume is reached or until the CLIP light flashes only occasionally, whichever comes first.

7.3 Operating Indicators

For the instructions in this section, refer to the
accompanying Figures.

7.3.1 Limiter Active

The limiting parameters set in NT's DSP are
engineered to provide a high level of protection for
the transducers while maximizing sonic
performance and output. A Limiter Active indicator
in the rear input panel illuminates when limiting is
occurring. If this is flashing occasionally, meaning
no more than once every 3 seconds or so, then
levels are probably OK, but at maximum. If this
indicator is flashing more than once every 3
seconds or so, reduce the input signal level.

7.3.2 Clip

A Clip indicator on the rear panel illuminates if any
of NT's electronics are being driven into clipping.
This includes the entire signal chain from the input
stage through the DSP. Clipped signals can more
easily damage transducers as they can raise the
average signal level significantly with a spectrum
that differs significantly from the input signal.

7.3.3 IMPORTANT: Operator Response

If either or both of the Limiter Active and Clip indicators are flashing occasionally, meaning
no more than once every 3 seconds or so, then the signal level may not be excessive.
However, this is a CLEAR indication the loudspeaker is being operated near or at its
maximum limits. If either or both of these indicators are flashing more than once every 3
seconds or so, or are on steadily, reduce the input signal level or damage to the drivers is
likely to occur.

CAUTION: Electronic limiters cannot provide absolute protection against driver failure.
Thus, if limiting is occurring, it is a warning that excessive signal levels are being
approached. It is NOT an indication that the loudspeaker is successfully protecting itself.

19

7.3.4 Amplifier Status

An Amplifier Status indicator monitors the status of each of the two amplifiers in the full­range and subwoofer models. If illuminated Green, the amplifier status is Normal. If
illuminated Red, a protection circuit has activated and the amplifier is in Fault status.

The causes for a Fault indication can be:

• Amplifier overheating

• Power supply overheating

• Excessive amplifier output current

• Excessive power supply current

• Low ac mains voltage

• Low amplifier output voltage

• Electronic failure

To minimize audio downtime or operation at reduced levels, the protection circuits will
automatically reset after the fault condition is lowered to an acceptable level or removed.
The only exception is protective shut-down due to electronic failure.

7.3.5 Signal Present

The Signal Present indicator illuminates when an audio signal greater than 30 dBu (25 mV)
is present at the input connector.

7.4 Signal Processing

7.4.1 Internal Signal Processing

The NT Series incorporates sophisticated, digital signal processing to optimize performance
and reliability. Normally, no external signal processing is required. The internal processing
will provide excellent results in a variety of venues. The processing was determined from
extensive laboratory measurements and field testing to provide the maximum performance
in terms of frequency response, phase response, power handling, and audio quality. It affects
many aspects of the loudspeaker's performance including frequency response, beamwidth
consistency, output level capability, and wavefront coherency.

7.4.2 External Signal Processing

In some applications, external signal processing may be used because of room acoustics,
audio program content, or personal taste. In such cases, use standard analog or digital
equalizers. Avoid radical settings as these can alter the performance in adverse ways not
readily apparent, such as reducing power handling or altering the beamwidth.

7.4.3 Limiters

NT loudspeakers have built-in, factory set limiting. The limiter characteristics and settings
were determined to provide the maximum protection possible, to minimize the sonic effects,
and to integrate closely with the amplifier capabilities. Defeating such limiting by using an
external limiter could expose the drivers or amplifiers to operation beyond their limits.

External limiting should only be used to limit the maximum output to some level below that
allowed by the factory limiting. In this case, choose limiter settings that minimize the sonic
effects when the limiting is active.

If excessive ac mains input current is detected, an internal fuse will blow. This can occur for
a variety of reasons, such as internal failure, excessive ac mains voltage, or excessive
amplifier output levels. If the fuse blows, have a technician replace it with the identical type
of fuse.

In the unlikely event the fuse blows again, internal failure is indicated, requiring
troubleshooting and repair by a qualified service technician. Do not attempt further use of
the loudspeaker until such repairs are made.

8.3 Field Troubleshooting

8.5 Amplifier Service

WARNING: Disconnect the ac mains cable before doing this procedure.
ATTENTION: Déconnectez le cordon du secteur avant d'entamer cette procédure.
ATTENZIONE: Prima di procedere con questa operazione, disconnettere il cavo

d'alimentazione AC.

PRECAUCION: Desconecte el cable de alimentación antes de realizar este proceso.
WARNUNG: Ziehen Sie den Netzstecker aus der Steckdose, bevor Sie mit dieser Prozedur beginnen.

Faulty electronics are serviced by replacing the entire amplifier module.

8.5.1 Amplifier Modules

There are two types of NT amplifier modules:
one for the NT full-range models and one for the subwoofer.

1. Full-range: Input, DSP, 1000 W @ 4 ohm LF amplifier, 500 W @ 4 ohm
HF amplifier, and power supply.

2. Subwoofer: Input, DSP, two 1000 W @ 4 ohm amplifiers, and power supply.

For the NT full-range models (NT2x & NT5x), each amplifier module has the DSP settings
for all models stored in on-board memory. The active settings are determined by on-board
dip switch settings. Thus,amplifier modules for the full-range models are interchangeable
by simply resetting the dip switches for that particular model.

8.5.2 NT Amplifier Replacement Modules and Dip Switch Settings

An amplifier replacement module consists of the power amplifiers, DSP board, power
supply, connectors, and indicators; all pre-mounted on the amplifier panel.

Amplifier Module Replacement Part Numbers & Dip Switch Settings
NOTE: If the incorrect DIP switch position is used, poor/incorrect performance will result,
at best sounding bad, at worst causing equipment failure.

8.5.3 Replacing the Amplifier Module

1. Remove the amplifier module from the other side of the enclosure by removing its12

retaining screws.

2. Disconnect the quick release connector for the transducer cabling.

3. Configure the replacement amplifier for the NT model by setting the dip switch. See

the chart in Section 8.5.2 for the correct settings. The dip switch is located behind the
input receptacles on the backside of the amplifier module.

4. Once the dip switch is programmed, connect the transducer cabling to the

replacement module.
