INTRODUCTION
Thank you for purchasing a NEXT-proaudio I Series speaker. This manual will provide you with useful and
important information about your installation series element. Please devote some time reading this manual,
and keep it at hand for future reference. NEXT-proaudio is concerned with your safety and well-being, so please
follow all instructions and heed all warnings. Also, a better understanding of some specic features of the
speaker will help you to operate it to its full potential. With a continuous evolution of techniques and stan-
dards, NEXT-proaudio, reserves the right to change the specications of its products without early warning. For

UNPACKING
NEXT-proaudio I Series are built under quality supervision of NEXT-proaudio, according to the highest
standards. When unpacking your element, carefully examine it for any signs of possible transit damage and
inform your dealer immediately if any such damage has occurred.
It is suggested that you retain the original packaging so that the cabinet can be repacked in the future if
necessary. Please note that NEXT-proaudio and its authorized distributors cannot accept any responsibility for
damage to any returned product through the use of non-approved packaging.
I SERIES OVERVIEW
The I Series range comprehends the I4, a 4” LF transducer and a 0.8“ Dome Tweeter, the I6, a 6” LF driver
with a 1“ HF Driver, and nally the I8 composed by a 8” LF transducer with a 1“ HF Driver.
The whole series ‘ speakers are housed in a stylish weatherproof plastic cabinet (IP65 - using the back
cover) providing an excellent architectural integration, both indoor and outdoor.
This speaker is an ideal solution for PA applications in restaurants, bars, malls or conferences. The very
accurate speaker’s coverage allows the people, among the audience, to perceive the sound in the same way.
For even greater versatility, the whole series’ speakers can be used at 100V or 16. In high-impedance
(100V) operation, a multi tap transformer is available with 3 dierent taps.
I SERIES ACCESSORIES
All the speakers from I Series come with a U-Bracket included on the packaging. All the U-Brackets are
made from Steel with a Hot-dip Galvanization, coating the steel with a layer of zinc, turning it resistant to corro-
sion.
Other wall brackets (with pan and tilt) are available for I4 and I8 speakers.

SAFETY FIRST
• The speaker is protected against dust and splash water (only with back cover on) thus can be used in
outdoor areas (IP65). DO NOT IMMERSE THE PRODUCT IN WATER, THIS WILL DESTROY IT.
• Never place your speaker in a way that prevents air ow near to the side bass reex ports. A minimum clear-
ance distance of 10cm should be kept between the ports and any near surface.
• Never use your speaker too close to any heat source, such as radiators, or any other device that produces heat.
Recommended temperature: -5ºC to +45ºC.
• Place cables in a way that they do not present a trip hazard.
• Do not place any objects on top of the speaker, they can fall accidentally and cause injuries.
• Do not attempt to move the speaker while connected.
• Do not attempt to service the speaker beyond what is described in this manual. All other service or repair of
this product should be carried only by qualied personnel.
• To prevent electric shock, do not use any extension cord, receptacle or other outlets where the blades of the
connectors cannot be fully inserted.
• Do not operate the unit for an extended period of time with the sound distorting.
• When connecting several speakers, make sure that all the speakers have the same polarity and that the ampli-
er is not overloaded.
• Adjust the rotary switch to the desired power rating for the 100V operation or select the 16Ω position, for
directly operating the speaker at a low-impedance amplier output.
RIGGING AND SUSPENSION SAFETY CONSIDERATIONS
• Before rigging or suspending Install series systems, inspect all components and all hardware for any signs of
damaged or missing parts. If you nd any damaged, corroded or deformed parts, do not use them, replace
them immediately.
• Use only the recommended NEXT-proaudio wall brackets. Doing otherwise may cause the element to fall off,
resulting in personal injury.
• Install the unit only in a location that can structurally support the weight of the unit and the mounting brack-
et. Doing otherwise may cause the element to fall off, resulting in personal injury and/or property damage.
• Use nuts and bolts that are appropriate for the wall's materials and structure. Doing otherwise may cause the
element to fall off, resulting in personal injury and/or property damage.

GETTING STARTED
CONNECTIONS
The I Series speakers are equipped with a 4-positions Phoenix
connector located on the back plate. The rst two pins correspond
to IN- / IN+, and the last two pins are Link- / Link+, internally linked
to the input sockets.
To connect the speaker, rstly unscrew the two silver screws
and remove the plug. Screw the wires to the plug and re-attach it to
the speaker.
The screw connector provides a faster and easier way to wire
the system allowing the speaker to perfectly t the wall shape
while keeps invisible.
100V TAP SELECTOR
Every speakers from I Series are equipped with a multi-tap
100V transformer. There is a rotary selector placed on the back
panel, near the connections plug. On this section the user can nd
ve dierent switch positions according to the pretended 100V
power and impedance needed. The rst three positions are related
to 100V, the fourth position shuts the speaker OFF - no sound will
come from the speaker - the last position is meant to be used on
low impedance operation (16).
To change the switch position a at screwdriver is recommended.
On the I4, the selectable power taps are 10W, 20W and 40W.
On the I6, the available power taps are 20W, 40W, and 80W.
On the I8, the available power taps are 37.5W, 75W, and 150W.
BACK COVER
Before exposing the speaker to rain or highly humid environ-
ments, please make sure that back cover is correctly installed and
the cable gland is rmly screwed on.
Adjust the power tap before applying the back cover.
Note:
The IP65 can only be achieved when the back cover is in place.

SERVICE
TROUBLESHOOTING
Simple troubleshooting does not require sophisticated measurement equipment and can be easily under-
taken by users. The technique should be to segment the system in order to identify the faulty system compo-
nent. A simple sweep with a sine wave generator can be very helpful though it MUST be made at a fairly low
level to prevent damage to the speakers. A sine wave sweep can help nd:
• Vibrations due to loose screws.
• Air-leak noises: check that no screws are missing, particularly where the accessories attach to the cabinet.
• Vibrations due to a front grille badly positioned on the quick release xings.
• Foreign object that has fallen into the cabinet after repair or through the ports.
• Internal connection wires or absorbing material touching the loudspeaker diaphragm
