9. Supports and trolleys
The equipment should be only used on trolleys or supports, where necessary, that are
recommended by the manufacturer. The equipment / support / trolley assembly must be
moved with extreme caution. Sudden stops, excessive pushing force and uneven floors may
cause the assembly to overturn.
10. There are numerous mechanical and electrical factors to be considered when installing
a professional audio system (in addition to those which are strictly acoustic, such as sound
pressure, angles of coverage, frequency response, etc.).
11. Hearing loss
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level
that leads to hearing loss is different from person to person and depends on the duration
of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure,
anyone who is exposed to these levels should use adequate protection devices. When a
transducer capable of producing high sound levels is being used, it is therefore necessary
to wear ear plugs or protective earphones. See the manual technical specifications to know
the maximum sound pressure level.
IMPORTANT NOTES
To prevent the occurrence of noise on line signal cables, use screened cables only and avoid
putting them close to:
Equipment that produces high-intensity electromagnetic fields. Power cables. Loudspeaker lines. -
Place this product far from any heat sources and always ensure an adequate air circulation around it.
Do not overload this product for a long time. Never force the control elements (keys, knobs, etc. ). Do not use solvents, alcohol, benzene or other volatile substances for cleaning the external parts of this product.

CABINETS
The NX Series - a new line of active loudspeakers specifically designed to be the everyday
tool for rental companies and professional musicians. With its ultra compact design and
choice of formats, together with high output levels, NX Series is the answer to a wide
variety of production requirements. The NX is reliable, easy to use and versatile: for every
rental company, musician, venue and audio/visual provider, this high-performance selfpowered speaker system offers a degree of simplicity unmatched by traditional amp and
speaker PA systems.
NX Series is a practical solution for high intelligibility speech and audio applications, covering
infill or delay, production studios, presentations and high power music sound reinforcement
with or without subwoofers. A key requirement for everyday audio systems, delivering
simple ‘plug and play’ solutions, without compromising performance and portability.
Legendary RCF transducer technology coupled with state of the art digital amplification
topology resulting in a perfectly optimised loudspeaker series.
The NX Series provides high end audio coverage even at extreme sound pressure levels,
unmatched reliability and acoustic compatibility across the whole series.
The NX Series offers a wide range of practical mounting hardware, to cover all aspects of
system integration, which assist in the overall simple and effortless system set-up, redefining
the high performance portable PA.
All the transducers in the NX Series speakers feature light weight neodymium magnets in
order to guarantee a better performance and make for easier transportation.
All Compression drivers and Transducers are precision built taking advantage of RCF’s
superior moulding, assembly technologies and a wealth of professional knowledge and
experience dedicated to achieving extremely high standards.
All NX Series two-way speakers are equipped with a new generation of 750 Watt Digital
Amplifiers, 500 Watt for the woofers and 250 Watt for the compression drivers. The result
of this is very high output, extremely low distortion and an incredible natural sound.
Each amplifier presents both XLR/jack (Combo) balanced inputs, XLR output link, volume,
EQ Mode (Flat/Boost), a special stage monitoring equalisation set up.
The amplifier features a solid mechanical aluminium structure which not only stabilize the
amplifier during transportation but also assist in the heat dissipation.
All the NX Series amplifiers presents PFC power supply section in order to produce maximum
output even in case of tension drops from main supply.
The new loudspeaker design looks aggressive whilst retaining familiar Art ergonomics and
is the result of extensive combined functional and acoustic research.
The NXM two-way system cabinets are manufactured in Baltic birch plywood and are
designed to dampen down vibrations even at maximum volume settings. The reflex porting
has been resized to offer a better efficiency. The NXM10-A model is equipped with a side
aluminium handle with rubber handgrip for greater portability; the bigger models have 2
ergonomically designed forged aluminium handles with rubber handgrip on the side. At the
bottom a rugged steel pole mount has been installed in all models.
The new cabinet shape will allow every NXM model to be used in the standard configuration
as well as in stage monitor mode. Six fly-track inserts are provided for various rental and
installation applications.

JACK/FEMALE XLR INPUTS (BAL/UNBAL). The system accept jack or XLR
input connectors.
LIMITER LED. The amplifier has a built in limiter circuit to prevent clipping of
the amplifiers or overdriving the transducers. When the soft clipping circuit is active
the LED blinks orange. It is okay if the limit LED blinks occasionally. If the LED blinks
frequently or lights continuously, turn down the signal level.
SIGNAL LED. The signal indicator lights green if there is signal present on the
main XLR input.
STATUS LED. The status indicator flash if the temperature protection is
active.
POWER LED. This green led is ON when the speaker is connected to the
main power supply and the ON/OFF is in ON position.
MALE XLR SIGNAL OUTPUT. The output XLR connector provides a loop
trough for speakers daisy chaining.
VOLUME CONTROL. Adjust the amplifier volume.
CONTOUR SWITCH. Set the flat or shaped equalization. “Contour” equalization
is a loudness recommended for background music applications, when the
system plays at a low level. For all other applications normal flat equalisation is
recommended.
FLOOR/SIDE SWITCH. Set a specific equalisation for stage monitor position
or in case of two speaker “side to side” (reduction of mid-lows and improvement
of vocal clarity).
NEUTRIK POWERCON AC IN-OUT SOCKET. In-Out AC Powercon Sockets.
POWER MAIN SWITCH. The power switch turns the AC power ON and OFF.
