IMPORTANT SAFETY INSTRUCTIONS
1. Read these instrucons.
2. Keep these instrucons.
3. Heed all warnings.
4. Follow all instrucons.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any venlaon openings. Install in accordance with the manufacturer’s instrucons.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including ampliers) that
produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than
the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided
for your safety. If the provided plug does not t into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched, parcularly at plugs, convenience receptacles, and the point where
they exit from the apparatus.
11. Only use aachments/accessories specied by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specied by the manufacturer, or sold with the apparatus. When a cart
is used, use cauon when moving the cart/apparatus combinaon to avoid injury from p-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of me.
14. Refer all servicing to qualied service personnel. Servicing is required when the apparatus has been damaged in any way, such
as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate normally, or has been dropped.
15. Warning: to reduce the risk of re or electric shock, do not expose this apparatus to rain or moisture.
16. Do not expose this equipment to dripping or splashing and ensure that no objects lled with liquids, such as vases, are placed
on the equipment.
17. To completely disconnect this apparatus from the ac mains, disconnect the power supply cord plug from the ac receptacle.
18. The mains plug of the power supply cord shall remain readily operable.
19. This apparatus contains potenally lethal voltages. To prevent electric shock or hazard, do not remove the chassis, input
module or ac input covers. No user serviceable parts inside. Refer servicing to qualied service personnel.
20. The loudspeakers covered by this manual are not intended for high moisture outdoor environments. Moisture can damage
the speaker cone and surround and cause corrosion of electrical contacts and metal parts. Avoid exposing the speakers to
direct moisture.
21. Keep loudspeakers out of extended or intense direct sunlight. The driver suspension will prematurely dry out and nished
surfaces may be degraded by long-term exposure to intense ultra-violet (UV) light.
22. The loudspeakers can generate considerable energy. When placed on a slippery surface such as polished wood or linoleum,
the speaker may move due to its acouscal energy output.

INTRODUCTION
The CXL12A is a coaxial stage monitor designed specically for live sound, although the very compact, low-prole enclosure also
makes it suitable for theatre and television applicaons. The combinaon of a high-performance coaxial transducer, a carefully
designed cabinet, and powerful electronics provides very high SPL before feedback and excellent intelligibility even at very high
power.
The transducer’s coaxial design oers a very stable acouscal paern in both the horizontal and vercal axes. The very compact,
single magnet neodymium motor reduces the delay between the two sources, eliminang me and phase problems, and guarantees
high performance with a consistent weight reducon.
The high frequency range is reproduced by a low-distoron compression driver equipped with a 1.7” aluminium voice coil and
polyimide diaphragm. The custom designed horn provides a precise and controlled dispersion of 50° horizontal and 70° vercal,
allowing an excellent performance at close listening distance and, at the same me, a consistent o-axis coverage.
The 12” woofer employed in the reproducon of the low frequency range is equipped with a 2.5” voice coil. Thanks to a special
treatment process that makes the cone water repellent, the CXL12A is able to perform in adverse weather condions and is therefore
suitable for outdoor use.
The reduced size of the Balc birch cabinet makes the CXL12A a very compact and lightweight stage monitors and makes it suitable
for all applicaons where unobtrusive size is a must. The handles on both sides of the cabinet make it very easy to transport the
monitor and to posion it on stage. A convenient dual-angle pole holder allows the CXL12A to be mounted on a standard speaker
stand to be used as a mulpurpose front of house loudspeaker.
The system processing is based on the CORE LT DSP plaorm designed by the PROEL R&D Laboratories, featuring high-performance
signal processing and high-denion 24bit converters, capable to deliver an outstanding sound denion and dynamic performance.
The CXL12A is powered by a DA Series Class D power amplier with SMPS. The innovave technology used for these ampliers oers
top-of-the-range performance, such as superior sound denion atany audio frequency, very high dynamics even for low level
signals and very low distoron even at maximum power.

I/O AND CONTROL OPERATIONS
MAINS IN - Powercon® NAC3FCA power input connector (blue). To switch the amplier on, insert the Powercon® connector and turn
it clockwise into the ON posion. To switch the amplier o, pull back the switch on the connector and turn it counter-clockwise
into the POWER OFF posion.
WARNING: In the case of product failure or fuse replacement, disconnect the unit completely from the mains power.
The power cable must only be connected to a socket corresponding to the specicaons indicated on the amplier unit.
The power supply must be protected by a suitably rated thermo-magnec breaker. Preferably use a suitable switch to
power on the whole audio system leaving the Powercon® always connected to each speaker, this simple trick extend
the life of the Powercon® connectors.
MAINS OUT - Powercon® NAC3FCB power output connector (grey). This is connected in parallel with the MAINS ~ / IN. The maximum
load applicable depends on the mains voltage. With 230V~ we suggest to link a maximum of 4 CXL12A loudspeakers, with 120V~
we suggest to link a maximum of 2 CXL12A loudspeaker.
INPUT - Audio signal input with locking XLR connector. It has a fully electronically balanced circuitry including AD conversion for the
best S/N rao and input headroom.
LINK - A direct connecon from the input connector to link other speakers with same audio signal.
SIGN/LIMIT - This LED lights in green to indicate the presence of the signal and lights in red when an internal limiter reduces the
input level.

PRESET BUTTON - Pressing it you can select the DSP PRESET. The selected PRESET is indicated by the corresponding LED:
NORMAL WEDGE This PRESET is suitable for typical stage monitor applicaons.
COUPLED UNITS This preset provides the correct EQ when two CXL12A monitors, fed with the same audio signal, are placed
at no more than 0,6 m (2 feet) one to the other. To be used for double stage monitoring for singers or other
musicians.
LOW CUT This PRESET is the same as NORMAL WEDGE but with a low cut at 110 Hz 48 dB/oct. To be selected when a
CXL12A is used in combinaon with a subwoofer to form a DRUM FILL or a SIDE FILL system. It can be used
also in case you need to cut drascally the monitor LF response.
FOH This preset provides the correct response when the CXL12A is used as main system on a pole.
FOH LOW CUT This PRESET is the same as FOH but with a low cut at 110 Hz 48 dB/oct. To be selected when a CXL12A is
used in combinaon with a subwoofer to form a main system or as FRONT FILL system. It can be used also
in case you need to cut drascally the LF response.
