System Description:
The i10NCX systems is a compact coaxial 2-way point sources with passive
frequency dividing network in a ported cabinet made of waterproof glued
plywood with fine textured paint finish. The systems provides a coverage of 80°
radial. The system is protected by a robust protective grill with foam overlay. Two
integrated handles are provided for an easier handling. The i10NCX system is
primarily intended for fixed installation with shorter (critical) listening distance
but can be ordered with PU coating for mobile use. In stand-alone or spaced
array operation, it can be used as a main, support or effect speaker. Due to its
neutral reproduction characteristics and the high maximum SPL Level, it is
equally suitable for speech and music transmission. For low end support, the DAL
Sub-Low systems, BR12N, BR15N, BR115 and BR118 are suitable.
Featuring an 1,3” Hi driver with 2,5” (65mm) Voice coils coaxial loaded by an
efficient 10"cone driver with 2.5" (65mm) voice coil the i10NCX system provides
an audio bandwidth of 60Hz - 18KHz with a Peak power handling of 500W.
The i10NCX systems can be operated without the DAL Control & Drive Systems.
It's passive frequency deviding network features an integrated (RMS) protection
limiter for the high frequency driver. When operated with the DAL Control & Drive
System, the system is optimal parameterized for sonic quality and protected for
maximum continuous and peak sound pressure level. The DAL Control & Drive
Systems provides different settings for the operation of i10NCX combinations.
The i10NCX offers a dispersion pattern for stand-alone operation.

Safety and operational reliability
Observe the following safety instructions when operating loudspeakers to avoid
risks. The i10NCX loudspeaker has been developed exclusively for professional
use in sound reinforcement systems. The loudspeaker may only be used by
instructed and qualified personnel. Observe the operating modes described in
these operating instructions. Other uses are not permitted.
The i10N can be operated without the DAL Control & Drive electronics, but then it
the performance data may differ.
In operation avoid Feedback, distorted signals (clipping), peaks resulting from
plugging or unplugging devices in the signal chain, long term pure sine wave
tones with high power and too weak power amplifiers not specified by their
power ratings. Such signals and devices can cause loudspeaker overload or
damages and are not covered by our warranty.

Safety instructions:
Warning
Loudspeakers have a permanent magnetic field. Persons with pacemakers must
not be in the immediate vicinity of loudspeakers, as magnetic fields can lead to
interference with pacemakers. When repairing loudspeakers, it must be ruled out
that the magnetic components come into contact with persons wearing
pacemakers.
Warning
Loudspeakers have a permanent magnetic field. This can interfere with the
operation of other components in the immediate vicinity that are magnetically
sensitive.
Beware
The i10NCX is suitable for flown operation and offers mounting points for
this purpose. For flown operation, the original Manufacturer hardware must
be used and a proven static of the hanging point is mandatory. When
installing and commissioning in standing or stacked operation, pay careful
attention to secure footing and solid professional mounting. In stacked
operation, the loudspeakers must be secured as a group against slipping or
falling over, e. g. with suitable tension straps on stages. A falling
loudspeaker can cause great damage to property and personal injury. Use
only material specified by DAL for the installation and mounting of DAL
loudspeakers. This work must be carried out by qualified personnel.
Observe the applicable safety regulations when doing so.
Caution
Do not stand in the immediate vicinity of loudspeaker systems that are operated
at high sound pressure levels. Wear hearing protection when testing and setting
up speaker systems. These speaker systems - operated at high sound pressure
levels - can endanger health. Even seemingly low sound pressure levels of
90dB/SPL can cause long-term impairment or damage to hearing.
Attention
When setting up, storing and transporting loudspeakers, ensure that excessive
environmental influences such as direct sunlight, moisture, vibrations and dust
have no effect. When operating the loudspeakers, avoid feedback, distorted
signal transmission and playback as well as signal peaks that can be caused by
switching devices in the signal chain on and offor disconnecting them from the
signal chain during operation. Make sure that the loudspeaker is not exposed to
permanent thermal overloads, which may cause fire and result in damage to
property and personal injury. DAL will not be liable for any damage caused in this
way and will not accept any warranty or liability for consequential damage.

Technical Notes
Safety steels may be used only with the M10 threaded inserts. M6 or M8 threaded
inserts in the rear are to be used exclusively with DAL original accessories or are
designed as lashing points. A"er use, make sure that the countersunk screws
belonging to the cabinet are screwed back into the threaded sleeves in order to
maintain an air-tight system.
DAL protective grilles with foam lamination are the mechanical protection
component for the built-in transducers and offer a high acoustic transmission as
well as their affixing minimizes sonic influences of the grilles. The backing or
covering of the grilles with foam serves also as UV-light protection, dust
protection and improves the optical unobtrusive of the systems. Only
undamaged grilles and foams can fulfill these tasks. Replace warped grilles or
worn foams to maintain their function.
DAL loudspeaker systems with polyurea-coated or painted enclosures are
basically suitable for temporary outdoor operation, even in the rain.
For indefinite operation outdoors as in fixed installations, the loudspeaker
systems must be protected with a hood against direct sunlight and rain. If
necessary, the loudspeaker should be equipped with the optional front grille with
weather protection.

Most DAL loudspeaker systems can be supplied for extra charge from the factory
in a weatherproof (WR) or sea-weatherproof (SWR) variant.
For indefinite operation outdoors in subtropical and tropical areas, the
loudspeaker should be ordered as the WR variant. For indefinite operation at sea
and other areas with a humid and salty atmosphere, the loudspeaker should be
ordered in the SWR equipment variant. Both variants are manufactured at the
factory only.
The i10NCX is designed for standing or flown operation. When setting up,
suspending and positioning the system, make sure it is on a firm and leveled
surface and that the selected load points have a proven load-bearing capacity.
Use approved stands and approved mounting accessories that are designed for
the weight load. Additionally secure the ground stacked or flown speaker system
before commissioning to prevent personal injury and property damage.

Test And Maintenance
The wiring of the loudspeaker components inside the cabinet is according to the
diagram to the le". With an impulse phase checker, which delivers a signal with
non-inverted phase, a signal of positive polarity is obtained directly measured in
front of the cone transducer. If the same test is performed in front of the high
frequency driver/horn, a signal with positive polarity is obtained.
If the diaphragm of the high-frequency driver is replaced, make sure that the
original spacer ring (if originally fit) made of a thin plastic material remains in the
driver so that the new voice coil is correctly positioned in the magnetic field.
Transducers and horn need to fit back airtight in the cabinet a"er a service.
It is good practice to check loudspeaker systems frequently in concern of
mechanical integrity and distortion free sound reproduction.
Here is a simple way to quickly check sound reproduction. Use a sine wave
generator with sweep function or a tunable sine wave generator and a power
amplifier. Adjust the test system to deliver an appropriate sound power level and
tune the sine wave generator from low to high frequencies. Listen to the acoustic
output the loudspeaker delivers. The signals should be free of audible
distortions. Mechanical noise from the system or unwanted reproduction of side
tones should be followed up by inspection and search for the root cause.
Fixing and mounting points should be inspected frequently.
