Safety precautions
YOU ART. WE SOUND.
Potential risk of personal injury
Never stand in the direct sound beam close to a loudspeakers driven at a high level.
Professional loudspeaker systems can cause sound pressure levels that could harm
human health. Noncritical sound levels at about 90 dB can cause hearing damage if
people are exposed to it over a longer period.
In order to prevent accidents when deploying loudspeakers on the ground or when
own, please take note of the following:
• When setting up the loudspeakers or loudspeaker stands, make sure they are
standing on a rm surface. If you place several systems on top of one another, use
straps to secure them against movement.
• Only use accessories which have been tested and approved by Cadenbach Acous-
tics for assembly and mobile applications. Pay attention to the correct application
and maximum load capacity of the accessories.
• Ensure that all additional hardware, xings and fasteners used for installation or
mobile use are of an appropriate size and load safety factor. Pay attention to the
manufacturers instructions and to the relevant safety guidelines.
• Regularly check the loudspeaker housings and accessories for visible signs of
wear and tear, and replace them when necessary.
• Regularly check all load bearing bolts in the mounting devices.
Potential risk of material damage
Loudspeakers produce a static magnetic eld even if they are not connected or not
in use. Therefore make sure when erecting and transporting loudspeakers that they
are not near equipment and objects which may be impaired or damaged by an ex-
ternal magnetic eld.
WARNINGS ON THE SPEAKERS BACK PLATE:
THIS EQUIPMENT CAN GENERATE EXTREME SOUND PRESSURE LEVELS THAT CAN LEAD TO
PERMANENT HEARING DAMAGE.
THIS SURFACE MAY REACH HIGH TEMPERATURES WHILE IN USE.
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK DO NOT EXPOSE THIS EQUIPMENT TO
RAIN OR MOISTURE.
NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL.
ONLY PERSONAL CERTIFIED TO BE TRAINED BY CADENBACH ACOUSTICS, HAVING PASSED
S1 COURSE SHOULD SETUP THIS SYSTEM, OTHERWISE ANY WARRANTY IS VOID. SEE COR-
RESPONDING MANUAL.

MINERVA 10 inch FIR point source loudspeaker
Product description
YOU ART. WE SOUND.
Overview
MINERVA is a point source loudspeaker with rotatable and interchange able Horn in a trap-
ezoid design. MINERVA offers four 8 mm inserts for mounting. Even full active equipped
MINERVA is still light wight and offers in all version more than 133 dB SPL at 1 meter. This
enables the system to be used as main Loudspeaker system either as single speaker or in
multiple horizontal and also vertical speaker array arrangement.
MINERVA was designed for wide range natural sound reproduction, whether using the speak-
er vertically or horizontally the Mid to High frequency 65° by 40° (95° x 55° when ordering
MINERVA9) CD horn delivers constant directivity and dispersion control and can be rotated
into either the horizontal or vertical plane.
The construction of the 10 inch Low frequency neodymium cone with it’s 2.5 inch voice coil
and Mid To High 1.5 inch exit driver section offers phase coherence between both chassis
around crossover point of more than 4 octaves, creating a remarkable point source behav-
iour. The ring radiator design of the Mid to High compression driver has got a 1.75 inch voice
coil delivering extra high excursion possibilities and radiates distortion free sound also above
16 kHz.
TEUTATES is the dedicated low frequency extension, anyway all cadenbach acoustic sub
woofers can be chosen to run with MINERVA.
On order MINERVA incorporates a very power full frequency modulated oating modulator
amplier. Due to it’s advanced high efciency power technology it runs at any moment at
very low temperature and needs no fan cooling at all.
Operation
The frequency and phase response of MINERVA is exceptional smooth at very low THD.
MAGNA can run passive but needs some frequency correction of a controller and it can run in
linear phase mode by using Cadenbach Acoustics FIR lter of the HEIMDALL D1 digital con-
troller. It’s rotatable and interchange able horn offers full CD dispersion control in horizontal
and vertical point source mode.
Applications
• Small concert halls, theatres and houses of worship, AV applications.
• Small to medium main system sound reinforcement.
• Side or front ll system, under balcony or distributed system.
Features
• Trapezoid design with wide range output, with optional integrated amplier
• Optimal integration with TEUTATES sub woofer.
• Very exible CD coverage via rotatable, replace able Horn and Cadenbach Acoustics FIR lters.
• Four 6 mm inserts for various own congurations

Protecting your speaker
MINERVA 10 inch FIR point source loudspeaker
MINERVA speakers may be used in combination with Cadenbach Acoustics
PAX Ampliers and Cadenbach Acoustics HEIMDALL controller.
In general, audio signals must not be over driven. This may be caused by
mixing consoles, equalizers, effect equipment, etc. and should be indi-
cated on this equipment. When a power amplier is over- loaded at the
output (clipping), then the amplier activates a clipping warning signal.
In any case, the signal must be reduced as soon as it sounds unnaturally
distorted.
Damage caused by overloading the speakers or using the speakers with-
out Cadenbach Acoustics PAX and HEIMDALL we do not assume warranty
and excludes liability for possible consequential damage.
Permanent high-level signals with high frequency and continuous noise
from feedback or permanently distorted high-level signals or noises,
which occur when the amplier is on while equipment is being connected,
disconnected or switched on could damage the loudspeakers.
Do not install loudspeakers at places where they are permanently ex-
posed to direct sunlight, high moisture, direct rain or strong vibrations
and dust.
