CERWIN-VEGA! CVI-SERIES

BEFORE YOU BEGIN

The Cerwin-Vega! speakers covered by this manual are designed for portable applications in which the speakers will be
stacked directly on the floor, stage, a solid, stable platform, mounted on a tripod stand or pole-mount. Cerwin-Vega!
Professional does not support suspension of the models covered by this manual nor are these models intended for fixed
installation in outdoor or high moisture environments. Moisture can damage the speaker cone and surround and cause
corrosion of electrical contacts. Avoid exposing the speakers to direct moisture. Keep speakers out of extended or intense
direct sunlight. The driver suspension will prematurely dry out and finished surfaces may be degraded by long-term exposure
to intense ultra-violet (UV) light.

THESE SPEAKERS ARE HEAVY!

Cerwin-Vega! Professional speakers can generate considerable energy. When placed on a slippery surface such as polished
wood or linoleum, the speaker may move due to vibration caused by its acoustical energy output. Precautions should be taken
to assure that the speaker does not fall off a stage or table on which it is placed.

To avoid damage to your speaker and other parts of your system, when you turn on your system, ALWAYS turn on the power
amp last! This will avoid loud, damaging pops that will annoy your audience, and blow your speakers. When you power down,
the amplifier should ALWAYS be turned off first to avoid the same problems.

When using two or more speaker systems, be sure to match the polarity (+/-) of the speaker system connectors to those of the
amplifier. If polarities do not match, the sounds produced by the speaker will interfere with each other, making it impossible to
achieve a well-balanced sound field.

Some Cerwin-Vega! speaker models include a receptacle cup to allow mounting on tripod stands or poles. When using stands,
be sure to observe the following precautions:

• Check the stand specification to be certain it is designed to support the weight of the speaker.

• Observe all safety precautions specified by the stand manufacturer.

• Always verify that the stand is placed on a flat, level, and stable surface and be sure to fully extend the legs of tripod type
stands. Position the stand so that the legs do not present a trip hazard.

• Route cables so that performers, production crew, and audience will not trip over them pulling the speaker over.

• Do not attempt to place more than one speaker on a stand designed for a single speaker.

• Always be cautious in windy, outdoor conditions. It may be necessary to place additional weight (i.e. sandbags) on the base
of the stand to improve stability.

• Unless you are confident that you can handle the weight of the speaker, ask another person to help you get it onto the tripod
stand or pole.

Cerwin-Vega! loudspeakers are easily capable of generating sound pressure levels (SPL) sufficient to cause permanent
hearing damage to performers, production crew and audience members. Caution should be taken to avoid prolonged exposure
to SPL in excess of 90 dB

ANTES DE EMPEZAR

Los altavoces Cerwin-Vega! incluidos en este manual están diseñados para las aplicaciones portátiles en las cuales los
altavoces se apilarán directamente sobre el piso, escenario, o sobre una plataforma sólida y estable, o se montarán sobre un
trípode o columna.

Cerwin-Vega! Professional no recomienda la suspensión de los MODEL'S incluidos en este manual, y estos MODEL'S no están
diseñados para la instalación fija en ambientes exteriores o donde exista un alto nivel de humedad. La humedad puede dañar
el cono del altavoz y el sonido circundante, pudiendo también causar la corrosión de los contactos eléctricos. Evite exponer
los altavoces a la humedad directa. Mantenga los altavoces fuera de la luz solar directa por períodos prologados o a la luz
solar de gran intensidad. La suspensión del excitador se resecará prematuramente y las superficies acabadas pueden
degradarse debido a la exposición a largo plazo a la luz ultravioleta (UV) intensa.

Los altavoces Cerwin-Vega! Professional pueden generar un nivel considerable de energía. Cuando se coloca sobre una
superficie resbalosa, por ejemplo un piso de madera pulida o de linóleo, el altavoz puede moverse debido a la energía
acústica que genera. Se deben tomar precauciones para asegurar que el altavoz no se caiga del escenario o de la mesa en la
cual ha sido colocado.

Para evitar dañar su altavoz y otras partes de su sistema, cuando encienda su sistema, SIEMPRE encienda último el
amplificador de potencia. Esto evitará ruidos fuertes y dañinos que molestarán a su audiencia y dañarán sus altavoces.
Cuando apague el sistema, SIEMPRE deberá apagar primero el amplificador, a fin de evitar los mismos problemas.

Cuando utilice dos o más sistemas de altavoces, tenga cuidado de que cada polaridad (+/-) del conector del sistema de
altavoces coincida con la del amplificador. Si las polaridades no coinciden, los sonidos generados por el altavoz se interferirán
mutuamente, con lo cual será imposible conseguir un campo de sonido bien equilibrado.

Algunos MODEL'S de altavoces Cerwin-Vega! incluyen un receptáculo que permite montarlos en plataformas sobre trípodes
o columnas. Cuando utilice plataformas, tome siempre las siguientes precauciones:

• Consulte las especificaciones de la plataforma para comprobar que esté diseñada para soportar el peso del altavoz.

• Cumpla con todas las precauciones de seguridad especificadas por el fabricante de la plataforma.

• Verifique siempre que la plataforma esté colocada sobre una superficie plana, nivelada y estable, y extienda totalmente las

patas de las plataformas con trípode. Ubique la plataforma en un sitio donde las patas no hagan tropezar a las personas.

• Encamine los cables de modo tal que los músicos, el equipo de producción y el público no se tropiecen con los cables y

arrastren el altavoz.

• No coloque más de un altavoz en una plataforma diseñada para sostener un sólo altavoz.

• Sea cuidadoso cuando haya viento en lugares al aire libre. Puede ser necesario colocar pesos adicionales (por ejemplo,

bolsas de arena) en la base de la plataforma para mejorar su estabilidad.

• A menos que confíe en que puede sostener el peso del altavoz, pida ayuda a otra persona para subirlo a la plataforma de

trípode o columna.
Cerwin-Vega! puede generar fácilmente niveles de presión de sonido (SPL) suficientes para causar daños permanentes al oído

de los músicos, el equipo de producción y el público. Se deben tomar precauciones para evitar la exposición prolongada a
niveles de SPL superiores a 90 dB.

AVANT DE COMMENCER

Les haut-parleurs Cerwin-Vega! décrits dans ce manuel sont conçus pour des utilisations portables au cours desquelles les
haut-parleurs sont empilés directement sur le sol, sur une scène, sur une plate-forme stable et solide, sur un trépied ou sur
un poteau.

Cerwin-Vega! Professional ne recommande pas de suspendre les modèles décrits dans ce manuel ni des les installer à
l’extérieur ou dans des environnements très humides. L’humidité peut endommager le cône du haut-parleur ainsi que le
dispositif d’ambiophonie et provoquer la corrosion des contacts électriques. Éviter d’exposer les haut-parleurs directement à
l’humidité. Éviter leur exposition prolongée ou intense aux rayons du soleil. Une exposition prolongée à des rayons
ultra-violets intenses peut faire sécher prématurément la suspension du circuit d’attaque du haut-parleur et dégrader les
surfaces finies.

Les haut-parleurs Cerwin-Vega! Professional peuvent générer une énergie considérable. Lorsqu’un haut-parleur est placé sur
une surface glissante comme du bois poli ou du linoléum, il peut se déplacer par la force de l’énergie acoustique produite. Des
précautions doivent être prises pour que le haut-parleur ne puisse tomber d’une scène ou d’une table sur laquelle il est placé.

Pour éviter d'endommager votre haut-parleur ou d'autres composants de votre système, vous devez TOUJOURS allumer
l'amplificateur de puissance en dernier! Vous éviterez ainsi les claquements bruyants qui risquent de gêner le public
et d'endommager les haut-parleurs. Lorsque vous arrêtez votre système, éteignez TOUJOURS l'amplificateur de puissance en
premier pour les mêmes raisons.

Lorsque vous utilisez au moins deux systèmes de haut-parleur, n'oubliez pas de faire correspondre la polarité (+/-) des
connecteurs de haut-parleurs à celle des connecteurs d'amplificateur. Si les polarités ne correspondent pas, les ondes
sonores produites par les haut-parleurs entreront en conflit et vous ne pourrez pas obtenir un champ sonore bien équilibré.

Certains modèles de haut-parleurs Cerwin-Vega! sont dotés d’un socle de fixation creux permettant l’installation sur un trépied
ou un poteau. Lors de l’utilisation d’un support, il est important de prendre les précautions suivantes :

• Vérifier, en lisant ses spécifications, que le support puisse supporter le poids du haut-parleur.

• Observer toutes les consignes de sécurité spécifiées par le fabricant du support.

• Il faut toujours placer le support sur une surface plane, nivelée et stable. Ne pas oublier également de bien étirer les jambes

des trépieds. Positionner les jambes du support de façon à ce que personne ne risque de les accrocher.

• Faire passer les câbles de sorte que les interprètes, l’équipe de production et le public ne risquent pas de s’y accrocher et

de faire tomber le haut-parleur.

• Ne jamais essayer de placer plus d’un haut-parleur sur un support conçu pour un seul haut-parleur.

• Une prudence extrême est toujours de mise à l’extérieur, particulièrement lorsqu’il y a du vent. Il pourrait être nécessaire de

lester (notamment avec des sacs de sable) la base du support pour en accroître la stabilité.

• Ne jamais hésiter à demander de l’aide pour installer le haut-parleur sur un trépied ou un poteau, sauf si l’installateur est sûr

de pouvoir en supporter le poids.
Cerwin-Vega! peut facilement générer des niveaux de pression sonore capables de causer des lésions permanentes à l’ouie

des interprètes, des membres de l’équipe de production et du public. Des précautions doivent être prises pour éviter
tl’exposition prolongée de l’ouie à des pressions sonores dépassant 90 dB

SAFETY AND CARE FOR YOUR CVi-SERIES LOUDSPEAKERS

POSITIONING

High and upper mid frequencies are a crucial part of the audio spectrum, and have much to do with how we perceive clarity
and intelligibility. Whereas these frequencies are the most easily located, they are also the first to be acoustically blocked.
Taking the coverage angles of the models used into consideration, be sure to set up your speakers so that the MF and HF
drivers are free from obstructions and the higher frequencies can reach the entire audience (e.g. slightly above the heads of
the audience). This will ensure optimal dispersion of higher frequency content and thus improved speech intelligibility and
clarity.

AVOIDING FEEDBACK

Always place the "front-of-house” speakers (the enclosures facing the audience) in front of the microphones, (e.g. towards the
front edge of the stage). Use professional floor wedges or other dependable monitoring systems to ensure that the performers
on stage can hear themselves. Whenever possible, position monitor speakers so that they point only to the back side of
microphones.

Avoiding Feedback When Using Turntables (e.g. DJ Applications)

Turntables often produce low-end feedback: low frequencies are fed back to the pickup arm and cartridge and reproduced

again by the speakers. Common causes of low-end feedback are speakers positioned too close to the turntable or on wooden
floors or stage elements prone to vibration. To avoid this, position the speakers as far from the turntable as possible. Placing
them on a solid, non-resonating support will also help. If you are using CVi models with pole mount cups, try mounting them
on stands. This will minimize direct contact between floor and speakers and reduce vibration.

PROTECTING YOUR SPEAKERS

Next to following common-sense rules like exercising caution while setting levels to avoid overdriving your power amps, and
understanding and respecting the physical limits of your system, there are a couple reliable methods of protecting your
speakers – and your entire system – using additional equipment.

Using a high pass filter to avoid excessive low frequencies, low-frequency rumble or extreme low frequencies can lead to an
excessive displacement of the speaker diaphragm and in turn to permanent damage. Using an equalizer or a low-cut/high-pass
filter to eliminate the low frequencies below the response curve of the speaker can effectively prevent this.

Most consoles and outboard equalizers, as well as many other outboard signal processors (and of course speaker
management systems) provide a high pass filter. The use of a high pass filter in the signal path is especially recommended
when using turntables and/or CD players as signal sources. CD players often produce extremely low frequencies, which can
lead to excessive diaphragm displacement.

Using a limiter to limit the output level, insert the limiter between the mixing console output and your power amp. Many types
of outboard signal processors and most speaker management systems include limiters for this application. Used properly, they
can eliminate overdriving of your audio signals and effectively suppress dangerous signal peaks, which can not only degrade
the sound quality, but also cause permanent damage to your speakers and other system components.

POWER AMPLIFIER SELECTION

Choosing the right power amplifier has a major effect on the performance of your speakers. The amplifier should always
provide at least as much power as the speaker system is capable of handling. In order to ensure precise reproduction of brief,
high-power transients, the amp should provide about twice as much power as the speakers can handle. The minimum
recommended input power ratings for all CVi Series speakers are displayed in the Specifications Table.

CABLE SELECTION

The quality and characteristics of the speaker cables used also greatly affect speaker performance. Always use high-quality
cables made with professional-grade wire and connectors that are correctly and carefully fitted. Selection of the appropriate
wire gauge is especially important to system operation. A cable that is too light or low-gauge will result in amplifier power being
wasted due to the series resistance of the cable and in loss of low-frequency performance due to degraded damping factor.
The ideal gauge is determined by a few factors: the length of the cable, the load or impedance, and the amount of power
supplied to the speakers. For cable runs up to 50 feet (15m) with an 8-Ohm load, we recommend using at least 14-gauge wire
– 12-gauge is minimum for a 4-Ohm load. For runs between 50 and 100 feet (15-30m), use at least 12-gauge for 8-Ohm loads
and 10-gauge for 4 Ohms. At 200 feet (60m), you should use 10-gauge and 8-gauge, respectively, and so on.

MOISTURE

Moisture can damage the speaker cone and surround and cause corrosion of electrical contacts. Avoid exposing the speakers
to direct moisture. Keep speakers out of extended or intense direct sunlight. The driver suspension will prematurely dry out
and finished surfaces may be degraded by long-term exposure to intense ultra-violet (UV) light.

POWERING UP

To avoid damage to your speaker and other parts of your system, when you turn on your system, always turn on the power
amp last! This will avoid loud, damaging pops that will annoy your audience, and blow your speakers. When you power down,
the amplifier should always be turned off first to avoid the same problems.

POLARITY

When using two or more speaker systems, be sure to match the polarity (+/-) of the speaker system connectors to those of the
amplifier. If polarities do not match, the sounds produced by the speaker will interfere with each other, making it impossible to
achieve a well-balanced sound field.

HIGH FREQUENCY FAST REACTION PROTECTION CIRCUIT

Your CVi Series speakers offer a fast reacting suppression limiter that senses input voltage and reduces potentially damaging
voltage levels that would otherwise reach your high frequency drivers.
