BEFORE YOU BEGIN
Cerwin-Vega! CVi-SerieS
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
