CERWIN-VEGA! PROFESSIONAL ACTIVE SERIES

BEFORE YOU BEGIN

The Cerwin-Vega! subwoofers 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! does not support suspension of the subwoofer 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.

Cerwin-Vega! subwoofers can generate considerable energy. When placed on a slippery surface such as polished wood or linoleum, the speaker may move due to 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.

Some Cerwin-Vega! subwoofers include a receptacle cup to allow mounting of a satellite speaker on top of the subwoofer using a standard speaker pole shaft. When using a standard speaker pole shaft, be sure to observe the following precautions:

oCheck the speaker pole shaft for specification to be certain it is designed to support the weight of the speaker. o Observe all safety precautions specified by the speaker pole shaft manufacturer.

o Always verify that the subwoofer is placed on a flat, level, and stable surface

o Route cables so that performers, production crew, and audience will not trip over them, toppling the speaker. o Always be cautious in windy, outdoor conditions as the stability of the entire system may be compromised.

Cerwin-Vega! subwoofers 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.
