CERWIN-VEGA! PROFESSIONAL ACTIVE SERIES
BEFORE YOU BEGIN
The Cerwin-Vega! active speakers covered by this manual are designed for portable applications in which the speakers will
be stacked directly on the fl oor, 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 fi xed 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 fi nished surfaces may be degraded by long-term exposure to intense ultra-violet (UV)
light.

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

tions:
• Check the speaker pole shaft specifi cation to be certain it is designed to support the weight of the speakers.
• Observe all safety precautions specifi ed by the speaker pole shaft manufacturer.
• Always verify that the subwoofer is placed on a fl at, level, and stable surface
• Route cables so that performers, production crew, and audience will not trip over them, toppling the speaker.
• Always be cautious in windy, outdoor conditions as the stability of the entire system may be compromised.
Cerwin-Vega! active speakers are easily capable of generating sound pressure levels (SPL) suffi cient to cause permanent hear-
ing damage to performers, production crew and audience members. Caution should be taken to avoid prolonged exposure
to SPL in excess of 90 dB.
