ACCESSORIES

 – Only use accessories which are designed for professional use or recommended by the

manufacturer. If a cart, rack or tripod stand etc is used in conjunction with this product, care must be taken to

avoid tip-over or fall risk.

POWER ON WORKFLOW 

– 

To avoid damage to drivers and other equipment, it is advisa ble to establish 

and follow a workflow for powering up and powering down a sound system. With all system components 

connected, turn on source equipment (mixers, signal processors, recording and playback units, etc.) BEFORE 

powering up amplifiers. Transient voltages from powering up source equipment can damage speakers if 

amplifiers are already turned on. Make sure that amplifier volumes are set to their minimum settings and 

power up any system amplifiers LAST. It is recommended that all system components be allowed to stabilize 

for several seconds before any source signals are introduced or level setting adjustments are made. 

Similarly, when shutting systems down, turn all amplifiers off first, before powering down any other system 

components.

CABLING

 - 

Do not use shielded or microphone cables for connection betw een amplifiers and speakers. 

Use only approved speaker cables with proper connectors. Do not defeat any grounding-type (Earthed) 

plugs on electronic products.

CAUTION

 - 

Professional loudspeaker systems can generate very high sound pressure levels. Use care with

placement and operation to avoid exposure to excessive volume levels. Permanent hearing damage can 

result when operated to extreme levels.

 - 

Rigging suspending or mounting of speaker systems can expose

members of the public to serious health risks and even death.
