CAUTION: These servicing instructions are for use by qualified service personnel only. To reduce the risk
of electric shock, do not perform any servicing other than that contained in the operating instructions
unless you are qualified to do so.
Do not install electronic equipment in a confined or built-in space such as a bookcase or similar unit and
keep well ventilated in open space. The ventilation should not be impeded by covering the ventilation
openings with items such as newspaper, tablecloths, curtains etc.

Electronic products :
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 - MOUNTING - Rigging suspending or mounting of speaker systems can expose
members of the public to serious health risks and even death.
UNDER NO CIRCUMSTANCES ATTEMPT TO RIG, SUSPEND OR OTHERWISE MOUNT LOUDSPEAKERS
UNLESS YOU ARE FULLY QUALIFIED AND CERTIFIED TO DO SO BY RELEVANT LOCAL, STATE AND
NATIONAL AUTHORITIES. ALL RELEVANT SAFETY REGULATIONS MUST BE FOLLOWED. IF YOU ARE
NOT PROPERLY QUALIFIED OR DO NOT KNOW OF PERTINENT REGULATIONS, CONSULT QUALIFIED
PERSONNEL FOR ADVICE.
