IMPORTANT WARNINGS & SAFETY INSTRUCTIONS
1
1. READ ALL INSTRUCTIONS – Carefully and become familiar with the features and functions of these products before operating
them.
2. RETAIN THESE INSTRUCTIONS – For future reference.
3. COMPLY WITH ALL WARNINGS – Non compliance may void warranty of the product.
4. USE WITH AMPLIFIERS – In order to avoid damage to drivers and other equipment, it is advisable to establish and follow a
routine for powering up and powering down a sound system. With all system components connected, turn on source equipment
(mixers, signal processors, record 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 few 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.
5. CABLES – Do not use shielded or microphone cables for connection between amplifiers and speakers. Use only approved
speaker cables with proper connectors.

regulations must be followed. If you are not properly qualified or do not know of pertinent regulations, consult qualified personnel
for advice.
7. CAUTION – These professional loudspeaker systems are capable of generating 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.
