IMPORTANT SAFETY INSTRUCTIONS

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 - All warnings and instructions for this product should be adhered to.

3. RIGGING - SUSPENDING - MOUNTING - Rigging suspending or mounting of speaker systems can expose members of

the public to serious health risks and even death.

7. SERVICE - There are no user serviceable parts inside this product. Users should not attempt to service this product.

Warranty nulliﬁcation could result if this is attempted.

6. CAUTION - 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.

5. CABLES - Do not use shielded or microphone cables for connection between ampliﬁers and speakers. Use only approved

speaker cables with proper connectors.

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 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.

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.
