WARNING
When the Unit is in Use
• Turn down the amplifier before switching 
on the amplifier. If there is no sound, 
check the speaker connections. Speakon 
connectors must be locked in place.
• Should any of the following irregularities 
be found during use, immediately switch 
off the amplifier power, disconnect the 
power supply plug from the AC outlet and 
contact your nearest Quest dealer:
• If you detect smoke or a strange smell 
coming from the unit,
• If the unit falls and the unit case is 
damaged,
• If it is malfunctioning (no HF or low 
frequency output).
Make no further attempt to operate the unit if 
it is found to be in any of the above conditions 
as this may cause fire or electric shock.
When Installing the Unit
• Do not expose the unit to rain or an 
environment where it may be exposed to 
water or other liquids, as doing so may 
result in damage to the bass driver or 
corrosion of the steel protective grill.
• Do not cut, kink, otherwise damage 
nor modify the speaker cable. Also use 
speaker cable of at least 1.5mm core 
diameter. In addition, avoid locating the 
speaker cables close to heaters, high 
traffic areas or locations where the cables 
can be damaged.
• Avoid installing or mounting speaker 
boxes in unstable locations and when 
flying, use the hardware designed for the 
speaker box and fix securely to a solid 
wall. Failing to do so may result in the 
unit falling, causing personal injury and/or 
property damage.
• Be sure to ground to the safety ground 
(earth) terminal to avoid electric shock. 
Never ground to a gas pipe as a 
catastrophic disaster may result.
• Never hang a speaker box from only 
one rigging point. Use multiple points 
and attach a safety line to a point strong 
enough to take the weight of the speaker 
box.
WARNING
Flying the box from one insert must not be attempted! 
Improper installation may result in damage, injury or death.
