Passive speaker user guide

INTRODUCTION
Thank you for buying a Carlsbro product. Correctly used it will provide
years of reliable service, and fulfil all your performance needs. Please
read this user guide thoroughly in order to safeguard your equipment,
and obtain maximum performance from it.
Unpacking and inspection
Carefully unpack the unit. If it appears
damaged in any way, return it to the
dealer it was purchased from in its
original packaging. Carlsbro
Electronics Ltd cannot accept any
responsibility for damage arising from
the use of non-approved packaging.
WARNING IMPORTANT SAFETY INSTRUCTIONS~
Loudspeaker cabinets are often heavier than they look, so always
take care when lifting or moving them. Some cabinets may require
two or more people to move them safely. Always carry the speakers
by their carrying handles (where fitted)

Do not stand close to loudspeakers at high volumes, as
permanent hearing damage may occur. Restrict your exposure to
high sound pressure levels and use suitable hearing protection for
prolonged exposure.
When setting up a PA system make sure that the surface used is
level and can support the weight of the system. If speaker
cabinets are to be stacked, use straps to secure them against any
movement. Always keep speakers as far from the public as
possible to prevent injury. Use only approved stands and brackets
to support loudspeakers.

Never place any liquid filed vessels on or near the
loudspeaker, and ensure that the unit is not exposed
to moisture in any way.
Only suspend the speakers if the speaker cabinet
has approved flying hardware fitted to it. Under no
circumstances should the speakers be suspended
in any other way.
Loudspeakers create a permanent magnetic
field around them. Keep magnetically sensitive
objects away. (Examples are bank cards, floppy
discs, televisions, audio and video tapes, etc).
