A Few Suggestions
We recommend that you do not operate your speakers or
subwoofer with the bass,treble and loudness controls set to
full boost.This will place undue strain on your electronics and
speakers and could damage them.
The volume control setting on your processor/preamp or receiver
is not a specific indication of the overall loudness level of the
speakers.The only important consideration is the loudness level at
which the system can be played, regardless of where the volume
control is set.
Always turn down the volume control setting on your processor/
preamp or receiver when changing a cassette or CD, or switching
inputs to AM or FM operation. Excessively loud transients (clicks or
popping sounds) can damage the satellite speakers and possibly
the subwoofer.
Important!
Whenever changing cables, pulling plugs, etc.,ALWAYS TURN OFF
ALL EQUIPMENT, including the subwoofer.
