UNPACKING
Check your subwoofer carefully. If it has been damaged in
transit, report the damage immediately by calling your dealer
and/or the trucking firm that delivered it.
To prevent fire or shock hazard, DO NOT EXPOSE
THIS SUBWOOFER SYSTEM TO RAIN OR EXCESSIVE
MOISTURE. To avoid electrical shock, DO NOT OPEN
THE SUBWOOFER! There are no user serviceable parts
inside. Observe all warnings and cautions.
A FEW SUGGESTIONS
We recommend that you 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 preamplifier or stereo
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
preamplifier or stereo 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.
Whenever changing cables, pulling plugs, etc., ALWAYS
TURN OFF ALL EQUIPMENT including the Subwoofer.
This prevents transients from entering the speakers and
prevents electrical energy from reaching you. Keep all
connections out of the reach of children.
ABOUTTHIS PRODUCT
The Infinity BU-2 Powered Subwoofer has been designed to
enhance the bass frequencies of any audio system. This
subwoofer may be used with speakers of any size. Obviously,
the greatest bass enhancement will be achieved when the
subwoofer is connected with speakers which do not have the
capability to create deep bass. This subwoofer may be used
individually, or combined with another BU-2 for even more
impressive reproduction of bass frequencies (i.e., one subwoofer
near the satellite speakers and a second subwoofer behind the
primary listening area or both subwoofers up front).
The BU-2 is a self-powered system utilizing a solid state,
low frequency monophonic amplifier driving a specially
designed woofer mounted within a structurally rigid, tuned
port enclosure.
