INTRODUCTION

The Infinity BU-1 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 that do not have the capability to create deep bass. This subwoofer may be used individually, or combined with another BU-1 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-1 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.

UNPACKING THE SUBWOOFER

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 electric 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.
