OPERATION Power On Crossover Adjustments Plug your subwoofer’s AC cord into a wall outlet. Do not use the outlets on the back of the receiver. Note: This control will have no effect if the Normal/LFE Switch 5 is set to “LFE.” If you have a Dolby Digital or DTS processor/receiver, the Crossover Frequency is set by the processor/receiver. Consult your owner’s manual to learn how to view or change this setting. Initially set the Subwoofer Level (Volume) Control 8 to the “min” position.
BASS OPTIMIZATION SYSTEM™ Infinity’s Bass Optimization System is a simple-to-use, yet sophisticated, low-frequency calibration system.The Beta SW-12 contains a parametric equalizer that you can adjust following the directions below. By following these instructions, you can improve the sound of your system. The Bass Optimization System Goal It is a fact of audio that what we hear at low frequencies is determined as much or more by the listening room than by the loudspeaker itself.
MAINTENANCE AND SERVICE The enclosure and grille may be cleaned using a soft cloth to remove fingerprints or to wipe off dust. All wiring connections should be inspected and cleaned or remade periodically.The frequency of maintenance depends on the metals involved in the connections, atmospheric conditions, and other factors, but once per year is the minimum. If a problem occurs, make sure that all connections are properly made and clean.
