CARE AND MAINTENANCE Your speakers are designed to work with a wide range of electronic components. As little as 20 watts per channel can provide enough power for most applications. If you have a large room or prefer louder listening levels, more power may be required. Caution: When choosing an amplifier, do not exceed the power rating of the speaker. If you hear very high levels of audible distortion you are exceeding the capabilities of the system.

OPERATION After you have connected your subwoofer, adjusted it for proper operation with the rest of your system, and experimented to find the best location for it, it’s time to sit back and enjoy it. As you do, here are some hints for getting the most out of your subwoofer. A) The subwoofer’s level control is designed to adjust the balance between your subwoofer and main stereo speakers and should not be used as a substitute for the bass or loudness controls on your amplifier or receiver.
CONGRATULATIONS... SET-UP AND ADJUSTMENT ... on your purchase of a DCM powered home subwoofer system. Your new subwoofer is one of the most exciting home entertainment electronic products available, adding impact and realism to recorded music and the wide variety of movies to be found on videotape, laser disc, DVD and off-the-air broadcasts.
B) For use with A/V preamps and receivers that have 5.1 channel line level outputs. If your preamplifier or receiver has a single “subwoofer” output or “LFE” output, connect a shielded cable from the preamplifier output to either one of the subwoofer line level inputs. Refer to Figure E. UNPACKAGING/PRE-INSTALLATION INSTRUCTIONS Unpack your new subwoofer carefully, keeping the carton and packing material for future use.
EXPLANATION OF FEATURES AND CONTROLS Installation using line level inputs Refer to figure A. A) Using a preamp or receiver with line level outputs. If a preamplifier output is available on your receiver, or you have a preamplifier, connect it to the stereo line level RCA type input jacks on your subwoofer. Use quality shielded cables and connectors. Connect one set of shielded cables from the preamplifier output to the subwoofer input.
B) For amplifiers with two sets of speaker connections. An alternate method of connecting your subwoofer and main speakers is possible if you have a receiver or amplifier that can accommodate two sets of speakers that can be switched on at the same time and be connected in parallel. (Note that some receivers and amplifiers connect “A” and “B” sets of speakers in series, not parallel. A series wiring will not allow this alternate connection method for your subwoofer.
PLACEMENT OR POSITIONING WIRING AND CONNECTIONS Your new subwoofer will work well in a variety of locations. However, placement in your listening room will affect its performance. Since the wavelengths of sound reproduced by your subwoofer are large compared to its size, those sounds are omni-directional in nature. This means that locating your subwoofer in relation to your left and right main speakers will not affect the directional cues which they provide.
