USING YOUR SUBWOOFER WITH HIGH-SENSITIVITY SPEAKERS When the subwoofer is used with high-sensitivity speakers more volume gain may be required. You can obtain 6 dB more gain by using a "Y" cable and plugging into both input jacks (not shown). FINE TUNING Once you have the rest of your speakers positioned in the room and have set speaker distances and calibrated speaker levels with your Processor or A/V Receiver, it's time for a little fine tuning of the subwoofer(s). Subwoofer Controls When setting the subwoofer controls use music and video soundtracks that you know well. They should contain selections with extended bass that is continuous and repetitive. When you are adjusting your subwoofer, remember: Bass should not be overbearing-the subwoofer should not draw attention to itself-but sound shouldn't be "thin" or difficult to hear. Certain subwoofer placement may result in bass frequency cancellations-this occurs when your front speakers and subwoofer are "out-of-phase", in other words, they work against each other through the crossover region. This will result in bass being reduced. If bass sounds weak or dislocated adjust the phase according to the instructions that apply to your subwoofer in the setup procedures that follow. NOTE: When using receivers with Automatic Level and Crossover setting systems such as the Anthem Room Correction, refer to your receiver's Owners Manual for correct setup procedure, otherwise follow the instructions below. SETTING SUBWOOFER CONTROLS Set tone or equalizer controls on your receiver or preamplifier to flat (or 0°) and switch any loudness controls off. 1. Turn the Subwoofer Level control completely counterclockwise to its minimum; 2. Turn the Subwoofer Cut-Off Frequency control clockwise to its highest frequency (i.e. 150 Hz). 3. Set the Phase Alignment Control to 0°; 4. While you listen to a bass music or video selection in your primary listening area, have an assistant turn up the Subwoofer Level control until the subwoofer can be clearly heard; 5. Have an assistant try the Phase Alignment control until you hear the most bass. Your subwoofer and front speakers are now in phase. Do not change phase alignment again unless you move the subwoofer or the front speakers to a different location in the room or move or remove large items of furniture or room furnishings (i.e. carpet, draperies, etc.) 7. Turn the Subwoofer Cut-Off Frequency control completely counter-clockwise to its lowest frequency (i.e. 50 Hz); 8. Slowly rotate the Subwoofer Level control until you match the subwoofer output level with the level of your front speakers. Bass should be clearly audible, but not intrusive; NOTE: If using an A/V receiver or processor to control crossover setting, skip the next step and set the subwoofer cut-ff frequency control to 'Bypass.' 9. Slowly rotate the Subwoofer Cut-Off Frequency control until you hear the best subwoofer/main speaker blend. If the sound is too 'thin,' you have not set the frequency high enough; if the sound becomes 'boomy' you have set the frequency too high. Adjust until you find the most natural balance. 6. Turn the Subwoofer Level control completely counterclockwise to its minimum. 9
