English 4. EQ: There are three program-specific equalization settings: Loud, Deep, and Flat. See Selecting EQ Modes on page 17 for more information. 5. Display Brightness: Pressing this button toggles the display brightness. Available settings are Max, Dim1, Dim2, and Off. 6. Low-pass filter up/down: The low-pass filter can be adjusted from 40Hz to 150Hz. If the subwoofer is connected via LFE, increase the low-pass filter until "LFE" appears on the front display. Adjusting for Best Performance In an ideal audio system, the subwoofer works "invisibly", simply adding deep, loud bass without calling attention to itself and blending seamlessly with the main speakers so it appears that the main speakers are making all the sound. The key to seamless main speaker/subwoofer blending is finding the perfect crossover frequency, equalization, and phase settings for your system. The best place to make those "set and forget" adjustments is from your listening chair via the wireless remote. If your receiver has built-in Audyssey or a similar auto setup/ room correction function, run that first. In most cases that is all the adjustment you will need. NOTE: The auto setup functions work best when the subwoofer is connected to the LFE/subwoofer output. 1. Sit in your favorite listening position with remote in hand. 2. Play a piece of music you are very familiar with that has good deep bass content. 3. Adjust the volume up or down to taste. The bass should have impact without sounding too "heavy." 4. Using the Subwoofer Low-Pass Filter Guide on page 18 as a starting point, adjust the LP up or down until there is a smooth transition between the main speaker and subwoofer. Play a recording with male vocals and string bass. Turn down the LP filter frequency until the vocals sound rich but not "thick" or "chesty." Turn it up if the vocals sound "thin" or lacking in body. 5. Push the Phase button on the remote control to adjust the Intelligent Phase Control setting on the subwoofer. Then listen to how well the subwoofer blends with your speaker system by how little you can tell the difference of sound coming from your speakers and subwoofer. This may also fix some unevenness in the frequency response of your system. If you can't hear a difference between settings, it is recommended that you leave the setting on 0 degrees. 16
