EQ Mode
This screen is used to select two different bass emphasis settings titled “Punch” and “Depth”. They are designed to complement different types of program material, such as movie soundtracks or music. The “Punch” setting emphasizes the 55Hz region, while the “Depth” setting boosts the 30Hz range. A third setting is titled “Flat”, which defeats these two settings. Use the Left/Right touch keys to select the desired EQ setting. From this screen, press the Down or Up touch key to access other control settings.
Room Correction On/Off
This screen indicates whether the “Room Correction” filter is engaged. (See the section on “Room Correction” for more information.) Press either the Left or Right touch keys to turn this function on or off. This screen will not appear if the “Room Correction” function has not been activated, the “Room Correction” calibration was unsuc- cessful or the user memories have been erased using the “System Reset” function described under the “Save Settings” feature described in this section of the manual.
Lowpass
This screen is used to adjust the subwoofer’s upper frequency limit to achieve a proper blend with your system’s main speakers. A higher frequency (Hz) is typically used with smaller, bass limited main speakers and a lower frequency setting is customarily used with larger floorstanding models. This filter can be adjusted from 40Hz to 120Hz, as required, or defeated if the low pass filter function is being performed by your system’s electronics. Use the Left/Right touch keys to adjust the lowpass filter. To defeat this filter, press and hold the Right touch key until “Lowpass Off LFE Mode” is displayed. Refer to your surround processor’s owner’s manual for more Bass Management information. From this screen, press the Down or Up touch key to access other control settings.
Lowpass Slope
This screen is used to adjust how aggressively the subwoofer rejects frequencies above the low pass filter’s set- ting. This screen is not visible if the “Lowpass” filter above is set to “Lowpass Off LFE Mode”. There are four settings to choose from: “18, 24, 36 & 48dB/octave”. The higher the number, the more the upper frequencies are removed from the subwoofer’s output. Use the Left/Right touch keys to select the desired filter slope. Start with either the 24 or 36dB/octave setting and adjust from there if required. Adjustment of this parameter can help to optimize the acoustic blend with your main speakers. The proper setting will depend on room acoustics, your main speaker’s performance, the placement of the speakers and the subwoofer in the room. From this screen, press the Down or Up touch key to access other control settings.
Phase
This screen is used to adjust the subwoofer’s acoustic phase to match that of your main speakers. Use the Left/ Right touch keys to adjust the subwoofer’s phase from 0°to 180°. The proper setting of this control is highly dependant on room acoustics and the position of your subwoofer in the room. After setting the volume and lowpass controls, adjust the phase to 0° and listen to a recording with a prominent, repeating bass line in your intended listening position. Repeat this process with the 180° setting and use the setting that yields the greatest amount of bass output. If neither of these settings is better than the other, experiment with intermediate set- tings. From this screen press the Down or Up touch key to access other control settings.
