5.5 Filter (SETuP)The Filters are used to divide the input signal into two frequency bands. This allows the userto drive the speaker in its optimum frequency range and send each output separately for moreefficient use of amplifier power. Appendix A.5 illustrates each of the available Filters. Thesignal present at the Main (OUT) outputs can be adjusted using a High-Pass filter. The signalpresent at the Subwoofer (SUB) outputs can be adjusted using Band Pass filters consistingof Low-Pass and High-Pass filters. When editing Filter parameters the frequency band isindicated by the highlighted OUT or SUB in the top left corner of the screen. The High-Passor Low-Pass filter being edited is indicated by the highlighted edge in the graphics area.For each High Pass filter there are three parameters:FrequencyAdjusts the frequency of the High Pass filter from OUT (below 20Hz) to 20KHz.TypeSelects the filter type. Selections are BW 6,12,18,24 for Butterworth type filter with slope of6, 12, 18 or 24 dB/Octave and LR12, 24 for Linkwitz-Riley type with slope of 12 or 24 dB/Octave.GainSets the gain of the selected output band. (-INFdB to +20dB)For each Low-Pass filter there are two parameters:FrequencyAdjusts the frequency of the Low Pass filter from 20Hz to OUT (greater than 20kHz).TypeSelects the filter type. Selections are BW 6,12,18,24 for Butterworth type filter with slope of6, 12, 18 or 24 dB/Octave and LR12, 24 for Linkwitz-Riley type with slope of 12 or 24 dB/Octave.5.6 Output Parametric EQ (3-band)EQ On/OffTurns the PEQ on and off.Flatten/RestoreThis parameter either flattens or restores all bands to their original settingsTypeThis parameter selects the PEQ type. Types include:Bell - All three parametrics are bell-shapedHShelf - One shelf is High, while the other two are bellLShelf - One shelf is Low, while the other two are bellLHShelf - One shelf is High, one is Low, and the other one is bell.F1 - F3 (Frequency)Selects the frequency of the selected band of the parametric EQ. (20Hz to 20kHz)G (Level)Sets the gain of the selected parametric EQ band. (-12dB to 12dB)Q (Bandwidth)Sets the Q (a measurement of Bandwidth) of the selected Parametric EQ.
