It employs state-variable 4th-order Linkwitz-Riley filter alignments to minimize phase difficulties in the critical crossover region.\u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003eThe Linkwitz-Riley alignment consists of 2 cascaded 2nd-order Butterworth filters exhibiting identical phase characteristics on their low- and high-pass outputs, guaranteeing in-phase outputs at all frequencies.\u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003eAn added benefit of this topology is steep 24dB per octave roll-off slopes. Because of the steep slopes, drivers designed to produce a specific range of frequencies, and no more, will not be driven past their limits, thereby minimizing distortion and driver fatigue.\u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003eAdjustable delay circuits are included on the low and mid outputs of each channel to compensate for any physical misalignment of the drivers. Time correction ensures the mechanical phase alignment of adjacent drivers will be acoustically correct, thus providing transparent operation.\u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003eIn 2- or 3-way stereo mode, the low outputs may be mono'ed by moving an internal jumper.
