Two-way stereo crossover that features the addition of the subwoofer output for low-end frequency reinforcement. It employs 24dB/octave, state-variable, Fourth-order Linkwitz-Riley filters that guarantee properly phased outputs at all frequencies which are optimal for the proper acoustic summing of common signals from adjacent drivers in the crossover region. Each channel features independent high and low output level controls and a crossover frequency rotary control which covers a wide range (250 Hz to 6 kHz). All three outputs have a 30 cycle low cut switch to eliminate low-end rumble. The subwoofer features an independent output level and rotary control for frequencies in the 50 Hz to 250 Hz range. Dimensions: 140 x 483 x 44 mm. Weight: 2.2 kg.
