ART 311

The 311 Crossover may be used as a stereo 2-way crossover network and has 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 is 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 (250hz to 6khz). 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 50hz to 250hz range.
