311
The Model 311 Crossover may be used as a
stereo 2–way crossover network, and has the
addition of a 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 mandatory
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 & rotary control for frequencies in
the 50hz to 250hz range.
