La 67 LR4 Multi-Band Crossover Filter

LA 67 LR4

The LR4 Crossover is a three-way crossover filter with voltage control that brings a new way of sculpting the frequency content of your sound in Eurorack. It features two four-pole/24dB/oct state variable filters with fourth-order Linkwitz-Riley slopes that ensure band separation. These split the incoming audio into three distinct bands, hi, mid, and low. The filters are separated into mid/hi and lo/mid which set the crossover point between the frequency bands. Both filters feature a frequency range of 20Hz-20kHz. Both filters feature an exponential CV input with dedicated attenuverters, with the L/M CV input normalled to the M/H CV input. This cross-over effect provides a novel way of filtering and dividing up the frequency content of your audio in Eurorack.
