SKU: LA67_.LR4 Crossover Maker: Types: ,


Voltage controlled 3-way crossover with 24/db filter slopes.

A three-way crossover under voltage control. Two four-pole state variable filters in series allow an input signal to be split into three non-overlapping bands, while the fourth-order Linkwitz-Riley slopes provide ideal band separation. And because both filters are full range, the bandwidths are arbitrary, not range-restricted.


  • 24dB/oct filter slopes
  • Fourth-order Linkwitz-Riley response curve
  • 20hz-20khz range for both filters
  • Individual CV inputs for both crossover points
  • Inverting attenuators on CV inputs
  • “L/M CV” input normalled to “M/H CV” input
  • Exponential CV response


  • 6hp
  • 20mm depth
  • Current draw: 45mA/45mA  +12v/-12v
  • Reverse power polarity protection
