Based on JFET filters with no feedback, it offers purely analog signal path for bi-amping applications. Low pass filter is 2-pole (12 dB/octave) adjustable from 20-300 Hz in 20 Hz steps; high pass filter offers 1 or 2 poles (6 or 12 dB/octave). All RCA inputs/outputs for stereo high pass and low pass.
