Description
For system techs who need surgical control over frequency division, the Ashly XR1001 delivers the state-variable filter design Ashly has refined since the early 1970s. Configure it as a 2-way stereo crossover for dual full-range rigs, or switch to 3-way mono for a single tri-amped stack — either way, adjacent bands stay phase-coherent thanks to Ashly’s proven filter topology.
What sets this unit apart on a rider or in a rack is the Response control sitting beside the crossover frequency knob. Rather than locking you into one fixed filter shape, it lets you dial in the damping at the crossover point itself — set it to produce a classic Butterworth curve, land on
