WHAT YOU’LL LOVE
PERFECTLY BALANCED
This subwoofer crossover is built around two banks of precision Linkwitz-Riley low-pass and high-pass filters. Multiplying DACs with monolithic ratio matching are employed to adjust the analog circuit’s filter frequencies. This offers superior tracking behavior and far more precise left/right channel balance compared to conventional approaches.
HIGH-GRADE PARTS
To minimize distortion and noise, this subwoofer crossover employs top-grade component parts in its all-analog audio circuitry: 1% precision resistors, JFET-input audio-grade op-amps, polypropylene film-and-foil capacitors and metallized polypropylene film capacitors, to name just a few.
HIGHLY ADAPTABLE
This subwoofer crossover’s input-output design makes it equally adaptable to studio, mastering suite or audiophile 2-channel playback environments. To accommodate dual-mode systems, a bypass feature engages a pass-through from a dedicated managed bass input on the rear panel to the crossover’s subwoofer outputs. This makes it convenient to switch from 2-channel to multichannel mode.
