DBX 234xs 1U Rackmount Stereo 2-Way/3-Way & Mono 4-Way Active Crossove

Multi-Configuration Versatility: Operates flawlessly as a Stereo 2-way, Stereo 3-way, or Mono 4-way active audio frequency crossover networks depending on the complexity of your sound rig. Linkwitz-Riley 24dB/Octave Filters: Utilizes industry-standard steep state-variable filters to cleanly separate adjacent audio bands, minimizing muddy overlapping frequencies between subwoofers and top mid-range enclosures. Low-Frequency Mono Summing: Features a dedicated hardware toggle switch to sum left and right low frequencies into a single mono output—ideal for centralized subwoofer array configurations.
