dbx 223xs Stereo 2-Way/Mono 3-Way Crossover with XLR Connectors

The dbx 223xs is a precision audio crossover built on four decades of dbx engineering expertise. Its compact 1U-style chassis houses professional-grade components with solid click controls and high-quality XLR connectors, delivering the tactile confidence of a workhorse processor. This dual-channel crossover separates audio signals with surgical precision, directing specific frequency bands to their intended speaker drivers while freeing amplifiers from unnecessary signal content and reducing distortion.

Signal Processing & Filtering

The 223xs employs Linkwitz-Riley 24dB per octave filters—the professional standard in crossover design—to cleanly separate frequency ranges without phase shift artifacts. Each output features independent level control, phase inversion capability, and a 40 Hz low-frequency cut filter; the subwoofer output can sum both channels in mono, simplifying low-end management in complex PA setups.

Audio Performance & Specifications

Noise performance is exceptional: 106dB dynamic range unweighted and THD+Noise below 0.004% at +4dBu ensure transparent processing with no audible artifacts. Interchannel crosstalk measures below -80dB across the audible spectrum, guaranteeing complete channel isolation in stereo applications.
