dbx 234s Stereo 2/3 Way, Mono 4-Way Crossover

The dbx 234s delivers transparent frequency separation with surgical precision, making it an essential tool for live sound engineers and studio professionals managing complex speaker systems. Its responsive crossover points integrate seamlessly into stereo or mono configurations, allowing you to craft balanced mixes without sacrificing sonic cohesion. Built into a compact 1U steel chassis, this unit demands minimal rack space while providing the reliability and control that demanding applications require.

Audio Performance & Filtering

Linkwitz-Riley 24dB per octave filters ensure transparent crossover behavior with minimal phase distortion, critical for maintaining mix integrity across your frequency range. The 40 Hz low cut filter with optional mono summing of the subwoofer output gives you independent control over low-frequency management, This protecting drivers or optimizing sub integration in your system.

Control & Connectivity

Fully balanced 1/4" TRS inputs and outputs with differentially balanced architecture minimize noise and RF interference in professional installations. Independent output gain controls and output phase inversion on each channel enable precise level matching and phase alignment across your speaker arrays, essential for coherent sound reinforcement.
