The secret to making speakers sound great lies with the crossover you use. With the dbx 234xs Crossover you'll get great performance, ultra low-noise, rugged reliability and four decades of dbx knowledge and expertise in building the world's finest processors. The 234xs uses precision filters to separate the audio signal and direct the correct frequencies to your loudspeaker drivers. By directing only the specific frequency bands to each speaker driver the 234xs leaves your amplifiers free to use their full power on the usable signal eliminating distortion and giving your PA system a cleaner and better sound.

The dbx 234xs is a dual channel crossover with all the features you would expect from a professional product. It features Linkwitz-Riley 24dB per octave filters, independent output gain controls for level matching, output phase inversion, 40 Hz low cut filter, and optional mono summing of the low frequency (subwoofer) output. Everything in the design exudes great precision from the solid "click" controls to the high quality XLR inputs and outputs.

Great performance with ultra low-noise and rugged reliability.

    Comments about dbx 234xs Stereo 2/3 Way, Mono 4-Way Crossover:

    The sound quality of this unit far exceeds the old unit and the signal is full across volume levels. Went from a Nady 2 way stereo/summed sub output (1/4" phone jack-XLR) to 3 way stereo (XLR-XLR). Crossover points are a little different. The JBL 15's not going as low nor quite as high as before on Crown Xs1200s. The JBL 18's are carrying more load on bridged Crown Xs900s. The Klipsch pair per channel high end is sweet and clean on Crown Xs1200s. The all XLR cabling contributes greatly to the quality of the signals. Coming from a Dell 7010 using WASAPI output connected via Toslink to an Emotiva XDA-2 Gen2 DAC straight into the DBX 234XS with new studio quality XLR cables equals staying up way too late on work nights. Well worth the extra money.
