dbx 234s Stereo 2/3 Way, Mono 4-Way Crossover With Full Manufacturer's WarrantyItem Condition: [X] Barely Used (BU) - New. Opened. Used Less Than A Few Hours. [ ] Medium Condition (MC) - Almost New. Used For A Few Days. [ ] Used (U) - Not New. Box/Documentation worn.dbx 234s is a dual channel, stereo 2/3-way or mono 4-way crossover. With the 234s, 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 234s 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 234s 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 234s has 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.
