ครอสโอเวอร์ dbx 224XS

Stereo 3-Way Crossover (XLR) Connector

- อุปกรณ์ปรับแต่งเสียง ครอสโอเวอร์แบบ 2/3 ทาง สเตอริโอ
- 4 ทาง โมโน

DBX 223XSV, 24dB/octave Linkwitz-Riley filtersx10 range switch on both channels, 40Hz highpass (low cut) filter both channels, subwoofer output, XLR inputs and outputs

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.

Features:

• XLR balanced ins and outs
• Mode switches for mono 4-way or stereo 2-way/3-way operation
• Low frequency summed (subwoofer) output
• x10 range switch on both channels
• 40Hz high pass (low cut) filter both channels
• Phase reverse switch on all outputs
• Individual level controls on all outputs
• 24dB per octave Linkwitz-Riley filters (the professional standard)
• Stereo/Mono status LEDs indicate the selected mode
• dbx® 2 year parts and labor as standard
• CSA NRTL/C approved
• CE compliant
