TXO-234MKII

  

  • HIGH-PRECISION STEREO 2-WAY/3-WAY/ MONO 4-WAY CROSSOVER WITH LIMITERS Professional high-precision stereo 2-way/3-way/ mono 4-way crossover.
  • World-class performance 24 dB per octave Linkwitz-Riley filters. Absolutely flat summed amplitude response, zero phase difference. Individual output level controls for all bands.
  • Individual limiter on each output for optimal loudspeaker protection. Individual output mutes for easy band adjustment.
  • Switchable 25Hz subsonic filter on each input for low-frequency driver protection. "Low Sum"function provides low-level mono output for subwoofer operation. Adjustable time delay for phase alignment between drivers.
 
  • Individual phase reverse switches for instant phase correction.
  • CD horn equalization for constant directivity horn compensation. Servo-balanced, gold-plated XLR connectors for all inputs and outputs.
  • Ultra high-precision Alps potentiometers for ultimate accuracy and repeatability.
  • High-quality components and exceptionally rugged construction for long life and relia- bility.
  • Shielded toroidal mains transformer for minimal noise interference. 
  • Shielded toroidal mains transformer for minimal noise interference.
