The XO2, 2-in 6-out audio management system from XTA in collaboration with Funktion One, offers advanced processing capabilities and improved performance along with extra features as standard.


  • Extended processing capabilities - 9 (previously 5) full bandwidth parametric bands available on every output all switchable between PEQ, high and low shelving responses.
  • Further extended processing capabilities - crossover filters on each output now offer 48dB/Oct. responses, on top of the previously available 12 to 24dB/Octave options. A gentle 6dB/Octave roll-off response is also now included.
  • Flexible routing matrix available - in addition to standard fixed configurations such as 2 x 3 way (standard configs are still implemented) any output may be fed from any input or the sum of inputs. Edit buttons show routing instantly when pressed.
  • Delay memory allows for up to 650mS from any input to any output - extra fine delay resolution on outputs for driver alignment, in 30nS (0.1mm) steps!
  • Library manager software available for design of OEM presets - design your crossover live whilst connected to the unit and lock out any parameters as required to prevent end user adjustment/viewing. No practical limit to the number of presets that may be stored (over and above the user memories).  



  • 2 inputs and 6 outputs - native processing now runs at 96k resulting in wider bandwidth (over 30kHz)
  • Improved converters - lower noise and improved distortion figures
  • Legendary XTA look ahead limiters with automatic and manual time constant facilities
  • Stylish Funktion One look
  • Extended memory capacity - user memories now extended from 9 to a maximum of 255
  • Bigger 2x24 character display with new low profile buttons
  • Auto switching power supply works across the world on all voltages
