TRUE-BLUE BOX MODULES

True-Blue Box. Sound as it was meant to be; The true-blue sound.

Are you a passionate Do It Yourself music lover and do you want to create your own amplifier or active speaker?

Or are you an audio manufacturer and are you looking for compact, affordable and modular amplifier modules? Then the True-Blue Box COBALT modules may be something you have been looking for!

Our new True-Blue Box COBALT modules will bring you to the essence: music experience at the best. You’ll be amazed at the musical details you’ve never heard before in your favorite music!

The fast ADC’s and patented Axign feedback loop of the AX5689 make it possible to exceed the audio performance of large and very costly pre,- and power amplifiers and DAC combinations for only a fraction of the amount you need to pay for a traditional high end audio set-up.

The True-Blue Box COBALT module system consists of:

  • Power Amplifier Module – 2x100Watt in 8 Ohm power stage and feedback loop
  • DA Input Module – input module with 2x optical, 1x USB, 1x line level (balanced or unbalanced, 1x phono (balanced or unbalanced)
  • UI Module – User interface module with LED input indicators, Rotary encoder with on/off switch and IR sensor.
  • SPA Module – Fixed gain input module balanced or unbalanced input. *
  • Power Amplifier Module XL – 2x200Watt in 4 Ohm powerstage and feedback loop. *
  • DA XL – Input module with 3x Optical, 1x USB or coax, 3x line level (balanced or unbalanced) and 1x phono (balanced or unbalanced). *

* = in development

For specific derivatives of the modules above and modifications to the existing modules, we are happy to talk.
