Fuse Box Unit 

Improvements of the earth in the beginning of your power supply are very effective.




The current distribution over your audio/video set-up is supported by this unit in the meter cupboard because it contributes to a better result. While developing the Black Box Harmonizer, the top model in this series, we also decided to develop a unit meant for general use. The improvement is audible!

  • The Fuse Box comes with a meter long connection cable and should be placed besides the meter cupboard.
  • Preferably connect this green/yellow cable to the same rail on which the earthing for the separate power cable of your audio/video set-up is also connected.
  • As this requires you to open the meter cupboard it is absolutely essential for your own safety that you switch off the electricity beforehand! Or let your electrician do this part.
  • Shorten the connection cable if possible.
  • Finally, mount the Fuse Box as close as possible to the meter cupboard using two self-tappers or screws
Which improvements can you expect:
  • Increased dynamics.
  • Sparkling high.
  • Remarkable improvement of the voice rendering and rendering of acoustic instruments.
  • Because high frequency noise is reduced, listening to music becomes more pleasant; listening fatigue doesn’t stand a chance.
  • Music sounds more lively, improved ´live´ feeling.


  • Dimensions: 71mm x 61mm x 30mm.
  • Weight: 240 gram.
  • Material: Shockproof anti-static ABS.
  • Connection cable: 1 meter long 2,5mm² grounding cable, colour coded green-yelllow.
