Ex-demo FF-6000(L) Funktion One/Formula Sound DJ Mixer. The mixer is in absolute Mint condition; no marks, scuffs or cosmetic damage at all. Been in a rack/flight case and used probably no more than two to three times for demo purposes. Everything looks, feels and operates as new.



  • 6 Channels
  • A removable fader panel allows the mixer to be easily
  • configured as a linear fader
  • All faders plug in and can therefore be changed easily
  • should the need arise.
  • All switches are illuminated to show system status clearly.
  • 2 push button types have been utilised to ease recognition of frequently
  • used switches.
  • Knob sizes and control spacing has been maximised



To realise the full potential of Funktion One loudspeaker systems it is of vital importance that everything in the signal path is of equivalent quality to the loudspeakers. Choosing to work with an inadequate mixer can fatally impair the performance of a system and even some of the most used models actually sound terrible. Around 2004 we became increasingly frustrated with the lack of audio quality of almost every DJ mixer in the market and resolved to do something about this. We formed a working party of Funktion One sound technicians and DJs to design a layout for a new mixer and then worked in collaboration with Formula Sound to produce the FF4000 which delivers a revolutionary combination of DJ friendliness and stunning sound quality.

Product Rating

“By far the best service I’ve ever experienced. I was importing a product to Canada and the whole experience was quick, easy and seamless. These guys really care about running a good business. Not to mention the price was cheaper than the stores here even after importing. Definitely will do more business in the future.”
