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.
