The Formula Sound System 2000 was not really a best seller, so they didn't make that many. It all might have had something to do with the fact it was pretty expensive. If memory serves me right it was in production between 1988 and 1999.
Like all high end Formula Sound Mixers it's a modular construction with three types of modules; master, mono and stereo. Input modules have a 100mm fader and three band fixed freq. eq for stereo modules and three band with sweepable mid for mono modules. Available chassis where available for 8,12 and 16 input modules, of which the 8 was 19" inch wide. The layout and functionallity is somewhere inbetween a dj mixer and a broadcast console. I guess Formula Sound was also selling this mixer to post production and radio studios. A rather hefty power supply provided +-18V for audio circuits and 6V for status lights. The last year it retailed for £225 per input module, £875 for an 8 input chassi with master module and £299 for the PSU.
