JCF audio LEVRS & ROLL MUSIC 16 CHANNELS FOLCROM SUMMING BOX

Two well kept JCF LEVRS & the Roll Music passive summing box. These surprised me when I first tried them , by making my mixes sound clear than mixing in the box, especially on a dense song chorus , there is just a bit more air around the sounds ! !So if you are looking for a clear and slightly more seperated type of sound = this is what these two do to your mixes.
They all work 100%
I'm also selling a few other items, some which are great for mixing , and one being a brand new Rupert Neve lunchbox ( to house the LEVRS )
The LEVRS were made to go with the Foclrom summing box. The Summing box is passive and so the LEVRS make up the volume.
