The Solid 4000 rackmount Mix Buss is a new stereo processor that glues together and brings life to a mix. Based in the classic british consoles, it has the same bus circuit that the Solid 4k–500 series of the Epsilon 32–500 summing mixer. In rackmount format and very simple to use: Drive, Output and Blend controls.

​The Solid 4000 Mix Buss is designed to be used mostly as an insert on the mix bus, but can also be used to enhance instrument group busses. We suggest to insert it before you start mixing and then mix through it. This helps you tailor the mix and get the best sound.
