The Soundcraft Si Expression digital mixer allow for mixing up to 66 channels with the use of a Soundcraft Stagebox, including the newly introduced 16x8 and 32x16 Mini Stagebox, or via MADI or AES/EBU.

The three mixers are equipped with processors from other Harman Group companies (which also includes Soundcraft), including BSS, dbx, Lexicon and Studer, and you'll find touchscreen color displays, iPad ViSi Remote control feature or the FaderGlow automatic lightning technology which lights the faders with different colors depending on the assignations.
