All Soundcraft Signature Series consoles incorporate Soundcraft's iconic Ghost mic preamps, directly drawn from the company's top-of-the-line professional consoles, to deliver extraordinary audio quality with high headroom, wide dynamic range and exceptional resolution and clarity with a superb signal to noise ratio. They employ Soundcraft's Sapphyre Assymetric EQ for perfectly equalizing every vocal and instrumental element in a mix with the unmistakable musicality inherent in every Soundcraft console, plus the GB Series audio routing technology famous in thousands of live venues worldwide. They all include a wide variety of built-in Lexicon studio-grade reverb, chorus, modulation and other effects and dbx limiters on the input channels. The consoles offer XLR and switchable Hi-Z inputs that enable guitars, basses and other instruments to be directly connected. All the consoles come with a 2-in/2-out USB interface. Accompanying the consoles are free downloads of the Lexicon MPX-L native plug-in and Ableton Live 9 Lite. In addition, the consoles feature smooth, premium-quality faders with GB® Series audio routing with flexible pre/post switching on each Aux, and subgroups with powerful routing and switching options as well as dedicated outputs. The Signature Series are built using tour-grade robust metal construction and top-quality components and have an internal universal power supply.
