From Solid State Logic
Sigma is a 2U, remote-controllable analogue mix engine. Sigma has 16 stereo/mono inputs and outputs, 2 mix buses (A and B), mix bus insert points, comprehensive monitoring, a talkback input and customisable user buttons. The idea of Sigma was to bring the sound of an SSL console together with all the workflow advantages of mixing in a DAW. Sigma is built upon the same Superanalogue technology as our Duality and AWS consoles. Superanalogue circuit design gives you an extended frequency response, precise stereo imaging, clarity and depth. Sigma is designed for the professional looking to add that extra 10% to their sound, that even the best plug-in emulation cannot achieve.
Sigma features LED metering on all 16 channel strips and an additional high resolution stereo master meter. The blue rotary encoder is switchable (via a push function) between controlling the following levels: control room monitor level, headphones, Mix Bus A and Mix Bus B master “fader” gains. Many features on Sigma can be controlled using a MIDI learn. This means that you can use a generic MIDI controller to do a number of things from controlling the monitor level, to switching Mix Insert points in/out.
