STM – Stereo to Mono Switch: It provides an extra stable Real Analog Mono Base for your mix (on monos like Kick/Bass/MainVox/Snare and so on), saving precious digital-to-analog (DA) channels (so you don’t waste stereo L/R for a mono instrument), and offers superior separation and 3D depth for the rest of your stereo instruments. This feature turns L/R inputs ‘COMBINED’ (two hard-panned L/R inputs) into an absolutely centered mono signal (1 x stereo to 2 mono). For example, ‘SNARE’ on channel 1 (left), ‘KICK’ on channel 2 (right). Mono instruments in the DAW sequencer (Steinberg cubase, pro tools, flstudio, reaper, logic pro, Ableton etc.) should place the kick hard left, the bass hard on the right, and so on. Stereo instruments: If you don’t use mono channels in your mix, simply turn down all the mono switches, and you’ll have a fully stereo analog summing mixer with panning options available from the DAW.
