Undertone Audio Pyra-Sum Multi-buss Analog Summing Mixer

The Ultimate Hybrid Mixing Setup

The Pyra-Sum is a passive summing mixer that has what other summing mixers don’t: multiple cascading busses. This bussing architecture allows you to truly have the sound and workflow of a large format console but with even more sonic flexibility and in a much smaller format. We’ve left out any active circuitry, which means that you have total control of the coloration that’s added in the makeup gain stages-it also means you’ll need to use this with eight of your own preamps. Want a different sound? Swap the preamps. You could use Neve’s or API’s for that 70s sound. Tube RCA preamps for that 50s sound. UTA preamps for a size and musicality that has never existed before. Or, since the preamps are inserted after each stage of summing, you can mix and match- API’s on the drums, UTA preamps on the music, Neve’s on the vocals, etc. The sonic possibilities are endless.
