Cosmotronic COSMIX
8-channel analog stereo mixer with warm dual-band drive
22 HP Eurorack module
COSMIX is an 8-channel analog stereo mixer for Eurorack featuring four mono channels and two stereo channels with panning and aux send per mono channel. Its defining character comes from a built-in dual-band analog stereo maximizer with separate high and low saturation faders, feeding into a diode clipping circuit that adds warm, gluing saturation to the full mix. It is designed for live performance with clickless mute switches and flexible pre/post fader aux routing.
