Lifeforms System Interface
Flexible Six Channel Audio Hub
Sold Out

 

Packed with deep signal routing options and high quality preamps, the System Interface is a flexible audio hub, perfect for both studio and live performance. Squeezed into 24hp.

The System Interface is a six channel mixer with three channels featuring high quality preamps and stereo panning. Signal routing options include a post level auxiliary send with stereo aux return, and independent assignable bus and main mix sends. Headphone output can be assigned to the main mix, bus, or both.

Preamps on channels 1, 2, and 3 offer 15x of clean gain with a unique soft clipping overdrive circuit. They are perfect to raise the level of external, line level gear to modular levels or to dirty up an already modular level signal. Channel 1 has a dedicated output designed to allow it to function as an input for external sources without hogging the bus or aux send. 

Because most mixes do not require each channel to have a full complement of features, channel 4, 5, and 6 share auxiliary, bus, and main mix controls allowing for maximum channels within a small footprint.

Three independent signal paths open the mixer up to complex routing possibilities. The auxiliary send can be used as an effects send or alternative mix while the bus is used to cue up sounds for live performance or to split the mixer channels into 2 independent mixers. The possibilities are deep.
