Perfectly Suited for Singer/Songwriters and Instrumentalists, Access Online Content, and Learn Faster

With four simultaneous inputs and support for mics, electric guitar/bass, and line-level devices like keyboards and drum machines, Rubix44 allows music creators to capture mix-ready performances in a single pass. Singer/songwriters can record vocals and stereo instruments at the same time, and acoustic instrumentalists can connect up to four different microphones to capture every nuance of their sound.

Top-Quality I/O to Support Your Creative Flow with a Compact, Space-Saving Footprint

Rubix44’s stellar mic preamps are low noise and high definition, with plenty of headroom for capturing all the impact and detail of whatever you’re recording. The flexible combo jacks and Hi-Z inputs let you connect a variety of sources including mics and guitars, with no need for adapters or special cables. Four individual outputs enable sophisticated routing and monitoring possibilities, like sending a click to a performer, setting up a stage monitor, or routing audio to external gear.

Control and Enhance Your Sound with Analog Compression and Limiting

Highly dynamic sources like percussion instruments often need level taming with dynamics processing. It’s also common to apply compression on vocals and bass while tracking to even out levels and make these sources easier to mix. Rubix44 is equipped with panel-accessible compressor/limiters on inputs 1/2 and 3/4, ensuring good, hot signals without clipping and unwanted distortion. The dynamics processing is completely analog, providing smooth and transparent control with zero added latency.

Monitor Signal Status at a Glance, Even While Performing

When recording, achieving proper signal levels is critical. But studios and stages can be dark places, and you don’t need to deal with clip and level indicators that are small and hard to see. Designed with recording performers in mind, Rubix44 features bright indicators that clearly show if a channel has incoming signal or is going to overload. Better still, they can be seen from both the front and top of the unit, allowing you to easily monitor signal status from nearly anywhere you’re located.

Dedicated Monitor Controls and Seamless Integration with Mac, Windows, and iPad

On its front panel, Rubix44 features quick-access knobs for adjusting the overall volume and headphones level, plus dedicated Direct Monitor controls for latency-free monitoring without having to fuss with a computer-based mixer. Mac and Windows drivers deliver smooth, reliable performance, and the included Roland Cloud Pro membership provides a complete creative platform that works right out of the box. Rubix44 even supports iPad, giving you a powerful, compact system for on-location recording, mobile production, and gigging.

* Although Roland has tested numerous configurations, and has determined that on average, a computer system similar to that described above will permit normal operation of the Rubix, Roland cannot guarantee that a given computer can be used satisfactorily with the Rubix based solely on the fact that it meets the above requirements. This is because there are too many other variables that may influence the processing environment, including differences in motherboard design and the particular combination of other devices involved.
