Essential Information About the Roland Rubix24 USB Audio Interface
- 24-bit / 192 kHz High-Resolution Audio for clear, detailed, and faithful recording and playback.
- Two combo XLR / 1/4-inch jack inputs with +48 V phantom power and Hi-Z mode on input 1 for guitar or bass.
- Direct monitoring and dedicated controls (level, output, headphones) to record without being distracted by latency.
- Compact and robust design, designed for home studios and mobile setups (Mac, PC, and iPad).
A Rubix Interface Designed for Portable Studios, Without Compromising Signal Cleanliness
The Rubix24 follows the spirit of the Rubix series: offering a USB interface that is easy to integrate but capable of delivering clear, defined, and production-ready sound. Roland has especially refined the audio chain "from input to output" to maintain a very low noise level, a crucial point when layering takes (vocals, guitars, synths) and aiming for a clean mix right from recording.
Who It's For and In Which Uses the Rubix24 Makes a Difference
The Roland Rubix24 is aimed at musicians, beatmakers, podcasters, and producers who want a reliable 2-input / 2-output sound card to record a voice and an instrument, or two simultaneous sources. Thanks to the MIDI connectivity (IN/OUT), it also integrates very well into a keyboard and machine-oriented studio. Its USB operation facilitates mobility, and its iOS compatibility allows building a compact setup with an iPad to compose, record, and create demos anywhere.
Key Features for Efficient Recording, Streaming, and Producing
Preamps, Hi-Z, and Phantom Power: True Input Versatility
The two combo inputs accommodate microphones (XLR) and line/instrument sources (1/4-inch TRS jack). Activate +48 V for a condenser microphone, or Hi-Z on input 1 to plug in a guitar directly with the correct impedance. The SENS controls per channel allow quick gain adjustment, while the level indicators help avoid clipping.
Practical Tools: Comp/Limit, Loopback, and Ground Loop Management
For more controlled takes and live content, the Rubix24 includes functions rarely this accessible: COMP / LIMIT (with type selection), LOOPBACK to send computer audio back into your stream, and a GROUND LIFT switch useful for reducing hum in certain setups. Add to this the DIRECT MONITOR, MONO mode, and headphone source selection, and you get an interface designed to record and monitor your listening with precision.
