Roland Rubix44 4-In/4-Out USB Audio Interface

Roland Rubix44 4-In/4-Out USB Audio Interface

The Roland Rubix44 USB audio interface provides four microphone inputs, four independent outputs and recording resolution up to 24-bit/192 kHz. Its four microphone preamps, dual high-impedance instrument inputs and integrated MIDI interface support vocals, guitars, keyboards and electronic instruments. A rugged metal enclosure makes this four-channel recording interface suitable for studios and location work.

Content creators and musicians can capture multiple sources at once, such as a vocal microphone and stereo keyboard, or a small group of microphones. Each input uses an XLR and quarter-inch combination connection for flexible microphone or line-level routing. High-impedance modes on inputs one and three allow direct instrument connection. Four line outputs support external monitoring and additional signal paths without relying on a stereo-only interface.

The Rubix44 adds analog compressor and limiter processing for input pairs one/two and three/four, helping manage unpredictable transients before conversion. Hardware direct monitoring provides audio feedback while reducing computer monitoring delay. Dedicated MIDI input and output allow connection to compatible controllers and synthesizers. Roland specifies an AC-adapter power supply, USB Type-B connection, 4-pound weight and a compact enclosure measuring 12.2 by 6.5 by 1.8 inches.

Key Features

• Four microphone preamps: Record up to four microphone sources through balanced combination inputs.
• 24-bit/192 kHz conversion: Captures high-resolution sessions with multiple supported sampling rates.
• Four balanced outputs: Route monitors or external equipment through separate line connections.
• Two Hi-Z instrument channels: Connect electric guitar or bass directly to inputs one and three.
• Analog compressor/limiters: Control signals in hardware before they reach the recording computer.
• Hardware direct monitoring: Hear incoming sources without depending on software monitoring.
• MIDI input and output: Integrate keyboards, controllers and other MIDI-capable devices.
• Portable metal chassis: Provides a durable enclosure with visible signal and clip indicators.

Recording and Live Workflow

Pair the four inputs with a digital audio workstation to track vocals, acoustic instruments and external equipment. The separate outputs and MIDI connectors also support hybrid studios and stage playback systems.
