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

Introduction

The Roland Rubix44 is a 4-in/4-out USB audio interface designed for musicians and producers. It offers high-fidelity sound with support for up to 24-bit/192kHz audio resolution, ensuring clear and defined recordings with extremely low noise. Its robust metal construction provides durability, while its compact size makes it suitable for both studio and portable use. The Rubix44 is compatible with Mac, PC, and iPad, providing versatile connectivity for various music production environments.

Key features include four low-noise mic preamps with XLR combo jacks, a Hi-Z input for guitars and other high-impedance sources, MIDI In/Out ports, and an onboard hardware compressor/limiter. Ground lifts are included for quiet operation, and large, easy-to-read indicators provide essential information at a glance.

Setup

Before connecting your Rubix44, ensure your computer or iPad meets the system requirements. Install the necessary drivers from the Roland website for optimal performance, especially for Windows users. Mac and iPad users may find it class-compliant, but driver installation is still recommended.

Connecting to Your Computer/iPad

1. Connect the Rubix44 to your computer using the provided USB cable. The interface can be bus-powered via USB.
2. For additional power stability or when connecting to an iPad, use a 5V DC power adapter (not always included, check package contents).

Connecting Microphones and Instruments

• Microphones: Use XLR cables to connect microphones to the INPUT 1L, 2R, 3L, or 4R combo jacks on the front panel.
• Guitars/Basses: Connect instruments with high impedance (e.g., electric guitars, basses) to INPUT 1L or 2R using a 1/4-inch TS cable. Activate the Hi-Z switch for the corresponding input.
• Line-Level Devices: Connect keyboards, drum machines, or other line-level devices to any of the combo jacks using 1/4-inch TRS or TS cables.
• MIDI Devices: Connect MIDI keyboards or controllers to the MIDI IN and MIDI OUT ports on the rear panel using standard 5-pin MIDI cables.

Operating the Rubix44

Input Controls

• SENS (Sensitivity) Knobs: Adjust the input gain for each channel (1L, 2R, 3L, 4R). Turn clockwise to increase sensitivity. Monitor the signal indicators to avoid clipping.
• 48V Phantom Power: Press the 48V button to supply phantom power to condenser microphones connected to the XLR inputs. An indicator light will illuminate when active.
• Hi-Z Switch: Engage this switch for INPUT 1L or 2R when connecting high-impedance instruments like electric guitars or basses.
• COMP/LIMIT (Compressor/Limiter): The Rubix44 features a hardware compressor/limiter. Use the THRS (Threshold) knob to set the level at which compression/limiting begins. The COMP/LIMIT indicator lights up when active.

Monitoring and Output

• DIRECT MONITOR: This switch allows you to hear your input signal directly through the outputs with zero latency. It can be set to MONO or STEREO.
• OUTPUT Knobs:
  • The large OUTPUT knob controls the overall volume of the main outputs (1/2 and 3/4).
  • A separate knob controls the volume for the headphones output.
• Signal Indicators: Bright, easy-to-read indicators show input signal levels, helping you monitor your audio and prevent clipping.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Avoid abrasive cleaners or solvents.
• Storage: Store the Rubix44 in a cool, dry place away from direct sunlight and extreme temperatures.
• Cable Management: Ensure cables are not excessively bent or strained to prevent damage to the connectors and the unit.

Troubleshooting

• No Sound/Weak Signal:
  • Check all cable connections.
  • Ensure input SENS knobs are adjusted correctly and not too low.
  • Verify that the 48V phantom power is engaged for condenser microphones.
  • Confirm the Hi-Z switch is active for high-impedance instruments.
  • Check your computer's sound settings and DAW (Digital Audio Workstation) to ensure the Rubix44 is selected as the input/output device.
• Humming or Noise:
  • Engage the GROUND LIFT switch on the rear panel. This can help eliminate hum caused by ground loops.
  • Try connecting the unit to a different USB port or power outlet.
  • Ensure all cables are properly shielded and in good condition.
• Driver Issues:
  • Reinstall the latest drivers from the official Roland website.
  • Try a different USB cable or port.
