RME MADIface USB – 128-Channel USB 2.0 MADI Audio Interface

The RME MADIface USB delivers professional MADI connectivity in a compact, bus-powered interface designed for studios, broadcast, and live production. Offering 128 channels of MADI I/O via USB 2.0, it supports the format’s full 64 channels of recording and playback per port on both Mac and Windows, all with RME’s renowned low-latency performance and driver stability.

Compact and portable, the MADIface USB is ideal for high-channel MADI recording, digital routing, and system integration, or even as a stand-alone MADI format converter and repeater when no computer is connected.

Flexible Modes & Redundant Operation

The MADIface USB features two MADI inputs that can operate in redundant or dual-input configurations:

• 64-Channel Mix Mode: Standard operation for recording/playback on one MADI port, mirrored to both outputs.
• Redundancy Mode: Automatic seamless switching between inputs if the active source fails — ensuring uninterrupted operation.
• 128-Channel Mix Mode: Enables full access to both inputs for independent routing, monitoring, or pass-through applications.
• Disable TotalMix Mode: Bypasses internal routing for direct signal pass-through when required.

RME’s AutoSelect feature provides real-time input switching for fault-tolerant systems, while SteadyClock technology ensures superior jitter suppression and clock accuracy.

TotalMix FX – Complete Digital Mixing and Routing

Included with the interface, TotalMix FX provides full control over mixing, routing, and monitoring:

• Create up to 32 independent stereo submixes with zero latency.
• Distribute and split signals to multiple outputs simultaneously.
• Integrate external gear or set up ASIO Direct Monitoring workflows.
• Dedicated Control Room section for talkback, monitoring, and remote control.

Whether you’re managing complex live rigs or multiple recording feeds, TotalMix FX transforms the MADIface USB into a complete digital patchbay and mixer.

Stand-Alone Operation

When powered from any USB source, the MADIface USB operates independently as a:

• Bi-directional MADI format converter (optical ↔ coaxial)
• Signal repeater that doubles cable distance (up to 2,000 m optical / 100 m coaxial)
• Clock slave or auto-select master device for flexible sync configurations

No computer is required, perfect for field setups, broadcast redundancy, or long-distance MADI links.
