RME MADIface XT II – 394-Channel Triple MADI USB 3.0 Audio Interface

The RME MADIface XT II is the latest high-performance audio interface designed for complex studio and live sound applications. With an incredible 394 channels at up to 192 kHz, it excels at handling large-scale recording and mixing projects, such as orchestras, drum kits, and multi-instrument setups. This interface offers pristine sound quality with redesigned digital and analog circuitry, providing an improved signal-to-noise ratio and ultra-low distortion, making it ideal for professional audio production.

Connectivity is comprehensive and versatile, featuring two mic/line preamps with phantom power, balanced XLR line outputs, headphone output with increased power, multiple MADI inputs and outputs (optical and coaxial), MIDI, AES/EBU, and word clock I/O for precise synchronization. Its USB 3.0 interface ensures plug-and-play operation with Class Compliant mode, offering driverless compatibility across many operating systems.

The included software suite with TotalMix FX, DigiCheck Analyzer, and TotalMix Remote empowers users with extensive routing, monitoring, and creative DSP effects including EQ, dynamics, reverb, and delay. The MADIface XT II also supports an optional ARC USB remote for tactile, hands-on control of the mixer and effects.
