RME ADI 6432 R Bidirectional 64-Channel MADI/AES Format Converter

Convert 64 MADI Channels to 32 AES EBU Interfaces

The RME ADI-6432 R is a professional 64-channel digital audio format converter designed to link MADI and AES/EBU environments with maximum flexibility and performance. With support for the full MADI bandwidth—64 channels at 48 kHz, 32 at 96 kHz, or 16 at 192 kHz—this 2U rackmount unit serves as a powerful solution for broadcast studios, live sound networks, or facility-wide digital routing. Whether you’re interfacing with an HDSPe MADI system or building a MADI-based digital multicore, the ADI-6432 R makes large-scale signal management reliable and precise.

Full Redundancy for Power-Dependent Applications

The "R" version of the ADI-6432 is purpose-built with dual power inputs to maintain continuous operation across two independent AC power sources. If one power circuit fails, the device seamlessly continues operating without signal interruption. This redundant power capability makes the ADI-6432 R ideal for mission-critical installations such as broadcast operations centers, live touring racks, and high-availability studio environments.

AES and MADI Format Conversion with Versatile I/O

Equipped with eight 25-pin D-sub connectors (32 AES inputs and 32 AES outputs), the ADI-6432 R directly converts MADI streams to AES/EBU and vice versa. The MADI connection supports both coaxial BNC and optical fiber formats, with automatic input switching for redundancy. The unit accommodates both 56-channel and 64-channel MADI formats, as well as 96k frames, ensuring compatibility with legacy and modern MADI configurations.

Built-In Clock Management and Signal Sync Tools

Featuring RME’s proven SteadyClock technology, the ADI-6432 R eliminates jitter and restores high-quality clock signals across your setup. Whether you’re clocking from AES, word clock, or MADI, this unit regenerates and stabilizes timing to maintain phase alignment. SyncAlign and SyncCheck ensure flawless channel synchronization and immediate detection of timing discrepancies across devices and protocols.

Comprehensive Signal Status and Control Display

The front panel features an ultra-detailed sync and audio state monitor with 97 LEDs, providing immediate visual feedback on signal flow, sync status, and data integrity. Each function has a dedicated control key and indicator LED, allowing for hands-on configuration without guesswork. All settings can be locked to prevent unintended changes during critical sessions or installations.

Stackable Configuration with MIDI and RS-232 Control

Multiple ADI-6432 R units can be used in tandem for expanded routing needs or fully digital multicore solutions. Remote control is supported via both MIDI and RS-232, allowing you to adjust settings or monitor device status from a central control surface. Additionally, the unit supports MIDI and RS-232 signal pass-through over MADI, reducing cabling and streamlining communication across digital systems.
