RME ADI-6432 Redundant

The RME ADI-6432 and ADI-6432R are professional 64-channel bidirectional format converters that bridge MADI and AES/EBU with uncompromising reliability, precision, and flexibility. Each unit converts all 64 channels of a single MADI stream to 32 AES/EBU ports-and vice versa-at sampling rates up to 192 kHz. This makes them ideal for high-capacity digital multicores, AES/EBU front-ends for MADI interfaces, or large-scale routing in broadcast and live production environments.

Built into a robust 2U 19" rack chassis, the converters feature both optical and coaxial MADI I/O, extensive clocking options with RME's SteadyClock jitter suppression, and smart redundancy, including automatic input selection between MADI ports. Advanced synchronization tools like SyncAlign and SyncCheck ensure phase-accurate, error-free operation, while a detailed 97-LED front-panel display provides instant visual feedback on sync, signal quality, and audio status.

The ADI-6432R version adds dual redundant power supplies, allowing connection to separate electrical circuits for uninterrupted operation in mission-critical workflows. Both models also support MIDI and RS232 data transmission over MADI, enabling remote control and system integration without extra cabling. With their high channel count, transparent conversion, and rock-solid reliability, the ADI-6432 series is a trusted solution for professional facilities needing seamless, large-scale digital audio interconnects.
