ADI-6432R BNC

Bidirectional 64-Channel MADI/AES-3id Format Converter

  • Hi-Precision 24 Bit / 192 kHz
  • 64-Channel Bidirectional Format Converter
  • MADI – AES-3id Interface
  • MIDI embedded in MADI
  • RS232 embedded in MADI
  • MIDI Remote Control

The ADI-6432R BNC provides 64 channels of format conversion from MADI to AES-3id and vice versa. Based on RME’s highly successful bidirectional MADI-AES/ AES-MADI converter ADI-6432, the newly developed ADI-6432R BNC offers broadcasters ease of integration and fail-safe operation through the utilization of industry standard BNC connectors and dual redundant power supplies, while offering 64 channels of I/O capability.

Based on RME’s highly successful bidirectional MADI-AES/AES-MADI converter ADI-6432, the newly developed ADI-6432R BNC offers broadcasters ease of integration and fail-safe operation through the utilization of industry standard BNC connectors and dual redundant power supplies, while offering 64 channels of I/O capability. The BNC version targets broadcast and professional users who require AES-3id connections – coaxial 75 Ohm cables with up to 300m length.

Typical applications include two ADI-6432R used as digital multicore, or one unit used as AES-3id frontend for the HDSPe MADI card. Up to 192 kHz at 24 bits is supported. Built in 2 height units the ADI-6432R BNC provides enough space for all connectors and control elements.

AES-3id, an extension to the AES-3 standard also known as AES/EBU, carries the exact same data as the latter, but uses a different cable (75 Ohm unbalanced instead of 110 Ohm balanced) with different connectors (BNC instead of XLR) and lower voltage (1 Vpp instead of 4 Vpp). Therefore, the ADI-6432R BNC has 64 BNC connectors on its back.

As with every RME MADI converter, the ADI-6432R BNC provides both coaxial (BNC) and optical (SC plug to Multimode glass fiber) MADI connectors. MADI handles 64 channels of 24-Bit audio at sampling frequencies up to 48 kHz, 32 channels up to 96 kHz, and 16 channels up to 192 kHz. All channels are transferred across a single cable, either coaxial (BNC) or optical network cable. In both cases, cable lengths of more than 100 meters can be achieved. The ADI-6432R accepts 56 channels and 64 channels as well as 96k frame at its input, and can be set to generate those formats at its output.

As an option, the ADI-6432R is also available with Single Mode MADI connectors, which make the ADI-6432R BNC compatible to existing single-mode networks and to MADI signal distribution over extremely long distances (up to 10km).
