8 Channel MADI / AES Converter

RME complements its MADI series with the ADI-642, an 8-channel MADI from / to AES converter. Up to 192 kHz at 24 bits are supported. The ADI-642 contains an easy-to-use 72 x 72 routing matrix, with which any input channel can be assigned to any output channel. Both the 64 MADI and the 8 AES channels are thus freely configurable.

The compact device is used for format conversion from MADI to AES and back. MADI offers 64 channels of 24-bit audio at up to 48 kHz sample rate, 32 channels at up to 96 kHz, and 16 channels at up to 192 kHz. The transmission takes place over a single line, either coaxially (BNC) or via an optical network cable. In both cases, a cable length of more than 100 meters can be achieved. The AES channels are provided via 4 AES / EBU inputs and as many outputs on XLR. The ADI-642 understands the MADI formats 56 channels, 64 channels as well as 96k and 192k frames at the input, and can also generate these formats optionally at the output. It offers itself as a link between otherwise incompatible MADI devices. The ADI-642 is compatible with MADI interfaces from Sony, Merging, Lawo, Euphonix, Stagetec, Jünger, Audio Service and AMS.
