[. . . ] They operate in the so called Single Wire mode. ADAT Double Speed At sample rates above 48 kHz (Double Speed) ADAT uses the Sample Split method (also known as S/MUX) to be able to operate at up to 96 kHz. The data of the channels 1 and 2 will be transmitted using channels 1/2 and 3/4. The ADI-2 can receive and recombine data into 2 channels 96 kHz from all Sample Split compatible devices, like the Hammerfall, Hammerfall DSP and ADI-8 series from RME. Emphasis The ADI-2's DA-converter supports Emphasis. This control information, only found in SPDIF/AES signals, causes the converter to reduce treble. (Note: this technology was used in the early days of digital audio, and is no longer used since years). User's Guide ADI-2 © RME 9 7. 4 Digital Outputs The ADI-2 has a coaxial and an optical digital output. The key OUTPUT sets the format: · ADAT: The optical TOSLINK output operates in ADAT mode. Included support for Sample Split (S/MUX) enables sample rates up to 96 kHz. · PRO: The output signal carries the Channel Status Professional. The physical output level at the RCA connector is raised, making the signal compatible to AES-3 and AES/EBU. The same signal is found at the optical output. · CON: The output signal carries the Channel Status Consumer. The physical output level at the RCA connector is lowered. The same signal is found at the optical output. In SPDIF/AES mode, identical signals are available at both the optical and the coaxial output. Therefore up to two devices can be connected, sending the same data to two different devices (splitter). To send signals in AES/EBU format, an adapter cable is required. Pins 2 and 3 of a female XLR plug are connected individually to the two pins of a phono plug. The cable shielding is only connected to pin 1 of the XLR - not to the phono plug. The ground-free design, with transformers for digital inputs and outputs, offers a trouble-free connection of all devices along with perfect hum rejection. The optical SPDIF output can used as ADAT output (OUTPUT ­ ADAT).

RME does not accept claims for damages of any kind, especially consequential damage. Liability is limited to the value of the ADI-2.
