RME ADI-2 DAC FS
RME-ADI-2-DACThe RME ADI-2 DAC FS is packed into the compact half 19" format factor, this little gem is filled with the finest high-end electronics, offering a reference class conversion from SPDIF coaxial and optical (ADAT compatible) and USB to RCA, XLR, TRS and min-TRS.
This updated ADI-2 DAC uses ESS in a special circuit variant developed by RME engineers that allows the chip to perform at its best. With noise levels of 123 dBA, distortion less than -120 dB, or THD+N of -117 dB, the device delivers outstanding measured values. Even the IEM output, with -118 dBu already the world's lowest noise headphone output, improves to a sensational -120 dBu.
In addition, there is 4 dB of digital headroom, so that even high intersample peaks do not produce any audible distortion. Finally, the device now also offers a clear reserve in volume setting. +2.5 dB result in a still undistorted analog output signal.
All these improvements are completely transparent in the previous menu navigation. There are no changes in operation, features and behaviour compared to the predecessor, which is why neither appearance nor name have changed. The only difference: with 'Low Dispersion' another digital filter is available for selection. Explanations for this filter can be found in the detailed manual of the ADI-2 DAC.
As the most versatile DAC available, the ADI-2 DAC offers balanced/unbalanced analog I/Os, an Extreme Power headphone output, a super low noise IEM output, SteadyClock FS, 4-stage hardware output level control, DSP-based signal processing, external power supply operation, Class Compliant USB compatibility, sample rates up to 768 kHz as well as DSD and Direct DSD playback.
The SPDIF input signal can even be recorded via USB - as one would expect from RME the DAC is a true 2 channel Full Duplex audio interface.
