SteadyClock FS

The ADI-2 DAC is the first device in RME's range with SteadyClock FS. There is not much to improve with SteadyClock, it has earned its accolades over years of flawless operation in numerous RME devices, guaranteeing that using the internal clock will produce exactly the same sound as when using an external one. SteadyClock highly rejects jitter and handles all digital interface formats in an exemplary way. That's why SteadyClock's design and behavior didn't change in the DAC.

With SteadyClock FS the focus was put on reducing the self jitter of SteadyClock to new lows, by improving its second, analog PLL circuit, and referencing both Direct Digital Synthesis and PLL to a low phase noise quartz crystal. The self jitter measured through DA conversion now reaches levels that usually are only available in master quartz clock mode, while SteadyClock still always runs in PLL mode - no matter if internal or external clock, sound is exactly the same (again). The low phase noise oscillator driving the updated circuit reaches jitter specs lower than a picosecond (ps), an area called FemtoSecond. Hence SteadyClock FS.

Bit Test

A bit test is used to check the playback path for unwanted changes in the playback data. Playback software can cut bits, add dither, or change the level - without these changes becoming noticed easily. A poorly programmed driver can manipulate bits, and a playback hardware could be both badly designed and defective (hanging bits, swapped bits). Even such features as proper channel assignment, left/right synchronicity and polarity can be tested by a well-made bit test.

The ADI-2 DAC is the home and hi-fi optimized version of the ADI-2 Pro, a studio AD/DA converter of the highest quality. With many fresh ideas, innovative features and numerous useful functions, the ADI-2 DAC quickly became the reference. Thanks to its combination of high-end DA conversion with two exceptional headphone IEM outputs and a remote control, it has received countless enthusiastic reviews for its sound, flexibility, and technical capabilities.

The current version of the ADI-2 DAC comes with an extended remote control, a further improved DA conversion and an adapted analog output stage for even better noise and distortion values. To address the home and HiFi users, RME exchanged some of the Pro's studio features with typical home and HiFi ones. With an adapted feature set and much simplified operation RME proudly presents the ADI-2 DAC. Built on the technology, concept and features of the ADI-2 Pro, the DAC concentrates on DA conversion in top high-end quality, along with two exceptional headphone and IEM outputs.

The DAC
Note about the current ADI-2 DAC
At the end of 2020 a fire destroyed AKM's production facilities for AD and DA converter chips. A resumption of production and thus availability of these components is not expected before 2022. Therefore, many manufacturers - like RME - are forced to either discontinue products based on AKM chips, or to use other chips for the foreseeable future.
The ADI-2 DAC was initially based on an AK4490, later on the AK4493. The current unit uses an ES9028Q2M for its high-quality DA conversion. This chip is very similar to the AK4493 in fea- tures and technical specifications, which allows RME to continue offering the ADI-2 DAC in its well-known supreme quality, and with a nearly identical feature set.
Even though this chip is a central (sometimes sole) quality determining element, the ADI-2 DAC is just not a normal DAC. Tech specs and features are based on RME technologies, and they are available unchanged also with the ESS chip:
- Complete DSP functionality (PEQ, Bass/Treble, Loudness etc.).
- All sample rates, PCM as well as DSD
- All digital formats (SPDIF/AES/ADAT)
- Analog output circuitry, including Auto Ref and 2.5 dB digital headroom ?Very fast switching between different sample rates
- Extreme Power headphone output stage
- SteadyClock FS, including the latest 1 Hz filter technology ?Remote, display, general behavior, operation and handling....

ADI-2 DACs with AK4493 and ES9028Q2M are neither sonically nor visually easily distinguisha- ble. However, the ESS version is recognized by a small C at the end of the serial number sticker (B stood for AKM 4493). Furthermore, the units differ in the available filters. The unit with AKM has a filter called Short Delay Low Dispersion, while the one with ESS has a filter called Brick- wall (the other filters, SD Sharp, SD Slow, Sharp, Slow, NOS, are identical). Further Chip de- pendent differences are mentioned in this manual.
But now we wish you exquisite listening pleasure and a lot of fun with the ADI-2 DAC!
