Ultra-fidelity PCM/DSD 768 kHz DA Converter

Skickas direkt från leverantör.

The ADI-2 DAC includes an improved SteadyClock, a fine-tuned to  perfection analog circuitry, new MRC remote control, Extreme Power  headphone output and a very special IEM output. It has all the bells and  whistles that made the ADI-2 Pro famous, including its perfectly  transparent sound signature and full DSP processing with Bass, Treble,  Loudness, 5 Band Parametric EQ, Crossfeed and much more. With its  simplified operation and stunning design it is the ideal center piece  from home listening up to studio reference playback.

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.

ADI-2 DAC Features



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, SPDIF optical (ADAT compatible) and USB  to RCA, XLR, TRS and mini-TRS.

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.

Improving DA

The updated ADI-2 DAC uses AKM's AK4493 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  -116 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 -121 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  behavior 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.

Super Low Noise for IEM lovers

The headphone revolution not only brought headphones but also IEMs  (in ear monitors) back into the attention of audiophiles and music  lovers. Modern IEMs have a reference sound that easily competes with  bulky over-ear headphones, making them not only a mobile alternative,  but also an interesting solution in home.

Modern IEMs are extremely sensitive and operate on very low voltages.  As a side effect they uncover the noise floor of the player, DAC or  headphone amp. When RME developed its Extreme Power headphone stage the  basic noise floor was taken care to be as low as possible. Which was  then confirmed in many reviews (most black background…). Even when used  with IEMs.

Still RME wanted to make sure that even the most sensitive IEM  combined with the most sensitive listener receive the full dynamic range  on playback. Also capable outputs like the Extreme Power ones are not  fully safe against operating errors and might blow up ears or IEMs.

RME's solution: adding the most advanced IEM output imaginable as  second phones connection to the front of the ADI-2 DAC. Its ground noise  floor is an astounding 10 dB lower than the one of the Extreme Power  output (black hole background…), output impedance is near zero Ohms, THD  reaches new record lows, click-free on/off is included as well as  volume ramp-up, and the sound quality with any IEM is just amazing. We're sure you will love it!

Lights Out!

A studio converter with all lights off? Defective. But on a DAC it  was one of the most often requested features from our ADI-2 Pro HiFi  customers. Here we go: display, function keys, volume knob, even the  standby button - they all go off after 10 seconds of no user operation  when AutoDark is activated in the unit's menu. Touching any button or  control will turn on all lights for 10 seconds. Using the remote  AutoDark can also be switched off / on, and using any button on the  remote turns lights on for 3 seconds. Once again: we're sure you will  love it!

Special features

The ADI-2 DAC comes with a remote that is not the usual cheap add-on.  This nicely designed remote control has clearly labeled buttons,  readable even in low light conditions without reading glasses, a nicely  laid out button arrangement that is easy to remember, and perfect button  ergonomics. Plus: It won't interfere with your ATV or other devices.

New extended Multi-Remote Support (MRC)

The ADI-2 DAC remote control provides buttons for standby on/off,  volume, balance, bass and treble, input selection (optical, coaxial,  USB), mute, on/off loudness, bass/treble and EQ. In addition, there are  four programmable buttons that provide access to 32 different functions  and commands for maximum flexibility. There is no other converter or  comparable device with such a sophisticated, easy to use and at the same  time versatile remote control!

Note for owners of the previous remote: the new MRC  is also available separately as an accessory. It can be used with all  ADI-2 DACs, even older ones, if they are equipped with the latest  firmware (at least version FPGA 27, DSP 33).

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.

With a bit test, such errors can be detected and - more importantly - excluded.
