RME Audio - ADI-2 DAC

rmi adi-2 dac

Ultra-Fidelity PCM/DSD 768kHz DA Converter The ADI-2 DAC from RME features an enhanced SteadyClock, finely-tuned analogue circuitry, a brand-new MRC remote control, ‘Extreme Power’ headphone out and an exceptional IEM output. Featuring all the hallmarks that made the ADI-2 Pro so widely acclaimed, including its wonderfully clear signature sound and full capability of DSP processing, with 5 band EQ, crossfeed and much more.

The ADI-2 DAC now features more streamlined, intuitive operation, aswell as a beautiful new aesthetic design, it truly is the perfect centrepiece for any audio lovers home.

An Evolution

rmi adi-2 dac

A whole host of new and improved features The ADI-2 DAC is an evolution of the ADI-2 Pro, optimised for home and hi-fi use. With a host of new, exciting and innovative features and a number of handy functionalities, the ADI-2 DAC quickly became the reference. With thanks to its combination of pro-level DA conversion, with dual IEM outputs and remote control, it has been acclaimed worldwide with lauding reviews for its versatility, sound and technical efficiency.

Fast forward to now, the current version of the ADI-2 DAC ships with a newly designed remote control, enhanced DA conversion and an adapted analogue output stage for even greater noise and distortion values. To account for the ADI-2 DAC’s intended home use market, RME changed some of the Pro’s studio functionalities for one’s which would better suit home and hi-fi use. Featuring an adapted list of features and simplified overall operation, RME is proud to present the ADI-2 DAC. Built and designed on the lauded technology and concept of the ADI-2 Pro, the DAC now focuses on DA conversion in ultra-high quality, alongside exceptional dual headphone and IEM outs.

The Ultimate DAC

Nothing comes close Inside the compact 19” format factor, the ADI-DAC 2 is packed with only the highest quality electronic components, which acts as a reference class conversion from SPDIF coaxial, SPDIF optical (ADAT compatible) and USB to RCA, XLR, TRS and mini-TRS.

rmi adi-2 dac

The ADI-2 DAC is the most versatile DAC on the market, it offers balanced/unbalanced analogue I/O’s, an ‘Extreme Power’ headphone output, an incredibly super low noise IEM out, 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. Nothing else comes close.

Super Low Noise For IEM lovers

rmi adi-2 dac

Super low noise floor The dawn of the headphone revolution brought not only headphones, but IEM’s to the forefront for audiophiles and music aficionados alike. Today’s IEM’s have a reference that can compete with traditional over-ear headphones, which make them not just an alternative for when you’re on the go, but also for home use.

Modern day IEM’s are super sensitive and run on extremely low voltages. The downside to this is that they pickup the noise floor of the source. When RME was developing it’s ‘Extreme Power’ headphone stage, great care and attention was paid to ensure the noise floor was as low as possible. RME wanted to ensure that even the most sensitive IEM, coupled with the most sensitive listener’s ear could enjoy the whole dynamic range upon playback.

The solution? Adding the most advanced IEM output possible as second phones connection to the front panel of the ADI-2 DAC. The resulting playback must be heard to be believed.

Hit The Lights!

AutoDark Mode If a studio converter’s display had all display lighting off, you’d be forgiven for thinking it was faulty. However, on a DAC it was one of the most requested features RME received from their ADI-2 Pro HiFi customers. The ADI-2 DAC’s display, function keys, volume knob and standby button all switch off after a period of 10 seconds of no user operation after ‘AutoDark’ mode is selected. Using the ADI-2 DAC’s remote, ‘AutoDark’ mode can be selected on or off, and pressing any button turns the lighting on for 3 seconds. A cool feature for sure!

SteadyClock FS

rmi adi-2 dac

impressive new tech The ADI-2 DAC marks a first for a product in RME’s range, as it is the first to feature SteadyClock FS. SteadyClock really couldn’t be improved upon much, it collected heaps of praise and accolades from years of sublime operation in a number of RME products, ensuring that using the internal clock will produce precisely the same sound as if an external one was to be used. SteadyClock expertly rejects jitter and handles all digital interface formats in a flawless manner. This is why SteadyClock’s design didn’t alter in the DAC. SteadyClock FS focus was largely placed on reducing the self jitter of SteadyClock to new lows, by enhancing it’s second analogue PLL circuit, and referencing both Direct and Digital Synthesis and PLL to a low phase noise quartz crystal. The self jitter measured through DA conversion now reaches levels that are normally only available in master quartz clock mode, while SteadyClock still always runs in PLL mode – no matter if it's the internal or external clock, the sound is precisely the same. The low phase noise oscillator which drives the updated circuit reaches jitter specs lower than a picosecond, something called, ‘Femtosecond’, hence the name ‘SteadyClock FS’.

RME ADI-2 DAC fs - Extreme Power Headphone Amplifier and Reference Class USB DAC, SPDIF Coax and Optical Inputs is rated 5.0 out of 5 by 5.
Rated 5 out of 5 by from Pro DAC for the audiophile Stop worrying about audiophile DACs and their esoteric internal architectures and just listen to unadulterated uncoloured neutral data bits! Read the reviews and forum comments and then just buy it - it’s full of features you may never use, but straight out of the box there’s enough revolutionary tried and tested pro technology in there to satisfy the most discerning listener - if you must colour your sound then be like me, do it further down the chain after this amazing DAC does it’s stuff :D

Rated 5 out of 5 by from Read the Manual! The adi-2 dac is an amazing piece of hardware but it's potential would only be realised if the user understands the plethora of functions buried in its menu/submenu trees. The provided manual goes extensively through each of these functions and additionally provides tips and guides on specific things the user may want to achieve. My only regret with my adi-2 dac was not getting the black edition pro version instead. If your input needs is only with digital ins, then the adi-2 dac is the way to go. However if you think you may need the dac to have analogue inputs as well, then do consider the pro variant. 1 thing I would've wanted changed on the adi-2 dac is the port layout at the back. I wished the xlr ports were placed directly side by side of each other instead of being divided by the rca ports. But this is to do more with my cable management peeve rather than a fault of the design tho.

Rated 5 out of 5 by from Superb DAC The online reviews are excellent. This DAC sounds amazing, clear and faultless with streaming hi definition music used as DAC and pre-amp via my Rega Exon 3 power amps and Rega R9 speakers. Much better than my previous DAC

Rated 5 out of 5 by from Best Bang per buck DAC Great little DAC. Has all the inputs you'll need be it USB, Coaxial or Toslink. It doesn't have an AES balanced in or an I squared s but those weren't important to me but be aware just in case you want one of those inputs. I bought it for its DAC function & I'm more than happy with its performance as to my ears it sounds just that little bit more clear than my older Arcam D33, my Devialet D200 expert & my Linn Majik DSM DAC'S did. I have used the headphone Amp on it & to my ears that also sounds really good. I haven't used the DSP ability of this little thing though & don't plan to so unfortunately I can't comment on that side of things. All in all its a great small DAC in its price point & I feel that you will have to get into the £1k+ territory of DAC'S to beat it for sound quality. It's built well & looks the part too. Overall I'd highly recommend this DAC to pro users or Hi-Fi lovers alike no problems.

Rated 5 out of 5 by from Probably best in class If you want a DAC/preamp/headphone driver for audio reproduction, this is a very good choice. (There are other RME products that are more suited for audio production like the ADI-2 Pro from which the ADI-2 DAC is derived.) You can find reviews linked at the RME website so I will just give my personal experience here, especially on some less obvious operational details. The unit is powered from a small brick style power supply; connector locks when rotated. Control is via IR remote control or 3 clickable rotary encoders (larger one for volume and smaller ones marked [1] and [2]) and 4 buttons on the front panel. Click a button and press up [1] or down [2] to go up or down the menu. Rotate [2] to change the highlighted item. Rotating [1] changes the submenu or there is no action if there is no applicable submenu. Not very intuitive to start with but you'll soon recognise the pattern and be able to navigate through the many options. There is a partial menu map in the included ring-bound User's Guide. You can also find overview and menu walkthroughs at RME's Youtube channel. Volume control is in 0.5 dB steps from +6.0 max down to -84.5 dB (far preferable to some gear I've used which have progressively larger steps as you turn the volume down - makes it difficult to set the correct level at low volume). Below this, steps are a bit variable (digital rounding?) but inaudible already so doesn't bother me. I use the unit with my computer connected via USB. It works with the native Windows drivers. If you install the optional RME driver (needed to update firmware), you can use their Digicheck software which will give you level meter, spectrum analyser, vector scope, etc., on the computer screen. With very low output impedance, it is rated to drive loads down to 8 ohms with output power up to 500 mW. I use it to drive my speakers directly! It's loud enough for my near-field low-moderate level listening. I just made up some speaker leads soldered to a standard 6.3 mm TRS jack plug.

Hi there, I wanted to check if the version you are selling has the new AK4493 DAC chip or the older AK4490. Many thanks

Asked by: Jez801
I bought my unit in July and can confirm that it's the new version as it came with the updated remote, the amber light option, and the +18 dBu gain. I will note that that rear left rca port color resembles the AK4490 (black colored port) instead of a white colored port as shown in brochures of the AK4493 chipped units.
