Connectivity & Features

RME ADI-2 Balanced DAC Headphone Amplifier AK4490 32bit 768kHz DSD256 Black

In 2016, RME unveiled the ADI-2 Pro. With many innovative and extremely practical ideas and features, this model has transformed the digital-to-analog conversion market into a true reference. Equipped with two Extreme Power headphone outputs, it has also found its place in the HiFi, earning numerous accolades for its sound and technical prowess as well as its flexibility.

In order to address private individuals who are lovers of high fidelity, RME offers a modified version of the ADI-2 Pro, now incorporating features adapted for HiFi listening and simplified operation: the ADI-2 DAC. Based on the technologies, concepts and features of the ADI-2 Pro, this DAC version focuses on high quality digital-to-analog conversion.

The DAC

Embedded in a compact 19" format body, this little gem integrates high-end electronic components, offering seamless conversion from SPDIF Coaxial, SPDIF Optical (ADAT compatible) and USB to RCA, XLR, Jack TRS and Mini-TRS.

Extremely versatile, the ADI-2 DAC offers balanced and unbalanced inputs/outputs, Extreme Power headphone output, very low noise IEM output, SteadyClock FS, 4-stage output level hardware control, signal processing via DSP, external power supply, wide USB compatibility and support for sampling rates up to PCM 32bit 768kHz, DSD256 and Direct DSD. The SPDIF input signals can be recorded via USB and as expected from RME, the DAC is a true 2-channel Full Duplex audio interface.

Improving DA

For the ADI-2 DAC V2, RME engineers have been working to improve the analog output stage of the DAC to provide an even higher level of performance. More relays, a modified dual symmetrical attenuator circuit and an additional AOP in buffer allow a reduction in noise and THD. Hardware output levels at +13dBu, +7dBu, +1dBu and -5dBu have also been added.

Super low noise for IEM lovers

The booming headphone market has led to many improvements not only in this type of product but also in in-ear headphones (IEMs), bringing them back to the forefront for audiophiles and lovers of quality sound. Modern IEMs offer high quality sound reproduction that can rival many headphones, making them an excellent alternative for listening on the move or at home.

However, modern EMPs are also extremely sensitive and operate at very low voltages. As a result, they tend to recover the noise from the reader, DAC or amplifier. When RME developed its Extreme Power headphone stage, the noise level was lowered as low as possible to overcome this problem.

To this, RME adds a special IEM output on the front panel of the ADI-2 DAC. This provides a 10dB lower ground noise level than the Extreme Power output with an output impedance close to 0Ω and an incredibly low THD for exceptional listening.RME ADI-2 Balanced DAC Headphone Amplifier AK4490 32bit 768kHz DSD256 Black

Lights out !

In the case of a studio device, the lights on the device are constantly on, but this can quickly become annoying in a living room. All lights and the ADI-2 DAC display will turn off when the AutoDark function is activated and no action is performed for 10 seconds. Touching any button on the device or remote control will turn the lights and display on again.

Special features

A better remote

The ADI-2 DAC comes with a rugged and convenient remote control that will allow you to easily control the unit from your sofa. In addition, it is configured so as not to interfere with your other AV devices.

This remote control allows you to turn the DAC on and off, adjust the volume level, select an input and whether or not to activate the Mute mode, and also includes 4 programmable buttons that can be assigned to 20 different functions for total flexibility.


SteadyClock FS

The ADI-2 DAC incorporates a SteadyClock FS, ensuring that the use of the internal clock will provide the same sound as an external clock. The SteadyClock effectively rejects jitter and supports all digital interface formats in an exemplary way.

Thus, the main goal of the SteadyClock FS is to reduce jitter to an incredibly low level by improving its analog PLL circuitry and linking Direct Digital Synthesis and PLL to a low phase noise quartz crystal. The self-induced jitter through the D/A conversion thus reaches levels normally only possible in master quartz clock mode, while the SteadyClock operates in PLL mode. The low phase noise oscillator driving the circuit reaches a jitter of less than a picosecond (ps), an area called a femtosecond.

Après quelques mois
Je ne retire rien de ce que j'ai déjà écrit précédemment, cet appareil est un petit bijoux de technologie.
Une remarque, question ergonomie, pourquoi avoir mis le bouton de réglage des basses au dessus de l'aigu, car il est logique de faire l'inverse, comme le sont toutes les enceintes. Une autre remarque, cet appareil chauffait beaucoup raccordé en RCA, et à présent à peine tiède en XLR (symétrique).

Petit bijoux de technologie
Cet appareil est incroyable de possibilités, convertisseur analogique, ampli casque, pré-ampli, DSP, avec des filtres pouvant adapter les écoutes à vos préférences. L'épaisseur de la notice en dit long sur la foultitude de possibilités, de paramétrages, et autres. Même la petite télécommande est sympa, et programmable pour des fonctions au choix. Je pense que les limites de cet appareil vont bien au delà de celles de la majorité de ses futurs aficionados. Des points faibles, je n'en ai vu que quelques unes, il manque une entrée I2S, il chauffe pas mal, et du fait de son très faible poids, l'appui sur n'importe quelle de ses touches, déplacent l'appareil.
Rien de bien important, ses qualités surpassent de loin ces petits détails.
A ce tarif, il n'existe aucune concurrence.
Bravo et Merci RME !

A-t-on encore besoin de le recommander?...
La référence quasi-absolue dans l'univers du DAC/ampli/preamp.

Reconnue mondialement autant par le milieu professionnel qu'amateur, on sait ce qu'on achète: C'est Made In Germany, c'est garanti 5 ans, ça mesure super bien et c'est utilisé tant en studio, qu'en conception d'ampli... et finalement dans les salons pour une simple utilisation Hi-Fi.
- Matthias Carstens de RME, le concepteur, est ultra actif sur les forums et montre un niveau d’ingénierie et de connaissance technique sans faille.
- Le firmware est régulièrement mis à jour avec des ajouts bienvenus.
- La partie préampli est vraiment un sans faute. En Auto Ref Level, on a juste accès à l'ajustement de volume le plus clean et précis que je connaisse pour driver un ampli de puissance.
- Les parties ampli casque et IEM ne sont pas en reste avec une transparence sans faille (et "suffisamment" de puissance pour 90% des casques)
- Les possibilités de DSP sont exceptionnelles, même si personnellement, je l'utilise en réglages "stock".
- Inutile de vous prendre la tête sur la "sonorité": C'est d'une neutralité et d'une transparence parfaite. Point barre.

L'avantage, c'est que quand on en possède un, inutile d'aller voir ailleurs, la concurrence est littéralement larguée. Oubliez les marques pseudo-audiophiles et leur discours marketing douteux. Oubliez l'idée qu'à deux ou trois fois plus cher, vous pourriez avoir mieux. Ici, on joue à un autre niveau... celui des pros.
