Reference class DA converter for PCM 768kHz/DSD 11.2MHz

A top-level product that combines some of the features of the ADI-2 Pro installed for professionals with simple operability and excellent sound quality that are easy to use even for users who are new to audio. Was born as a DAC/headphone amplifier.

Crystal of technology
Width 215mm, depth 150mm, height 52mm, footprint smaller than B5 size, height is about 5 CD cases. In the compact body, the best components for achieving the highest sound quality are carefully selected, and SPDIF coaxial (coaxial)/SPDIF optical (ADAT compatible)/USB input, RCA/XLR/TRS/mini-TRS Provides reference quality DA conversion to the output. In addition, SPDIF input signals can be recorded via USB.

Equipped with balanced and unbalanced two analog outputs on the back, you can select the optimum reference level in 4 stages according to the connected equipment such as speakers and amplifiers.

Operates with an external power supply adapter, the voice processing is done on a DSP basis, and the newly developed SteadyClock FS that further updates the SteadyClock III, which boasts a highly accurate jitter removal function, is equipped with a class compliant mode (CC mode) Supports OS standard driver on Mac and iOS (iPad, iPhone) by adopting. For Windows, it provides a well-established dedicated RME ASIO driver and can be used with WDM and ASIO.

PCM and DSD playback
PCM supports playback up to 768kHz/32bit. Not only can you enjoy high-resolution audio sources by connecting it to a PC or iOS device, but you can also connect a device that supports digital output to the SPDIF or ADAT input and use it as a hub for AV devices, and use devices such as CD players, TVs, and Blu-rays. If you connect it, you can enjoy contents such as CDs and movies with the best sound quality. The display has a status bar that allows you to quickly check the clock source and sample rate, allowing you to quickly check the audio signal and body information. With the included remote controller, you can comfortably switch input sources with the touch of a button.

DSD supports playback up to 11.2MHz and supports DSD in various forms. When DSD signal is input from USB or SPDIF input, DAC automatically switches to DSD mode. The rear panel analog output supports DSD native playback and is equipped with a high-frequency noise filter that suppresses audible out-of-band noise.
RME's Windows ASIO driver supports ASIO native as well as DSD in DoP format.

Extreme Power headphone output/IEM in-ear monitor output
The headphone output can be used as a reference for all types of headphones, from over-ear headphones to earphones, providing the highest quality unbalanced signal. Extreme Power headphone output (6.3mm standard) and ultra-low noise IEM output (3.5mm mini jack) output from two independent driver circuits optimized for high/low impedance headphones, connect headphones, earphones, It provides the optimum output level according to the in-ear monitor.

High resolution IPS display
The display is equipped with a number of convenient functions, such as the adoption of an "analyzer" based on the highly acclaimed RME DIGI Check Spectral Analyzer, and operation of the main body, clock information, audio signal display and main body settings. You can The screen brightness/hue can be changed, the background color can be changed to black (Dark mode), and all LEDs can be turned off automatically (AutoDark mode).

Analog output and volume control
The analog output on the rear panel has a built-in high-quality analog relay circuit that sends the optimum level signal to the connected equipment, and the reference level in the range of 18 dB can be switched in 6 dB units. In addition, it has Auto Ref Lev mode in which the reference level switches according to the output level, optimizing the SN ratio when using the VOLUME knob.

RME's 42-bit TotalMix technology digital volume control produces the highest quality sound with faithful output of the original sound without distortion over 190dB.

High quality EQ and professional mastering function are operated comfortably

Equipped with high-quality 5-band parametric EQ compatible with 768 kHz. The EQ adjusts the difference in sound quality between devices, calibrates the speakers and the room, and uses the Dual EQ that can adjust the EQ of each LR, and is also useful for correcting the left and right audio imbalance due to hearing impairment.

In addition, the functions such as phase, mono, stereo width, M/S processing, etc. that are standardly installed in the RME interface can be used for all analog outputs.

Configurable loudness function
Loudness is a function that corrects the human hearing sensitivity that changes with frequency and volume, but the loudness can set the maximum gain value of the base and treble that is corrected as the volume is lowered. You can also set the volume value at which each gain reaches its maximum. By making appropriate settings according to the user's hearing and taste, you can experience the loudness processing that is as natural as if it had worked from the beginning.

Crossfeed emulation
Equipped with a crossfeed function to meet the needs of users who want to enjoy headphone monitoring with a sound image close to that of a standard speaker setup. The cross feed can adjust the stereo width of the high range by 5 steps by the Bauer binaural theory. The ambience component that produces a proper stereo image by outputting from the speaker may sound like an unnatural image different from the speaker when listening with headphones, but using the cross feed function gives a more natural ambience feeling. can do.
