'A Match Made In Tonal Balance Heaven'
'accuracy, phenomenal soundstage, width and detail'Tom has analysed the HD800S using our GRAS artificial ear and has generated the perfect EQ settings for the ADI-2.
"The HD800S matches fairly well our target frequency response to begin with, but with these few minor tweaks, it's really on the money and shows the magic of this bundle. This should provide a very even, well balanced response, but If you would prefer more treble then decrease the gain cut on the treble band, or for more bass, add in a bass band shelf at 115Hz and adjust gain to taste.
The combination of accuracy, phenomenal soundstage, width and detail in such a lightweight headphone is truly a thing of beauty. Don't forget to use the Crossfeed function to bring the stereo field to sound like speakers if you are mixing or if certain instruments such as stereo acoustic guitars sound too wide."

A Multitude of Devices...
...compressed in one HousingThe ADI-2/4 Pro SE is a 2-channel analog input to digital and 4-channel digital to analog output converter in a half-rack (9.5") enclosure of 1 U height. Latest 32 bit / 768 kHz converters offer up to 123 dBA signal to noise ratio. Reference class tech specs throughout are combined with an unprecedented feature set. A powerful DSP adds all kinds of useful audio processing, including 5-band parametric EQ, fast Bass/Treble adjustment, Crossfeed, and a new concept in Loudness sound control.
The ADI-2/4 Pro includes two servo-balanced analog inputs on combo XLR / TRS jacks, two separate balanced and unbalanced outputs on XLR and TRS, two stereo Extreme Power headphone outputs on the front for easy balanced operation of all headphones, including IEMs via Pentaconn connector.
Also available are optical SPDIF I/O, which also understands ADAT, as well as coaxial SPDIF (RCA) and AES I/O (XLR) via an included breakout cable. This universal set of I/O options offers superior quality and flexible connectivity to those who take a no-compromise approach to audio.
With independent balanced outputs for Line and Phones, balanced phones no longer mutes the rear outputs. Balanced Line and Balanced Phones outputs can be used simultaneously, even with different sources/signals. The balanced TRS in the back can be fed from Line 1/2 or Phones 3/4 signal path, perfect for handling insert effects during the mastering process.
A high resolution IPS panel for the graphical operation surface eases operation even more, and displays further functions provided by the DSP, namely Peak level meters, a 30-band analyzer in DIGICheck biquad filter technology, and a State Overview screen listing the current states of SPDIF, AES, USB and clock.
The USB 2.0 port is fully Class Compliant (UAC 2.0) a standard that is natively supported by operating systems like iOS, macOS, Linux and Windows 10 (since 1709), and is also used for firmware updates. Including an external switched power supply with lockable connector, the ADI-2/4 Pro can be easily powered from battery, opening up mobile applications as well as galvanically isolated use cases.
As a computer interface the ADI-2/4 Pro offers a stereo (2 in / 2 out) and a multichannel mode (6 in / 8 out). Compatibility with macOS comes right out of the box. Under Windows the ADI-2/4 Pro uses RME's MADIface series driver, for full WDM and ASIO compatibility and highest performance.
Even More Flexible & Powerful
choice of power supply is not criticalThe new Trigger Out socket provides a 12 V switching signal via 3.5 mm mono jack plug, which can be used e.g. to switch power amps with Trigger In on and off together with the ADI-2/4 Pro.
In order to make operating the ADI-2/4 Pro SE as flexible as possible, the unit has a universal DC input socket, accepting voltages from 9.5 Volts up to 15 Volts. An internal switching regulator of the latest technology with high efficiency (> 90%) prevents internal hum noise by operating above audible frequencies. Internally the switching regulator is followed by standard linear regulators, followed by super low-noise linear regulators. Therefore the ADI-2/4 Pro SE achieves its technical specs even with less optimal power supplies. Or in other words: the choice of power supply is not critical.
Shortly after the release of the original ADI-2 Pro we received many requests for digitizing vinyl records. Thanks to MM (Moving Magnet) compatibility, the ADI-2/4 Pro SE does not require an external preamplifier anymore and can directly connected to turntables. It has suitable input impedance, RIAA equalization, and the necessary preamplification.
Extreme Power Headphones
The new Reference in Accuracy and Dynamic RangeRME’s developed Extreme Power headphone stage is now further improved and delivers incredible more powerful headphone outputs (2.1 Watts unbalanced, 3.4 Watts balanced at 32 Ohms, per channel). With a Special IEM mode, the Lower noise Extreme Power design adds additional IEM power states (High power, Low power, IEM) for full IEM compatibility.
All three phones outputs feature mute relay, over-current detection, DC protection, plug detection and DSP control, like auto assigning volume, volume ramp up, auto balanced mode, dual phones mode, user interaction at overload detection, and low impedance level meter auto scaling.
RME’s latest True Balanced mode realizes balanced phones operation independent from the XLR outputs. The device now features 2 balanced input channels and 4 balanced output channels. Balanced headphones only use DAC channels 3/4 and the rear outputs can still output an independent signal via DAC 1/2. In True Balanced mode the ADI-2/4 Pro SE’s maximum output level rises to +7 dBu for IEM, +13 dBu for Low Power, +25 dBu for High Power. The signal to noise ratio stays unchanged.

Sennheiser - HD 800 S
The new standard for critical listeningThe Sennheiser HD 800 S headphones bring together the care dedicated to a handcrafted instrument and the precision of modern manufacturing, the HD 800 S allows you to explore your entire music collection from the inside out. After launching its predecessor - the HD 800, Sennheiser gave themselves the challenge to completely disappear from the last link in the audio chain, with the aim of providing acoustics so immersive that your awareness dissolves into the creator’s perspective. Each and every component of the HD 800 S is world-class. The signature sound of the HD 800 S is possible not because of a single component, but through the combination of them all.

Setting The New Industry Standard
Ring Radiator transducerThe transducer leverages the main benefit of a large diaphragm transducer, which is air displacement without losing the rigidity that favourably impacts rest and response times. Instead of a single attachment on the outer circumference of the transducer, both outer and inner edges of the “ring” are secured to the drive unit. The voice coil excites the diaphragm, connected to the v-shaped groove found near the center of the ring. A feat in itself, the voice coil is 40mm and wound in-house to ensure the shape and consistency is held to the highest standard.
complete stabilityEvery transducer is manufactured, tested, and measured to the highest tolerance to ensure the most dependable performance out of the box. The steel mesh found in the baffle is also matched and integrated with consistency as a priority, as it adds to the ultra-low variance in the management of travelling sound waves. Each HD 800 S includes the frequency response plot unique to those perfectly matched transducers, sparing no resource to help you hear the most vital nuances from every section of your music collection.
Mesmerizing Soundstage
perfectly matched transducer systemsA result of several key features, the drivers are mounted at a precise angle, guiding the sound directly to the listener’s ears at their natural inflection point. Instead of hearing a sound that forms between your ears, you hear a vivid blend of frequencies and sensory-stimulating transients.
When combined, the vibration damping chassis, perfectly matched transducer systems and wide-open construction work in concert to provide the most impressive soundstage yet. This orientation rivals or exceeds loudspeaker setups costing exponentially more, especially when room acoustics are factored in. The HD 800 S gives you a personal concert hall on-demand, without disturbing the neighbours.
Advanced Sound Reproduction System
Incredible ExtensionGaining acoustics that are true to the source also requires management of compounding frequency clusters that produce undesirable masking effects. Sennheiser integrated a patented frequency absorber, which is a principle similar to that found in the breakthrough IE 800S, to reduce resonances that hide extraordinary musical details in plain sight.
The transducer system is also mounted in a vibration damping chassis using aerospace-grade materials. Together with the previously mentioned headband, the problematic energy peaks of lower frequencies are managed to display the purity your hi-fi setup is capable of.
An Ergonomic Treat
Ultra ComfortEvery contact point utilizes ultra-soft microfiber padding, while purpose-made composites reduce weight and unwanted pressure. Each earcup offers dual-axis articulation, as soon as you put them on the HD 800 S will instantly and seamlessly conform to your unique structure. The result is an incredible listening session that never stands in the way of your passion for hi-fidelity sound reproduction.
