The ML-1 is a cardioid condenser microphone, and it models famous large diaphragm condenser mics and dynamic microphones. It offers a 20 Hz to 20 kHz frequency response with minimal distortion and is highly receptive to the included modeling software. With this interface and this microphone, you can recreate the sound and feel of many prized vintage capsules. Slate Digital VRS8 8-Channel Interface with Included Software The Slate Digital VRS8 is an 8-channel interface designed to provide a flat, linear frequency response, as well as extremely low latencies of 0.7 ms at 96 kHz. It utilizes a satellite-grade clocking system and AKM AK5578 converter chips, ensuring a stable audio performance and a dynamic range of 124 dB. Two discrete headphone amplifiers are on hand for pristine private monitoring, and two front-facing 1/4" instrument jacks accept both instrument and line-level signals. This interface is designed to be paired with separately available Slate Digital microphones to deliver what slate calls the VRS, or Virtual Recording Studio. Using this preamp, the aforementioned microphones, and included software, the VRS aims to put heretofore cost-prohibitive, holy-grail mic/pre combinations at your fingertips, with each element in the chain contributing to that goal. Slate Digital is a company well-regarded for its modeling software, and the VRS8 offers almost all of this software, some of it on perpetual basis—as is the case with the Virtual preamp collection—and the rest of it via annual licenses. In fact, a complimentary one-year subscription to the Slate Everything Bundle is included with your purchase. This package of software comprises a continuously updated suite of emulations and plug-ins, including venerable compressors, equalizers, tube-circuit modules, tape machines, consoles, mastering processors, and more. Everything from vintage and modern buttons from the 76s are represented, as are channel strips from venerated boards, and a few proprietary designs such as an Air EQ by way of Eiosis and a harmonic enhancer by way of the Revival. Using the VRS8, an ML-1 Microphone, and the Everything Bundle, you can achieve the sound of a 67 through a variety of authentic-sounding gear, such as a British channel strip, a 73-style preamp, a 76-style compressor, a de-esser, and a tape machine emulation—all in real time. This software is compatible with Mac and Windows platforms, operating in AU, VST and AAX formats. On Mac computers, the interface connects via Thunderbolt. A PCIe card is provided for use with Windows machines and other compatible computing systems. VRS8 Interface 8 Linear Preamps The start of any signal chain is extremely important, which is why the VRS8 features eight high-bandwidth Ultra Linear microphone preamps. These are of the same blank canvas design as the VMS-One preamp, enabling you to use the modeling software to recreate the authentic sound of famous microphones and preamps. Each preamp has its own high-quality metal knob, so you can easily set levels like a regular analog preamp. High-Quality Converters The next step in the signal chain is the converter itself. The VRS8 offers AKM AK5578 converter chips that provide 124 dB of dynamic range. LLN Technology In order to achieve low-latency across multiple platforms, Slate developed LLN technology, which stands for Low Latency Native. LLN utilizes a custom hardwired converter chipset, which reduces managed components in the audio path and allows an 0.7 milliseconds of latency at 96K (with a 32-sample buffer). This latency spec allows you to monitor through mic and preamp emulations while tracking, giving you the ability to hear your audio in context while still allowing you to change your mind later. XTC Audio Clock The audio clock is the heart of any recording interface, and the VRS8 is no exception with its XTC clocking technology. This clock is satellite-grade, utilizing four temperature-compensated crystal oscillators for stability, keeping your audio jitter and distortion free. Discrete Headphone Amplifiers Most engineers listen to music on headphones when working in the studio, so Slate has implemented discrete amplifiers to ensure that your headphones sound robust and clear. Not only that, Slate also added two separate monitor mixes and the ability to use the VRS8 as a speaker switcher. Cross Platform Low-Latency Performance The world of audio interfaces is rarely cross-platform when it comes to performance, meaning that Mac devices (using Thunderbolt) usually far outperform Windows interfaces (using USB). While USB can be effective for two-channel designs, it requires more CPU overhead to manage, resulting in higher CPU usage and longer latency values than Thunderbolt. Thus, the VRS8 offers both Thunderbolt and PCIe connectivity for maximum cross-platform compatibility. The PCIe performance is the same as Thunderbolt, so you can decide for yourself which connection to use. You can also link up to 6 VRS8's via Thunderbolt to achieve 48 inputs and outputs. Native MIDI I/O Unlike USB MIDI interfaces (where MIDI information has to fight with your mouse, keyboard, and other USB traffic), MIDI I/O on the VRS8 never touches the USB bus. You can count on accurate MIDI timing. Included Preamp Models More preamp models will be released, but at the very least, you get the following: FG-73: The FG-73 preamp module is modeled after a famous, discrete solid-state preamp made in Britain and used on countless recordings from the 70s onwards. It has a bold, present, and warm sound that works great on any audio source, even full mixes. FG-76: The FG-76 preamp module is modeled after a vintage German tube preamp that has been used on many classic recordings. It has a thick, colorful tone that can help enliven tracks and mixes. The bottom-end saturates in a musical way, making it a great module for bass guitar. Everything Bundle Included Software The Everything Bundle is constantly updating with new products, but at its core are the following: Audified U73b FG-Stress Classic Tubes 1 Classic Tubes 2 Classic Tubes 3 Virtual Tube Collection Virtual Console Collection Virtual Preamp Collection FG-116 FET Blue Series FG-Bomber Custom Series Air & Earth Modules Mix Bundle (FG-N, FG-S, FG-401, FG-116) The Monster Revival Trimmer Virtual Buss Compressors Virtual Tape Machine FG-X Mastering Processor

Analog or Digital - Options Galore The ADI-2 Pro includes two servo-balanced analog inputs on combo XLR / TRS jacks, two separate balanced and unbalanced outputs on XLR and TS, two stereo Extreme Power headphone outputs on the front, an optical SPDIF I/O that also understands ADAT, and 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. The USB 2.0 port is fully Class Compliant (UAC 2) for connection with compatible iOS devices, and is also used for firmware updates. Including an external switched power supply with lockable connector, the ADI-2 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 Pro offers a stereo (2 in / 2 out) and a multichannel mode (6 in / 8 out). Compatibility with Mac OS X comes right out of the box. Under Windows the ADI-2 Pro uses RME's MADIface series driver, for full WDM and ASIO compatibility and highest performance. Perfect Sound Capture and Reproduction Aiming for the absolute reference sound, any detail in the ADI-2 Pro is special and has its own story. The main PCB is an extraordinary 10 layer design with custom copper thickness, guaranteeing finest undisturbed sound as well as ample but separated power for the phones outputs. Internal power supply stages and precise regulators use a super-low-noise design to not degrade performance through the power rails. Selected SoundPlus operational amplifiers maintain highest SNR, lowest THD and high slew rate under all conditions. The whole analog circuit design is fully symmetrical and balanced throughout - and DC-coupled. The only capacitors in the signal path perform DC protection at the analog input sockets, and have been carefully selected to avoid any sonic impact. The 4-channel AD-converter, supporting 786 kHz sample rate and DSD recording, is used in a dual mono design, with 3 dB improved signal to noise ratio. Two premium DACs are used for two separate stereo outputs. Internal audio processing like EQs, Crossfeed and spectral analysis, is done by a high performance DSP with 2.17 Giga FLOPS (2882 MIPS), delivering enough computing power to work even at 768 kHz sample rate. For easy operation a high quality Sample Rate Converter has been added, switchable to the AES or SPDIF input, solving any clocking problem between those. And RME’s latest SteadyClock FS technology ensures perfect jitter reduction and stable clocking, no matter if internal or external clocks are used. High Resolution Display Operation RME have incorporated many unique features, not found on any comparable devices, like 5-band parametric EQs for fully individual phones compensation, adjustable Bass/Treble controls with quick access, a binaural crossfeed function, adjustable loudness filter, selectable AD/DA filters, four discrete I/O reference levels, auto reference level setting, auto balanced phones mode, and many more. The display is not only used to control the unit, but also shows warning and guidance messages. Professional features such as M/S Processing, stereo width and phase reversal up to full control and storage of all settings are included, as well as RME’s famous Spectral Analyzer, a 30-band biquad filtered analysis tool offering unprecedented musical visualization, perfectly complementing the high-resolution IPS display. Extreme Power Headphone Outputs There is no use in boasting about -110 dB THD, when such values are not available in real world operation - for example when a 32 ohm headphone is connected. RME's engineers therefore designed a new headphone output stage that brings the full performance of the premium DAC to the phone jack - even when using low impedance headphones. The Extreme Power design excels with 0.1 Ohm output impedance, a maximum output level of +22 dBu, and a maximum output power of 1.5 Watts - per channel! The two, fully separated stereo headphone outputs deliver the same 120 dBA SNR performance as the line outputs, for a full hum and noise free listening experience. THD is far below -100 dB (0.001%) even at full power, for the most clear and detailed soundstage possible. The Extreme Power design also incorporates current limiting, power surveillance, overload detection and DC protection. A low power mode and a high power mode are provided, for a perfect match from IEM up to planar. Having two stereo outputs, balanced headphone operation is possible. As RME's engineers were not satisfied with the existing techniques they developed a new Advanced Balanced mode for the ADI-2 Pro, that removes most limitations of standard balanced operation, and turns this mode into a a fully new experience. The exclusive Advanced Balanced mode delivers a balanced signal path from the DAC straight to the phone, with 3 dB gain in Signal to Noise Ratio, smoothed out deviations in components, optimized frequency response, super low output impedance (0.2 Ohms), and a maximum output level of +28 (twenty eight) dBu. The Anniversary Converter The ADI-2 Pro is RME’s reference AD/DA converter, USB DAC, USB interface and headphone amp. It’s numerous use cases make it an ideal choice in many fields, from the home user appreciating innovative solutions offering highest sound quality, the studio owner asking for reference AD/DA conversion, the Hi-Fi enthusiast demanding a flexible yet high-end headphone amplifier, up to the industry using the portable device as front-end for measurement systems. 20 years of RME - cumulated into a precious unit, that once heard and used one will never give away.

Connectivity and Features RME USB 2.0 2 x Phones Output Class Compliant Mode 1 x Line Output 2 x SPDIF Input Remote 1 x Stereo Chinch SteadyClock FS 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. The DAC 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.
