Connect to Cubase

Using Cubase, the AXR4 reaches its full potential, thanks to its ability to record and playback in 32-bit integer format. It seamlessly integrates with Cubase via the mixer’s customer hardware panel, with users also benefitting from additional features like auto-setup, enabling the complete I/O setup to be handled directly from within the DAW.

Cubase AI included

The AXR4 comes with a free copy of Cubase AI, a basic but well-featured version of Steinberg’s industry-leading DAW. The AI version offers a one-stop solution for studio-quality recording, with the same audio engine as the popular Pro version.

Full DAW integration with dspMixFX AXR

Seamlessly integrating with Cubase and most other DAWs, the AXR4 delivers latency-free monitoring with DSP-powered effects, via the onboard DSPX chip and latest dspMixFX technology. This provides a fully integrated, DSP-based monitoring setup in any situation, irrespective of the DAW you use.

The mixing application for the AXR4 makes the setup of the unit with your chosen audio production software very straightforward, with full access to all necessary routing and controls. A metering window also provides an excellent overview of all input and output levels.

Full control with a 28x24 matrix mixer

The dspMixFx AXR application allows for setup and control of the AXR4’s DSP mixer and DSP effects. A full 28x24 matrix mixer has been incorporated to satisfy professional-level monitoring and system-related requirements, for example routing inputs and DAW or system audio to a mix bus. Five different windows give comprehensive control over all settings: the mixer, the matrix mixer, the meter, show/hide channels and settings. This guarantees an excellent overview of all levels and routing at all times. These settings can be saved to the AXR4 to recall different scenes, depending on the chosen workflow.

Raising the bar for professional-quality sound

The AXR4 audio interface raises the bar for professional-quality sound to a new level. At the core of the interface is the high-speed data throughput necessary for professional-level recording, with a vast array of inputs and outputs providing all the connectivity that high-end audio set ups demand. Four combo inputs are equipped with digitally-controlled state-of-the-art hybrid mic preamps, each with switchable Rupert Neve Designs SILK technology for the most musical sound possible. As well as the four combo inputs, the comprehensive range of 28 in, 24 out options include 8 TRS line inputs and 8 TRS line outputs, 2 x 8 channel ADAT/S/PDIF (or 1 x 8 ADAT and 1 x 8 AES/EBU) and a future-proof digital I/O card slot. Word clock, MIDI I/O ports and twin headphone sockets with independent volume controls are also provided. With 32-bit integer recording at up to 384 kHz, DSP-powered, latency-free monitoring, advanced SSPLL jitter suppression and a flexible 28x24 matrix mixer, the AXR4 is a truly exceptional audio interface for studios, producers and professional musicians.

Flagship hybrid microphone preamps with Rupert Neve Designs sound

The microphone preamplifiers at the input stage of every audio interface provide the fundamental character of the overall sound. The AXR4 features extraordinarily natural-sounding hybrid microphone preamps, developed by Yamaha, which are available for use on all front input channels. Developed as part of Yamaha’s “Natural Sound” philosophy, the choice of components, mechanical construction, circuit layout, power supply and grounding were all painstakingly evaluated and refined in the AXR4. Final adjustments were made after extensive aural tests by both Yamaha experts and eminent outside engineers, resulting in a totally new design that is genuinely worthy of “flagship” status.

Rupert Neve Designs SILK

Recording engineers have used microphone preamps designed by the legendary Rupert Neve for many years, giving their sound a highly appealing touch of natural compression and saturation. SILK processing adds power and flair to take that exquisite sonic quality to new levels, giving sounds that tend to get lost in the mix new life and intensity.

The SILK processing function provided in the AXR4’s hybrid microphone preamplifiers offers two choices, Red for sparkling energy, and Blue for solidity and power. In addition, a continuously variable Texture control musically shapes the harmonic components to best suit the sound source. The benefits of SILK processing are also evident in the way channel EQ and reverb plug-ins affect the sound.

SILK can be used on all mic input channels, either to specific channels or to all mic input channels to add depth and perspective to the overall mix.

SSPLL: The latest virtual jitter reduction technology

As more devices with clocks are added to an audio system, a problem arises as the clock of each beats against the others, creating additive audio band jitter. The traditional solution to this problem is to add expensive master clocks with VCXOs and sample rate conversion. However, thanks to audio equipment becoming more affordable, some manufacturers use cheap clock solutions which, in some cases can lead to equipment stopping working properly. The newly developed SSPLL™ (Super Suppression Phase Locked Loop) performs on the same level as traditional, expensive clocking solutions used in professional clocking products. SSPLL is currently the most advanced technology for virtually removing audio band jitter, it is highly robust and extremely tolerant of wide variations in clock frequencies. Using SSPLL makes all of the connected equipment work reliably and virtually jitter-free.

32-bit integer/384 kHz AD/DA conversion

High-quality conversion is a crucial first step to a great audio production. With the AXR4, Steinberg’s designers invested a huge amount of time, effort and meticulous research in choosing the very best combination of components, to create the ultimate analog to digital conversion currently available in an audio interface. We have set a new standard by including 32-bit integer converters, which capture the subtlest nuances of every recorded signal in the most precise, transparent manner. Thanks to this exceptional resolution, even the tiniest audio detail is maintained throughout the entire production process.

We have raised the bar further with a sample rate of up to 384 kHz, allowing the reproduction of transients, the stereo image and the recording environment to be much more detailed, while the anti-aliasing filter can be set at a level where it won’t be heard.

DSP-powered effects

Powered by Yamaha’s custom-designed next generation DSPX chip, the AXR4 features the benefits of dspMixFX AXR technology for latency-free monitoring, as well as the acclaimed Sweet Spot Morphing Channel Strip, REV-X reverb and the Vintage Classics VCM Compressor 276 and VCM EQ601. When using Cubase all the advanced monitoring capabilities are fully integrated into the application’s GUI by True Integrated Monitoring technology.

The right choice for creatives and professionals

The AXR4 can connect to a huge range of musical instruments and audio equipment, making it an ideal interface for any professional sound application. With +48 V phantom power available on all four XLR/TRS combo inputs, both condenser and dynamic microphones are accommodated, while all four inputs can also accept line level signals. Inputs 1 and 2 can accept Hi-Z signals, so electric guitars and basses, MIDI equipment and any kind of studio equipment or playback device can all be used. With a range of analog and digital output options and up to three units able to be daisy-chained via Thunderbolt 2, the AXR4 has all the connectivity required for professional production situations.
