Steinberg AXR4 Thunderbolt Audio Interface

Audio Xcellence Redefined


Thunderbolt 2 Audio Interface with premium sound quality

With the AXR4, Steinberg sets a new standard in audio interfaces for studios, producers and professional musicians. Featuring facilities and connectivity aimed at professional-level recording, this Thunderbolt 2 audio interface significantly raises the bar, with 32-bit integer resolution and a sample rate of up to 384 kHz. The hybrid mic preamps with Rupert Neve Designs SILK emulation add exceptional tonal control, while SSPLL guarantees ultra-low jitter. The AXR4 ensures universal excellence for all recording applications.

Compatible with all major recording software

The AXR4 is compatible with all audio editing, mastering and music production software that supports the Core Audio standard. Installing the TOOLS for AXR4 is simple and seamlessly integrates the interface with your favorite DAW, with full control of settings via the included dspMixFX AXR software.

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 28×24 matrix mixer

The dspMixFx AXR application allows for setup and control of the AXR4’s DSP mixer and DSP effects. A full 28×24 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.
