DiGI-MK3 – USB audio interface AES/EBU/DI

Overview

AUDIOWERKEUG DiGI-MK3 is a high-quality, two-channel USB audio interface with three galvanically isolated outputs (Toslink/RCA S/PDIF, XLR AES/EBU). It was developed to enable high-quality digital transmission of audio signals from a computer to a professional sound system. Despite offering a wide range of options and functions, many commercially available sound cards often do not provide galvanically isolated AES/EBU, S/PDIF RCA and Toslink outputs. This often results in interference, humming, poor transmission quality, or low output levels. DiGI-MK3 is designed as a plug-and-play device and uses the standard drivers of the operating systems, meaning it is class-compliant and uses the power supply of the USB interface.

FAQ

Which operating systems are supported by the DIGI-MK3?

The DIGI-MK3 is compatible with Windows, Mac OS, as well as Linux starting from Kernel 2.6.

Do I need special drivers to use the DIGI-MK3?

No, the DIGI-MK3 operates as a plug & play device and uses the standard drivers of the operating systems. No additional driver installation is required.

Which digital outputs are available?

The interface offers three galvanically isolated digital outputs:
– Coaxial S/PDIF output (RCA, 75 Ohms)
– Optical Toslink output (Toshiba F05 connector)
– AES/EBU output (XLR)

What does galvanic isolation mean and what are its benefits?

Galvanic isolation separates the electrical connection between source and destination devices, preventing interference such as hum or noise. This ensures a noise-free and distortion-free signal transmission.

Do I need a separate power supply for the DIGI-MK3?

No, the DIGI-MK3 is fully powered via the USB interface and does not require an external power source.

What are the maximum cable lengths for the digital outputs?

Maximum cable lengths depend on the output type:
– Coaxial (RCA): up to 10 meters
– Toslink (optical): up to 5 meters
– AES/EBU (XLR): up to 100 meters (depending on cable quality)

Can I use the DIGI-MK3 with any PA system?

The DIGI-MK3 is designed for professional PA systems with digital inputs (S/PDIF, Toslink, or AES/EBU). Your system must support the corresponding inputs.

What resolution and sample rate does the DIGI-MK3 support?

The interface supports resolutions up to 24 bit and sample rates up to 96 kHz to ensure high-quality audio performance.

Is the DIGI-MK3 suitable for studio environments?

Yes, due to its high-quality galvanically isolated outputs and stable signal transmission, the DIGI-MK3 is well suited for professional studio applications.

How do I connect the DIGI-MK3?

Simply connect the DIGI-MK3 to your computer via USB. Then connect the digital outputs with appropriate cables to your PA system or digital mixer.
