Designed to meet the demanding requirements of professional studios, immersive sound installations, live-sound systems, and industrial applications, theRME M1620 PRO-Dconverts 16 analog line-level signals (per channel switchable up to +24 dBu) to and from popular digital formats like MADI, ADAT, and Dante. It offers exceptional 24-bit /192 kHz audio quality thanks to its precision converters and proprietary SteadyClock FS technology, which ensures minimal jitter and a pristine signal path.

Built with reliability in mind, the M1620 PRO-D features redundant Dante and MADI connections, plus two redundant power supplies with monitored DC input, ensuring uninterrupted operation during mission-critical applications. This compact, 1 RU rackmountable unit boasts a user-friendly front panel with LED level meters, a display, and dual headphone outputs for convenient monitoring. Additionally, the M1620 PRO-D’s versatile routing capabilities and extensive control options make it a powerful tool for both recording and live-sound applications.

Simplicity at First Glance, Flexibility and Reliability Beyond

• RME prioritizes reliability by equipping the M-1620 Pro with built-in redundancy. This includes dual-network and dual-MADI connections, along with a monitored DC input in addition to the internal AC power supply.
• A unique system clearly signals when an issue arises, ensuring seamless operation. With full standalone capability, users can adjust device settings directly on the unit for quick modifications or to recall entire user-defined presets.
• The M-1620 Pro D integrates 64-channel, bidirectional Dante connectivity, providing direct links to other audio devices via standard Ethernet switches. If redundancy is not required, the device can act as a switch itself and allow daisy-chains of several Dante devices.
• Users can record and playback up to 64 channels of any of the M-1620s analog and digital I/O on their computer using Audinates Dante Virtual Soundcard (license not included).

Add Analog and Dante I/O to Any Existing MADI Devices

• The M-1620 Pro allows manual configuration of the converters aliasing filters for optimal impulse and frequency response. Jitter on digital input signals is effectively reduced with SteadyClock FS.
• Separate word clock BNC and coaxial MADI connectors (with optional optical MADI via an SFP module), allow the device to be easily integrated into existing infrastructure.

Plug & Play, Rapid User Interaction

• Users can control all device states directly from the front panel for convenient, direct access to all features.
• RME network audio devices can be reached over network (including wirelessly over Wi-Fi) and USB for convenient remote access, allowing the rapid creation of gain groups, phantom-power switching, and clock configuration.
• In addition, a JSON-based API and even SysEx MIDI commands can be used to integrate each model virtually anywhere.
• The integrated routing matrix allows single-channel routing across all analog and digital I/O, making problem-solving of signals, clocking, connectivity, or other issues both simple and straightforward.

SteadyClock FS, Reference-Class Digital Clocking

• Small fluctuations of the clock frequency are referred to as “jitter”, measured in nanoseconds (ns). The effects of jitter on the audio signal are many, from a somewhat rough sound quality to diminished treble localization, to clicks and dropouts in extreme cases.
• To solve these issues, RME has developed a proprietary technology for synchronization and jitter suppression in digital audio signals called SteadyClock.
