RME / M-1620 Pro

The latest AD/DA converter, the M-1620 Pro, defies conventional wisdom, delivering RME's uncompromising high-end quality at an unbeatable cost-performance ratio.

■AD/DA Converter
■MADI / ADAT / AVB/Milan Compatible

The M-1620 Pro is an innovative AD/DA converter and digital patchbay router featuring 16 analog inputs and 20 analog outputs, seamlessly converting and integrating line-level signals into MADI, AVB/Milan, and ADAT.

It features a newly designed front panel with highly visible LED meters and displays, channel-specific +13/+19/+24 dBu input/output level switching, two independent headphone outputs, cutting-edge converter circuitry and flexible internal routing, RME's proprietary jitter suppression technology ""SteadyClock FS,"" and redundant MADI, network, and power connections*. All of this is packed into a mere 1U rack space, setting a new standard for building next-generation immersive studios.

The M-1620 Pro delivers outstanding performance in any professional environment, from immersive audio playback and multi-channel recording to live PA, post-production, broadcast facilities, and high-end audio system construction.
* Redundant MADI and power supply configurations require optional components, sold separately.

Key Features
- 16 analog input channels, 16 analog output channels (D-sub 25-pin)
- Adjustable reference level for each analog input/output channel: +13 / +19 / +24 dBu
- Two independently controllable TRS headphone outputs for monitoring all input signals (analog/digital)
- Four selectable anti-aliasing filters (Sharp / Slow / Short Delay Sharp / Short Delay Slow)
- Seamless MADI redundancy (available with optional optical MADI SFP module)
- MADI to AVB/Milan conversion
- Two RJ45 Gigabit Ethernet AVB/Milan channels, 8 bidirectional streams (up to 128 channels), 1 to 8/12/16 channels, redundant
- Fully redundant power supply (available with optional external power adapter)
- SteadyClock FS: Ultra-low jitter digital clock technology

SyncCheck & ICC: Instantly switches to another available clock source if the clock source fails

Control knobs and a 2-inch full-color display provide easy access to all functions

Freely route any input source to any output

All settings and routing changes can be made from the front panel or via web remote

Remote control via IEEE 1722.1 ATDECC / JSON OSC API / network or USB connection

Seamless Integration of Analog, MADI, and AVB/Milan
The M-1620 Pro features ADAT, AVB/Milan network (supports Gigabit Ethernet), MADI (coaxial and optical with optional SFP module), and analog inputs and outputs, seamlessly integrating digital and analog signals in a single unit.

The converter section features an anti-aliasing filter setting that optimizes the impulse response and frequency characteristics. Combined with RME's proprietary SteadyClock FS technology for jitter suppression, this delivers extremely precise and clear sound quality, combining the high resolution and stability required for professional audio environments.

In addition to the MADI coaxial connector, a separate BNC connector for word clock is also provided. Furthermore, the extensive analog I/O enables reliable audio transmission and flexible system construction for immersive studios, live environments, and recording engineers utilizing a wide range of outboard gear.

High-Quality Analog Inputs and Outputs
The M-1620 Pro combines the high sound quality and flexible input/output configuration required for professional environments, with 16 analog inputs and outputs plus two headphone outputs.

Analog inputs and outputs are connected via D-Sub connectors on the rear panel, and the reference level can be individually set for each channel: +13, +19, or +24 dBu (at 0 dBFS). While this function is typically implemented using digital trims, the M-1620 Pro processes in the analog domain, allowing for optimal level matching without compromising the converter's S/N ratio, even when switching to line level.

In addition, each channel can be remotely changed or muted, supporting fast and flexible operation in the field. Technical Specifications
