RME 12Mic-D 12-Channel Microphone Premplifier with Dante ADAT and MADI

The RME 12Mic-D features twelve microphone and line level inputs with digital, no-compromise, studio-quality conversion; remote controllable gains; integrated MADI and Dante connectivity; plus a multitude of additional functionality, designed for use in high-end studio recording, live audio, and location sound and music recording.

Designed for the Next Decade - RME’s preamps for Audio Networks
The RME 12Mic-D features twelve microphone and line level inputs with digital, no-compromise, studio-quality conversion; remote controllable gains; integrated MADI and Dante connectivity; plus a multitude of additional functionality, designed to make it the perfect companion for any professional recording setup. The 12Mic-D is sonically identical to the already existing 12Mic (with 128 AVB channels) and complements the M-Series lineup of professional network audio solutions.

Twelve transparent mic preamps for exceptional conversion performance
The PAD-free microphone input stages have a 75 dB gain range and accept signals of up to +18 dBu. On the converter side, the 12Mic shines with an outstanding signal-to-noise ratio on all channels. All twelve front-facing XLR connections accept microphone and line level signals, whilst the first four connections also accept TRS connectors, with switchable high impedance (Hi-Z) for instruments.

MADI & ADAT for maximum flexibility
In addition to Dante, the 12Mic-D has two separate MADI ports- with coaxial built into the device as standard, and optical MADI available via an optional SFP module - along with three ADAT outputs and a line level headphone output for monitoring all incoming digital and analog signals. With the help of a routing matrix, any of the 12Mic-D’s 204 input channels can be individually routed to any of the 218 output channels.

When connected to a Dante network, a combination of both analog and digital channels (such as connected MADI devices) can be transmitted to the network if required. In return, the 12Mic-D can receive up to 64 audio channels from the Dante network, which in turn can be forwarded to the headphones, ADAT, and two MADI connections as required.

Dante Audio Networking - 2 fully redundant network ports
With an ever changing landscape of network audio solutions, the challenge for RME’s development team was to design a highly performant device platform that will guarantee unparalleled flexibility and stability for years to come. To match these high requirements in accordance with RME’s core principles everything was built from the ground up. By integrating Audinate’s Dante IP Core on a custom built RME FPGA platform, RME is not only delivering a highly flexible solution but also gets one step closer to achieving a truly universal Audio Networking experience.

Plug & play - rapid user interaction
Control all device states directly from the front panel for convenient, direct access to all features. RME network audio devices can also be fully remote controlled via a web-interface on any network link (including wirelessly over Wi-Fi), allowing for the rapid creation of gain groups, phantom power switching, and routing of signals to headphones for monitoring. The integrated routing matrix allows for quick routing of any analog inputs straight to the headphone output, as well as all digital signals. As such, problem-solving of signals, clocking, connectivity or other issues is both simple and straight-forward!
