RME 12Mic

The RME 12Mic is a twelve channel remote controllable microphone preamplifier with no-compromise A/D conversion, integrated AVB and MADI connectivity, and a multitude of features designed to make it a perfect companion for any professional recording.

Designed for the Next Decade - RME’s first preamp for Audio Networks

The RME 12Mic features twelve microphone and line level inputs with digital, no-compromise, studio-quality conversion; remote controllable gains; integrated MADI and AVB connectivity; plus a multitude of additional functionality, designed to make it the perfect companion for any professional recording setup.

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

Both coaxial and optical (via an SFP module) MADI I/O is available for independent or redundant operation, and can be used for daisy chaining, merging and converting MADI signals at incredibly low latency. Three optical ADAT outputs provide up to 24 channels of audio at single speed (for example, a combination of microphone inputs, MADI signals and AVB signals), or 12 output channels at 96 kHz sampling rate, ensuring compatibility with a wide range of audio interfaces. Additionally, the ADAT ports can also be used to send monitor mixes from the AVB or MADI inputs to existing DACs/headphone amps.

AVB Audio Networking - 2 fully redundant network ports

For the first time, RME offers an AVB device with two fully redundant network ports, based on the recommendations of MILAN. The RME AVB Core has meticulously implemented the IEEE standards for audio- streaming, discovery and control, allowing RME devices to be both discovered and fully controlled by any AVB controller, and making vendor-specific control protocols a thing of the past. Any signal reaching the 12Mic can be routed and streamed over a network with fixed latency and guaranteed bandwidth - no switch configuration is required!

Plug & play - rapid user interaction

Control all device states directly from the front panel for convenient, direct access to all features. RME AVB 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 and AVB streams. As such, problem-solving of signals, clocking, connectivity or other issues is both simple and straight-forward!

SteadyClock FS - Reference class Digital Clocking

In digital audio, the clock frequency is an essential factor, as it creates the correlation between the audio bits and the time reference. Unfortunately, the clock frequency is not always as stable as desired. The 12Mic offers full SteadyClock FS performance for lowest jitter and highest jitter immunity.

Excellent performance in all clock modes and High Quality Analog Conversion to hear your mix as it is. Digital format conversion in RME products are done without any loss or degradation, and SteadyClock FS ensures your sonic image will never experience degredation. This helps to optimize recordings and mixes because the soundstage has more depth and clarity.
