RME 12Mic 12-Channel Networked Mic Preamp with AD Conversion, AVB & MADI

RME 12Mic: Twelve Reference Preamps and Networked Conversion in One Rack Space

The RME 12Mic is a digitally controlled 12-channel microphone preamp and analog-to-digital converter with built-in AVB and MADI network audio, packaged in a single 1U 19-inch rack. It combines twelve PAD-free preamps, reference conversion rated at 121.2 dB(A), and redundant MILAN-based networking so an entire stagebox lives in one chassis. For the engineer who has spent years wrangling separate preamps, converters, and network bridges, the 12Mic folds that whole signal chain into a device you configure once and trust for a decade. It is the kind of front end that quietly disappears into a rig and simply captures every source cleanly, take after take.

Twelve PAD-Free Preamps With 75 dB of Digitally Controlled Gain

Each of the twelve microphone preamps offers a 75 dB gain range set in fine digital steps, and because the design is PAD-free it accepts sources as hot as +18 dBu without an attenuation pad muddying the path. A PAD-free preamp means the gain stage handles both a whisper-quiet ribbon microphone and a screaming close-miked snare on the same channel, with no switch to flip and no tonal penalty. Channels 1-4 sit on XLR/TRS combo jacks that switch to Hi-Z, so a bass or guitar plugs straight into the front. In multi-microphone orchestral or broadcast work, having a dozen identically clean, remotely settable preamps means the whole array behaves as one predictable instrument.

Reference AD Conversion at 121.2 dB(A) and 192 kHz

Conversion quality is measured in signal-to-noise ratio, and the 12Mic posts 121.2 dB(A) on all twelve channels at resolutions up to 192 kHz and 24-bit. That figure describes how far the loudest signal sits above the converter's own noise floor, so more dynamic range means quiet passages stay detailed and loud transients never crowd the ceiling. RME builds the AD stage to be transparent rather than flattering, capturing exactly what the microphone hears. When those channels feed a mastering-grade recording or a broadcast feed, the conversion adds nothing of its own and takes nothing away.

Redundant AVB Networking Built on the MILAN Standard

The 12Mic carries its audio over Audio Video Bridging (AVB), an open IEEE networking standard, using the MILAN profile that guarantees interoperability between certified pro-audio devices. Two RJ45 network ports provide automatic redundancy: if one cable or switch fails, audio keeps flowing on the second path with no dropout. AVB reserves guaranteed bandwidth and timing on the network, which is why it is trusted for live shows and installations where a glitch is not an option. A theater or arena can run dozens of channels from stage to console over standard Ethernet cabling and know the link will hold.

Coaxial and Optical MADI Plus Three ADAT Outputs

Beyond the network, the 12Mic offers coaxial BNC MADI and optical MADI through an SFP cage, so it drops directly into an existing MADI backbone. MADI (the AES10 multichannel standard) moves up to 64 channels down a single cable, which is why large studios and broadcast trucks have relied on it for decades. Three optical ADAT outputs add another 24 channels of lightpipe connectivity for feeding older interfaces and converters. Between AVB, MADI, and ADAT, the unit speaks to nearly any digital system it might be dropped into, present or legacy.

SteadyClock FS Keeps the Whole System in Time

Every digital converter depends on its clock, and jitter, the tiny timing errors between samples, smears stereo imaging and dulls high-frequency detail. RME's SteadyClock FS is a femtosecond-class clock that regenerates a clean, low-jitter reference even from a noisy incoming signal, while SyncCheck continuously verifies that all sources are locked. In a networked rig with many devices, one stable clock keeps every converter sample-accurate and phase-coherent. The result is that a 12-microphone capture stays tight and focused rather than washy, no matter how large the system grows around it.

Complete Remote Control From the Rack or the Network

A color TFT display and rotary control on the front panel expose every parameter without a computer, so an engineer can set gain, phantom power, and routing right at the rack. The same controls are mirrored in a browser-based web remote and are reachable from any standard AVB controller, meaning a monitor engineer at front-of-house can adjust a stagebox 200 feet away. Because the preamps are digitally controlled, settings recall exactly and travel with the session. For touring and broadcast crews, that repeatability turns a complicated multi-channel setup into a saved snapshot.

Who the 12Mic Is For

The 12Mic suits the broadcast and live-sound engineer who needs a reference-grade networked stagebox, the theater or house-of-worship installer standardizing on AVB, and the classical or orchestral recordist capturing a dozen microphones at once. Its redundant networking and remote control matter most where downtime is unacceptable and the console is far from the stage. If you want twelve pristine preamps, transparent conversion, and flexible MADI and AVB connectivity in a single rack space, the 12Mic is the front end an entire system can be built around.
