RME 12Mic Digital Mic Preamp

RME’s 12Mic is a 12-channel remote controllable mic preamp with no-compromise A/D conversion, integrated AVB and MADI connectivity, and a multitude of features.

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.

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.
