RME 12Mic-D Network-Ready Microphone Preamp with Dante, ADAT, and MADI

Add 12 channels of pristine mic/line inputs featuring 75 dB of gain to your networked audio system with the 12Mic-D from RME. Designed to conveniently integrate into modern digital workflows, the 1 RU rackmount preamp and analog to digital converter provides two RJ45 ports for Dante networking, three ADAT output, and a pair of coaxial MADI ports with an optical SFP option available.

The 12 mic/line inputs are all on the front panel, with 8 XLR connectors and 4 TRS/XLR connectors that feature Hi-Z switches for instruments. Control the input gain and other settings from the buttons, knob, and color screen on the front panel, via a web interface network link, or wirelessly using Wi-Fi. A 1/4″ jack on the front panel provides quick headphone monitoring.

Any signal can be routed over a network with a fixed latency to ensure steady playback. RME’s SteadyClock FS also ensures precise synchronization among elements, giving you a performance free from jitter, so your audio is as clear as it can be. The unit also features a redundant power supplies. Use the DC input and the IEC VAC input to ensure that accidental disconnection of either won’t cause the 12Mic-D to shut off.
