RME 12Mic 12-Channel Mic Preamp with AVB and MADI

The RME 12Mic is a 12-channel mic preamp with remote-controlled gain, AVB networking, MADI, and three ADAT outputs, built into a 1U rack unit.

Twelve Mic Preamps

All twelve front XLR inputs take microphone or line signals, with 75 dB of gain in 1 dB steps and no pad, and accept up to +18 dBu. Inputs 1 to 4 also take TRS jacks, switchable to high impedance for instruments, and 48 V phantom power switches on for each XLR input.

AVB Networking

Two Gigabit Ethernet ports provide fully redundant AVB networking to the MILAN recommendations, with eight streams of up to 16 channels each in each direction. Any AVB controller can find and control the 12Mic, and streams run with fixed latency and reserved bandwidth, with no switch configuration needed.

MADI and ADAT

Coaxial MADI is built in, and an optional SFP module adds optical MADI, for independent or redundant use, daisy chaining, and merging MADI signals. Three ADAT outputs send up to 24 channels at 48 kHz or 12 at 96 kHz from any mix of mic inputs, MADI, and AVB signals. They can also feed monitor mixes to existing converters or headphone amps.

Control, Clock, and Power

A color display, a control knob, four buttons, and a button on each channel reach every setting on the front panel. A web interface on any network link, Wi-Fi included, sets gain groups, phantom power, and headphone routing, and the routing matrix sends any analog input or digital signal to the headphone output.

SteadyClock FS keeps jitter low and rejects jitter from external clocks, and Intelligent Clock Control handles changes of clock source. An internal 100 to 240 V AC supply powers the 12Mic, and an optional external 12 V DC supply adds power redundancy.
