Micstasy is an 8-Channel hi-end mic/line preamp and AD-converter combining typical RME features with a number of previously unseen features. It can be used analog (Mic/Line In to Line Out) and digital (Mic/Line In to Digital Out), with both signal paths operating simultaneously. Special highlight: the device is fully remote-controllable via MIDI (also MIDI over MADI).

The Micstasy’s innovative concept allows for amplification and digitization of ALL analog signal sources. Be it high-level stage signals, typical studio signals, lower level and high-impedance instruments, or dynamic, condenser or ribbon microphones: Micstasy understands them all – in a way that is simply thrilling.

The signals amplified by the Micstasy are available at the analog outputs for passing them on, making an expensive splitter box on stage obsolete. All functions can be remote controlled via MIDI and MIDI over MADI, allowing the device to be placed near the microphones, ensuring highest sound quality. Adding the optional MADI Card results in even more options. The I64 MADI Card provides serial pass-through capability from one Micstasy to the next (up to 8). All up to 64 audio signals are then available at the last device on one single line. Such a way of cascading is also possible between Micstasy and ADI-8 QS.

Micstasy Features

In a standard 19″ box with 2 unit height the device offers numerous extraordinary features like Intelligent Clock Control (ICC) , SyncCheck ®, SteadyClock, TotalGain, AutoSet, MIDI over MADI, and remote control via MADI and MIDI.

The technologies known from other RME products like SyncCheck® ensure perfect synchronization and clear detection of errors. Also multiple units can be stacked and operated sample-aligned, using word clock. All settings are stored when the unit is switched off.

The Micstasy can be fully remote controlled and configured via MIDI, and all status displays can be queried through MIDI. Each Micstasy can be given a separate ID, allowing separate remote controllability of various devices with only one MIDI channel. The MIDI remote is also compatible to Digidesign’s Pro Tools system, Yamaha’s M7C and PM5D. The manual further shows how to remote control the Micstasy from the DM-1000 and DM-2000.

RME’s SteadyClock(TM) guarantees excellent clock quality in any situation. Due to the highly efficient jitter reduction, the Micstasy’s AD-converters operate independently from the quality of the external clock signal, as if they are working with internal clock all the time – guaranteeing a pristine sound quality! Additionally Intelligent Clock Control (ICC) will retain the last valid sample frequency in case of a loss of the input signal.

In the Micstasy RME uses high-class AD-converters from Cirrus Logic, offering exceptional Signal to Noise and distortion figures. But the biggest difference to all other ADCs out there is its innovative digital filter, achieving for the first time a delay of only 12 samples in Single Speed 0.25 ms), 9 samples in Double Speed 0.09 ms), and 5 (!) samples in Quad Speed (0.026 ms).

These values are less than a quarter of those available from even much more expensive devices. They represent an important step in further reducing the latency in the computer-based recording studio. At DS and QS the added latency can simply be ignored. And with the ADI-8 QS, a matching DA-converter with only 5 up to 10 samples delay will turn ‘analog digital monitoring’ into real analog-style monitoring.

AUTOSET

Some preamps include limiters in order to prevent clipping, especially of the A/D converter stage. Such a circuitry is not feasible for the Micstasy, because it would spoil the mic preamp’s excellent technical specifications.

But as the Micstasy’s gain is controlled completely digitally, the device can set it automatically, thus providing perfect protection from overload with no degradation of the audio signal, which does not have to pass any additional electronic circuitry.

In the Setup menu, the threshold level beyond which the gain will be reduced can be adjusted in four steps (-1, -3, -6, -12 dBFS). Any change of gain will be shown immediately on the GAIN displays. And with AutoSet activated, the gain can still be changed manually.

The I64 MADI Card provides the DMC-842 with a 64-Channel MADI input and output. Coaxial and optical output operate in parallel to the AES/EBU and ADAT output, therefore deliver the same data.
