he Micstasy is an 8-channel hi-end mic/line/instrument preamp and AD converter combining typical
RME features with a number of previously unseen features. Along with SteadyClock, the Micstasy not
only offers low latency AD conversion of the highest quality, but is also fully remote-controllable via
MIDI and also MIDI over MADI.
Universal input device. The Micstasy’s innovative concept allows for amplification and digitization of all
analog signal sources, including high level stage signals, typical studio signals, lower level and high-impedance
instruments, or dynamic, condenser or ribbon microphones. The impressive 85 dB gain range, digitally
controlled in steps of 0.5 dB, allows connection of all conventional analog studio signals within a range of -56
dBu up to +30 dBu. The analog outputs can be set to a max. level of +27 dBu. The amplified signals are also
available at the analog outputs for passing them on, making an expensive splitter box on stage obsolete. The
Micstasy can be used analog (Mic/Line In to Line Out) and digital (Mic/Line In to Digital Out), with both signal
paths operating simultaneously. The options, Phantom Power (+48 V), Phase, Lo Cut, M/S-encoding (digital
only), Input Selection, Hi-Z and AutoSet can be switched for each channel individually.
Low Latency. The Micstasy uses high-class AD converters, offering exceptional Signal to Noise and distortion
figures. An 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.
Technologies. The Micstasy offers numerous extraordinary features. SyncCheck ensures 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. RME’s SteadyClock 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 prestine sound quality! Additionally Intelligent Clock Control will retain the last valid
sample frequency in case of a loss of the input signal.
Remote Control. One of Micstasy’s outstanding features is its full remote controllability. All functions can be
controlled via MIDI or MIDI over MADI, allowing the device to be placed anywhere on stage or in the studio
– with full control from the studio or FOH mixer. This means that microphone cables can be relatively short,
ensuring high quality signals without interference.

Autoset. Some preamps feature limiters in order to prevent an overload,
especially of the AD converter. This is not feasible for the Micstasy,
as such a limiter would ruin the excellent technical specifications of
the microphone front end. 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.
And the gain can still be changed manually.
Example: In an orchestral recording session, the user sets all channels to
60 dB gain and asks the conductor to let the orchestra play fortissimo.
AutoSet will automatically adjust the levels by reducing the gain. In
AutoSet mode a “threshold” can be set to define an overhead of -1, -3,
-6, or -12dB. Additionally, a special downlink function allows to group
channels for AutoSet mode (e.g. for Stereo- or Surround-Microphone
systems). Manual gain adjustment thus becomes obsolete most of the
time.
MADI. The I64 MADI Card provides the Micstasy 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. The
I64 MADI Card features an optical as well as a coaxial MADI input and
provides serial pass-through capability from one Micstasy to the next
(up to 8). Such a way of cascading is also possible between Micstasy
and other RME MADI devices, like the ADI-8 QS.
Furthermore the I64 MADI Card provides the ability of 8 channels being
used as digital return path, sending audio via MADI to the Micstasy’s
ADAT and AES outputs. For example stage and studio monitors can be
fed digitally from the Micstasy. On stage the use of an additional D/A-
converter (e. g. ADI-8 DS) might be necessary.
