Overview: |
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.

Features: |
In a
standard 19"
box with 2
unit height
the device
offers
numerous
extraordinary
features
like
Intelligent
Clock
Control
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.

Low Latency: |
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.

Optional i64 MADI Card: |
The I64 MADI Card provides the
Micstasy with a 64-channel MADI input
and output. Coaxial and 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. The input
is switched automatically, according to
where a valid input signal is detected. Full
redundancy is ensured by the automatic input
switching, immediately changing to the other
input in case of loss of the input signal.
The MADI input will operate as an optional
clock source (Clock section, OPTN) as well
as a thru-input. Since each Micstasy uses
only 8 channels, up to 56 channels can be
passed through. This technique is used to
serially cascade several Micstasys. Incoming
MADI data is passed through unchanged, only
one block of eight channels is replaced.
This allows up to 8 devices to be connected
serially. All 64 combined channels are
available at the last device's MADI output.
With an installed I64 MADI Card the
Micstasy can be remote controlled via
MADI. At the same time MIDI data are
transmitted via MADI.
When multiple devices are connected
serially, the MADI I/O of each Micstasy
causes a delay of 3 samples. Therefore
at the MADI output of the last device, the
data of all upstreamed devices are delayed.
The problem of this offset is solved by the
function Delay Compensation.
Using 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. The MADI
output continues to carry the analog input
signals and the fed-through input data.
