Page 6: Introduction
Although the Micstasy breaks into a price category which is quite unusual for an RME product, it still offers the typical, outstanding price/performance ratio known from RME. Micstasy's features will excite you – but even more the performance and smartness that it shows in solving any given task. -

After pressing the RECALL button, selecting a preset with the rotary encoder and pressing RECALL a second time, the selected preset is loaded and the state of the channels is updated. In the CLOCK SECTION the current clock reference and frequency multiplier is chosen. User’s Guide Micstasy © RME... - Page 8 Micstasy operate in the range of 100V to 240V AC. It is short- circuit-proof, has an integrated line-filter, is fully regulated against voltage fluctuations, and sup- presses mains interference.

The front input INST/LINE has an input impedance of 5.6 kOhm. Connecting passive instru- ments like bass and guitar, an activation of HI Z changes the input impedance to 470 kOhm, providing perfect conditions for these types of signal sources. User’s Guide Micstasy © RME... -

Save and Recall by pushing these buttons, ANY setup process can be exited immediately by a quick double-push on either Save or Recall. Also it is not necessary to wait 6 seconds until the flashing stops or the setup menu is exited automatically – just do the double-push. User’s Guide Micstasy © RME... -

In Double Speed the delay is 18, in Quad Speed 12 samples. The in most cases slightly increased delay is outweighed by the big advan- tage of sample-aligned I/Os when using multiple units. User’s Guide Micstasy © RME... -

As soon as the current value is met, AutoSet starts to reduce the Gain. This way a headroom equalling the threshold value is created, because the level can not be higher than the current value. User’s Guide Micstasy © RME... -

AutoSet will light up. The only way to determine whether channels are linked or not is to open the Setup menu. Even when Downlink is activated, the values determined by AutoSet can be changed manually without changing relative levels. To do so, all linked channels must be selected when changing gain.

S/MUX method the device else can not know which of the incoming 2 (DS) or 4 (QS) word clock edges is the right one. * With the Micstasy this limitation is also valid for the AES output, as the device internally handles all the data streams in S/MUX mode. User’s Guide Micstasy © RME... -

Page 25: Remote Control
But what about MIDI? Be it remote control commands or sequencer data, in practice only a single MADI line will not suffice. Daher entwickelte RME die MIDI over MADI Technolo- gie. The data at the MIDI input are being included into the MADI signal invisibly, and can be collected at the MIDI output of another Micstasy, ADI-6432, ADI-642, ADI-648, ADI-8 QS or a HDSP MADI, at the other end of the MADI line. -

– distortion, frequency response and signal to noise ratio do not change, or rather exactly like the analog overall gain. Set to +13 dBu and +19 dBu the Micstasy is fully compatible to all RME devices having +4 dBu and Lo Gain as input reference. -

2 channels per AES wire. The effective sample frequency equals the clock on the AES wire. In case a conversion from/to Single, Double and Quad Wire is required, the RME ADI-192 DD, an 8-channel universal sample rate and format converter, is highly recommended. -
Page 33: Adat Optical
ADAT outputs is only half the frequency of the AES outputs. As interesting as this is – you don't need to think about it. 96 kHz capable ADAT hardware, like all current RME digital interfaces, re-combine the data automatically. The user (and the DAW software) does not see any split data, but just single channels at the expected double sample rate. -
Page 34: I64 Madi Card
The problem of this offset is solved by the function Delay Compensation, see chapter 11.3. It delays the signals in a way that they are sample-synchronous in multi-device operation. The diagram on the next page shows a serial setup with HDSP MADI card, three Micstasy and acti- vated Delay Compensation. User’s Guide Micstasy © RME... -

Page 36: Word Clock
As soon as a valid signal is detected, the WCK LED is constantly lit, oth- erwise it is flashing. Thanks to RME's Signal Adaptation Circuit, the word clock input still works correctly even with heavily mis-shaped, dc-prone, too small or overshoot-prone signals. Thanks to automatic signal centering, 300 mV (0.3V) input level is sufficient in principle. -

22 MHz from a slow word clock of 44.1 kHz is no problem anymore. Additionally, jitter on the input signal is highly rejected, so that even in real world usage the re-gained clock signal is of highest quality. User’s Guide Micstasy © RME... -

The Quad Wire method allows to transmit two channels at up to 192 kHz via ADAT. The method is referred to as S/MUX4. Note: All conversions of the described methods are lossless. The existing samples are just spread or re-united between the channels. User’s Guide Micstasy © RME... -

SMPTE (+24 dBu @ 0 dBFS, +4 dBu with 20 dB of headroom). The above levels are also found in our ADI-8 series of AD/DA converters, the Multiface, Fire- face, and even in our Mic-Preamps QuadMic and OctaMic. Therefore all RME devices are fully compatible to each other. -
Page 49: Latency And Monitoring
18.4 Latency and Monitoring The term Zero Latency Monitoring has been introduced by RME in 1998 for the DIGI96 series and describes the ability to pass-through the computer's input signal at the interface directly to the output. Since then, the idea behind has become one of the most important features of mod- ern hard disk recording. -
Page 50: Ds - Double Speed
An implementation of the ADAT format as double S/MUX (S/MUX4) results in only two channels per optical output. Therefore in Quad Speed mode the Micstasy is limited to 4 chan- nels at the ADAT outputs. The AES outputs provide 192 kHz as Single Wire only. User’s Guide Micstasy © RME... -

The table shows that a Professional-coded signal would lead to malfunctions for copy prohibi- tion and emphasis, if being read as Consumer-coded data. Nowadays many devices with SPDIF input can handle Professional subcode. Devices with AES3 input almost always accept Consumer SPDIF (passive cable adapter required). User’s Guide Micstasy © RME... -
Page 52: Signal To Noise Ratio In Ds- / Qs-Operation
When limiting the measurement's frequency range to 22 kHz (audio bandpass, weighted) the value would be -115 dB again. This can be verified even with RME's Windows tool DIGICheck. Although a dBA weighted value does not include such a strong bandwidth limitation as audio bandpass does, the displayed value of –107 dBFS is nearly identical to the one at 48 kHz. -

2 km. Single mode allows for much longer distances, but it uses a completely different fibre (8 µm). By the way, due to the wave-length of the light being used (1300 nm), the opti- cal signal is invisible to the human eye. User’s Guide Micstasy © RME... -
