Page 4: Adc Modul
A matching connec- tion cable (power jack to terminals 6.3 mm) is available from RME. A Panasonic LC- R122R2PG battery, 12 V 2.2 Ah, can operate the OctaMic for 2 hours. -
Page 5: Operation And Usage
LINE LEVEL OUTPUTS: 8 TRS (stereo) jacks. The electronic output stage is built in a servo balanced design, handling monaural (unbalanced) and stereo jacks (balanced) correctly. AUX: Connect power supply, lead-battery or battery. See chapter 5, Power Supply. User's Guide OctaMic © RME... -

The same is true and even more efficient at –10 dBV. In this case the output level is reduced by around 14 dB – the same happens to the basic noise of the unit! User's Guide OctaMic © RME... -

5 has to be set to the lower position. The OctaMic will now generate an output signal in the Quad speed range (176.4 or 192 kHz), even with a word clock input signal of only 44.1 kHz, or an AES input signal signal of 96 kHz. User's Guide OctaMic © RME... -

Another push will release it again and de-activate the termination. 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 are sufficient in principle. -
Page 9: Digital Outputs
Note that most consumer-orientated equipment (with optical or phono SPDIF inputs) will only accept signals in ‘Consumer’ format! The status 'Professional' should always be active when sending data to a device with AES/EBU input (when XLR connectors are used). User's Guide OctaMic © RME... -
Page 10: 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 11: Word Clock
No wonder Superclock did not become a commonly accepted standard. The actual end of these problems is offered by RME's SteadyClock technology. Combining the advantages of modern and fastest digital technology with analog filter techniques, re-gaining a low jitter clock signal of 11 MHz from a slow word clock of 44.1 kHz is no problem anymore. -
Page 12: Cabling And Termination
Connect the free end to the next device in the chain via a further BNC cable. The last device in the chain should be terminated using another T-adapter and a 75 Ohm resistor (available as short BNC plug). Of course devices with internal termination do not need T-adaptor and termi- nator plug. User's Guide OctaMic © RME... -
Page 13: Technical Background
Devices using this method are not known to us, so we decided to do without this format. The AES outputs provide 192 kHz as Single Wire only. This is forced by the space not avail- able for further D-sub connectors, necessary for Double Wire (Quad Wire...) implementation. User's Guide OctaMic © RME... -
Page 14: Aes/Ebu - Spdif
Nowadays many devices with SPDIF input can handle Professional subcode. Devices with AES3 input almost always accept Consumer SPDIF (passive cable adapter necessary). User's Guide OctaMic © RME... -
