AES/EBU Sync
The input AES 1 (channel 1/2) found on the D-sub connector can not be used for audio with the
OctaMic II, but as clock source. The input is transformer-balanced and ground-free. Thanks to a
highly sensitive input stage, a SPDIF signal can also be fed by using a simple cable adapter
phono/XLR (see above).

11.2 ADAT Optical
The OctaMic II provides two digital outputs in ADAT optical format. In Single Speed mode both
outputs carry the same audio data. With this it is possible to distribute the output signal to two
devices (2 x ADAT splitter).
As the ADAT optical signal is physically specified up to 48 kHz only, the OctaMic II automatically
activates Sample Split mode (S/MUX) at 88.2 and 96 kHz, distributing the data of one channel to
two output channels. The internal frequency stays at 44.1/48 kHz. Therefore the sample clock at
the 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.
Up to 96 kHz (Double Speed), the ADAT outputs can be used in parallel to the AES outputs. In
Quad Speed mode (128 kHz up to 192 kHz), the ADAT outputs are operated synchronously at
Single Speed sample clock, but do not provide any audio data.
The ADAT optical outputs of the ADC Module are fully compatible to all ADAT optical inputs. A
usual TOSLINK cable is sufficient for connection.
ADAT Main
Interface for the first or only device receiving an ADAT signal from the OctaMic. Carries the chan-
nels 1 to 8. When sending a Double Speed signal, this port carries the channels 1 to 4. In Quad
Speed mode ADAT MAIN carries an empty but synchronous ADAT signal.
ADAT AUX
Copy of the data at the MAIN output. When sending a Double Speed signal, this port carries the
channels 5 to 8. In Quad Speed mode ADAT AUX carries an empty but synchronous ADAT signal.
