The input AES 1 to 4 (channel 1-8) found on the D-sub connector can be used for audio (Digital
Routing) but also as clock source. Thanks to a highly sensitive input stage, a SPDIF signal can
also be fed by using a simple cable adapter phono/XLR (see above).

13.2 ADAT Optical
The OctaMic XTC provides two digital outputs in ADAT optical format. In normal operation
these ports carry the converted analog input signal. Via the menu Digital Routing also AES,
USB, MADI and even ADAT can be chosen as source.
In Single Speed mode both outputs can carry the same audio data, when set up accordingly in
Digital Routing. With this it is possible to distribute the output signal to two different devices.
When operating with sample rates higher than 48 kHz the entry ADAT 2 in the menu Digital
Routing will be grayed out. The OctaMic XTC then is in S/MUX mode, and will send the source
signal selected for ADAT 1 also at the ADAT 2 port.
As the ADAT optical signal is physically specified up to 48 kHz only, the OctaMic XTC auto-
matically 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 and 192 kHz capable ADAT hardware, like all
current RME digital interfaces, re-combine the data automatically. The user (and the DAW soft-
ware) does not see any split data, but just single channels at the expected double sample rate.
The ADAT outputs can be used at up to 192 kHz, but in QS mode only channels 1 to 4 will be
available.
The ADAT optical outputs of the OctaMic XTC 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 XTC. Carries
the channels 1 to 8. When sending a Double Speed signal, this port carries the channels 1 to 4.
In Quad Speed mode this port carries channels 1 and 2.
ADAT AUX
In Single Speed mode carries the source signal set for ADAT 2 in Digital Routing. When send-
ing a Double Speed signal, this port carries the channels 5 to 8 of the source signal set for
ADAT 1. In Quad Speed mode this port carries the channels 3 and 4 of the source signal set for
ADAT 1.
