29. Digital Connections
29.1 ADAT
The ADAT optical input of the Fireface 400 is fully compatible with all ADAT optical outputs.
RME's unsurpassed Bitclock PLL prevents clicks and drop outs even in extreme varipitch op-
eration, and guarantees a fast and low jitter lock to the digital input signal. A usual TOSLINK
cable is sufficient for connection. More information on Double Speed (S/MUX) can be found in
chapter 37.5.
ADAT In
Interface for a device sending an ADAT signal to the Fireface 400. Carries the channels 1 to 8.
When receiving a Double Speed signal, this input carries the channels 1 to 4.
ADAT Out
Interface for a device receiving an ADAT signal from the Fireface 400. Transmits channels 1 to
8. When sending a Double Speed signal, this port carries channels 1 to 4.
29.2 SPDIF
The SPDIF input is configured in the Settings dialog, available by a click on the fire symbol in
the Task Bar's system tray. The Fireface 400 accepts all commonly used digital sources as well
as SPDIF and AES/EBU. Channel status and copy protection are ignored.
To receive signals in AES/EBU format, an
adapter cable is required. Pins 2 and 3 of
a female XLR plug are connected indi-
vidually to the two pins of a phono plug.
The cable shielding is only connected to
pin 1 of the XLR - not to the phono plug.
The ground-free design, with transformers for coaxial digital inputs and outputs, offers a trouble-
free connection of all devices along with perfect hum rejection and full AES/EBU compatibility.
In SPDIF mode, identical signals are available at both the optical and the coaxial output. An
obvious use for this would be to connect two devices, i.e. using the Fireface 400 as a splitter
(distribution 1 on 2).
