9.8 Digital Connections
ADAT
The ADAT optical input of the Babyface is fully compatible with all ADAT optical outputs. RME's
unsurpassed Bitclock PLL prevents clicks and drop outs even in extreme varipitch operation,
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
26.4.
ADAT In
Interface for a device sending an ADAT signal to the Babyface. Carries the channels 1 to 8.
When receiving a Double Speed signal, this input carries the channels 1 to 4, at Quad Speed
the inputs 1 and 2.
ADAT Out
Interface for a device receiving an ADAT signal from the Babyface. Transmits channels 1 to 8.
When sending a Double Speed signal, this port carries channels 1 to 4, at Quad Speed the
channels 1 and 2.
Note
: To use the optical output as ADAT port set the option Optical to ADAT in the Settings
dialog.
SPDIF
The optical input automatically switches to SPDIF operation when such a signal is detected.
The audio information is then shown in TotalMix on the first two ADAT channels, AS 1 and AS
2.
Activating the option TMS in the Windows Settings dialog enables RME’s DIGICheck to analyze
the Channel Status of the input signal.
To send out SPDIF from the optical output, select the option Optical – SPDIF in the Settings
dialog. The output signal in TotalMix has to be present on the first ADAT channels, AS 1+2.
MIDI
Babyface offers one MIDI I/O via two 5-pin DIN jacks. The MIDI ports are added to the system
by the driver. Using MIDI capable software, these ports can be accessed under the name Baby-
face Midi. Using more than one Babyface, the operating system adds a consecutive number to
the port name, like Babyface MIDI (2) etc.
The MIDI ports support multi-client operation. A MIDI input signal can be received from several
programs at the same time. Even the MIDI output can be used by multiple programs simultane-
ously. However, due to the limited bandwidth of MIDI, this kind of application will often show
various problems.
