Operation as second AES/EBU I/O
Receiving signals in AES/EBU format requires a cable adapter. Pins 2 and 3 of a female XLR
plug are connected individually to the two pins of a RCA plug. The cable shielding is only con-
nected to pin 1 of the XLR - not to the RCA plug (see chapter 18.2).
Professional AES/EBU equipment can be connected to the HDSPe AIO thanks to the ‘Profes-
sional’ format option with doubled output voltage. The required cable is the same as the one for
the input, but with a male XLR plug instead of a female one.

18.4 MIDI
The HDSPe RayDAT offers two MIDI I/O via 5-pin DIN connectors. The MIDI ports are added to
the system by the driver. Using MIDI capable software, these ports can be accessed under the
name
RayDAT MIDI
. Using more than one HDSPe RayDAT, a consecutive number is added to
the port name, like
RayDAT MIDI In 1 (2)
etc.
19. Word Clock
19.1 Word Clock Option
With the HDSPe RayDAT the usage of word clock is usually unnecessary - the card can extract
its clock perfectly from the digital input signals. Due to SteadyClock’s highly efficient jitter sup-
pression the HDSPe series refreshes and cleans up any clock signal, and provides it as refer-
ence clock at all the digital outputs (see chapter 27.6). Therefore word clock I/O is only available
via the optional WCM Expansion Board. Its word clock input can be set to high-impedance or
terminated (75 Ohms) by pushing the switch on the slot bracket.
Thanks to a low impedance, but short circuit proof output, the WCM delivers 4 Vpp to 75 Ohms.
For wrong termination with 2 x 75 Ohms (37.5 Ohms), there are still 3.3 Vpp at the output.
Selecting
Single Speed
in the Settings dialog causes the output signal to always stay within the
range of 32 kHz to 48 kHz. So at 96 kHz sample rate, the output word clock is 48 kHz.
