8. Operation and Usage
8.1 External Connections
HDSP 9652 consists of the main PCI board and an Expansion Board. All the essential
electronics are located on the PCI card, so it will also work without the Expansion Board.
The main board's
bracket has two
ADAT optical
inputs and two
ADAT optical
outputs, as well
as a 9-pin D-type
socket. Coaxial
S/PDIF input and
output requires
plugging in the
adapter cable, whereby the red phono socket is the output. The ADAT1 I/O next to the D-type
socket can also be used for optical SPDIF, if this mode is selected in the Settings dialog.
An input is selected via the Settings dialog (started by clicking on the hammer symbol in the
system tray). Hammerfall accepts the commonly used digital audio formats, SPDIF as well as
AES/EBU. Channel status and copy protection are ignored.
In SPDIF mode, identical signals are available at both the optical and the coaxial outputs. An
obvious use for this would be simply connecting two devices, i.e. using the HDSP 9652
as a splitter.
To receive signals in AES/EBU
format, an adapter cable is
required. Pins 2 and 3 of a female
XLR plug are connected
individually 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 using transformers for digital inputs and outputs enables trouble-free
connection to all devices, and perfect hum rejection.
The Expansion
Board's bracket gives
access to a third
ADAT optical input
and output as well as
word clock I/O. Next
to the two BNC
sockets is an LED,
which displays the
word clock input lock
status. The included breakout cable is connected to the 9-pin Mini-DIN connector and realizes
two MIDI inputs and outputs.
