5. First Usage
5.1 Quick Start
The user interface of the ADI-4 DD is characterized by a clearly structured architecture and an
unambiguous labelling of the front and rear sides. The device can thus be used easily without a
manual, because numerous LEDs show the state of the device and of all incoming and outgoing
signals in a strictly logical way.
After connection of the power supply, all LEDs on the front panel will be lit for a short time. Next
the current firmware revision is displayed on the INPUT STATE display for about a second. At
the time of writing version 1.1 was the latest one, so the LEDs AES1 Level and Sync are lit.
Then the settings are loaded and the unit is ready to be used.
After connection of one (or more) digital sources, the ADI-4 DD can be configured quickly via
the 4 buttons on the front panel:
•
AES 1
: Determines the current AES 1 input. Options are the
XLR
socket on the rear, the 25
pin
D-Sub
connector, and the
opti
cal input IN 2.
•
SYNC
: Determines the clock source. Options are
W
ord
C
lock,
ADAT
IN 1 and the input
selected via
AES
1.
•
DS MODE
: Activates Double Speed mode for the
W
ord
C
lock output, for the
AES
outputs, or
for both.
•
AES STATE
: Sets the Channel Status of the AES output signals to
Pro
fessional or
Con-
sumer. With Professional, the physical output voltage is raised too. In combination with
Opt
i-
cal channels 1/2 will be available also at the optical output OUT 2.
The ADI-4 DD remembers all settings before switching off and sets them automatically when
switching on the next time.
A quick guide for operation and functionality of the ADI-4DD can be found on the next page.
For transmission of the digital signals into a computer with PCI-bus, we recommend RME's
interface cards of the Hammerfall
®
DSP Series. These high quality digital audio cards are avail-
able with drivers for all common operating systems, and have the highest reputation world-wide.
