ADX-32A / ADX-64A-PRO

Output (DIP switch in upper position = ON) : The ADAT connection is configured as output (the
sender is active). Data received from the Cat5 cable is output on the “Output” jack.
Within a system, for each ADAT connection there must be only one sender (input) device.
8.3. Transmission direction (ADAT 5-8), ADX-64A-PRO only
The transmission direction (input or output) for ADAT connections 5-8 and the wordclock signal
is set by the DIP-switches 1-4.
8.4. Channel 5 mode selection (ADAT or Wordclock)
The mode of operation of channel 5 is user selecteable.

ADAT transmission: Set DIP switch #6 to “ON”. The direction can be set with DIP switch #1
(Output=“ON” , Input=“OFF”). The BNC wordclock jack is now disabled.

Wordclock transmission : Set DIP switch #6 to “OFF“. The direction of the wordclock
transmission can then be set with DIP switch #1 (Output=“ON”, Input=“OFF”).
ADAT Connection 5 is now disabled.
8.5. Wordclock termination
For proper operation, it is important to set the wordclock termination using DIP switch
#5 accordingly. (Do not confuse with Cat5 termination, switchable on the front side).
An ADAT Multicore Extender connected to the end of the wordclock coaxial cable
must have set the termination to ON (DIP switch #5=ON). If it is connected in the
middle of a coaxial cable (using a T-type connector), the wordclock termination must
be set to “OFF”.
NOTE: We recommend connecting the ADAT Multicore Extender on the end of the wordclock
cable (without T-type connector) with the termination set as follows:

At the input side (where the wordclock source – mixer, reference clock etc. - is connected, the
termination must be “ON”.

At the output side (where wordclock slaves, like DACs, ADCs, Recorders etc.) are connected,
the termination should be “OFF”. At the other end of the cable, a termination must be installed
by means of either a T-type connector with a 75 ohms resistor attached, or by switching on a
termination resistor within the device. There are different possibilities depending on the used
device, please refer to the manual of the respecting device for instructions.
