When connecting digital unbalanced ADS3-ID 75 audio signals to a digital unbalanced board, the following wir-
ing can be used:
Three wire digital unbalanced connection
•
Connect the hot output of the source via the hot wire of the cable to v+ of the EDAC connector!
•
Connect the ground/shield of the source to the ground/shield of the cable!
•
Connect the ground/shield of the source to the v- of the cable!
•
Connect v- of the cable with the GND of the EDAC connector!
•
v- of the EDAC connector is not connected!
Two wire digital unbalanced connection
•
Connect the hot output of the source via the hot wire of the cable to v+ of the EDAC connector!
•
Connect ground/shield of the source via the ground/shield of the cable to the GND of the EDAC connector!
•
v- of the EDAC connector is not connected!
When connecting digital balanced ADS3 110 audio signals to a digital balanced board, the following wiring can
be used:
Three wire digital balanced connection
•
Connect the hot output of the source via the hot wire of the cable to v+ of the EDAC connector!
•
Connect the cold output of the source via the cold wire of the cable to v- of the EDAC connector!
•
Connect the ground/shield of the source via the ground/shield of the cable to the GND of the EDAC connec-
tor!
It is recommended to only connect suitable digital audio signals to the digital audio boards,
i.e. a balanced digital audio signal to a digital balanced audio board or an unbalanced
digital audio signal to an unbalanced digital audio board.
If the signal is not suitable an impedance matching transformer should be used first to
convert the signal to a suitable standard!
