5. AB8 Back panel
The back panel has the ADAT optical output, BNC connectors for word clock as well as
the selector switches and power cord connector.
5.1 Word Clock Input
Use this BNC connector when running the AB8 from an external clock source (make sure
you select EXT sync)
5.2 44.1 / 48kHz selector switch
Use this switch to select which sample rate the unit will be running at. Please make sure
the equipment connected to the ADAT output of the AB8 matches this sample rate as well.
5.3 Optical ADAT OUTPUT connector
Connect your optical cable (ADAT FORMAT) to this output connector, the ADAT OPTICAL
cable will transfer all 8 channels on this one cable.
5.4 External / Internal selector switch
Use this switch to select INTernal or EXTernal Word Clock sync, when the unit is being
used as a master, use the INT setting. When you want the unit to be a slave device select
EXT. You can easily see if the unit is working properly by looking into the optical output
connector. If you see a RED LIGHT you know the unit is sending out DATA in the selected
mode.
5.5 Word Clock Output
Use this connector if you want to sync other devices using the AB8’s own internal clock.
6. APPLICATION
6.1 Using the AB8 to convert line level signals to ADAT
Make sure the AB8 is powered and that the ADAT signal is running (red light in the optical
output). Connect several devices (Kb’s, mixer, Mp3 players etc) to the AB8.
If you are using a recording interface, make sure you select EXTERNAL ADAT SYNC in
your master clock selection and connect the AB8 to the ADAT input of your interface. For
digital desks you would also select EXTERNAL ADAT CLOCK as your master.
If you have an external recording device which has WORD CLOCK output you could use
the recording device as the master and then connect both a BNC coaxial cable as well
as the optical cable to the AB8. Make sure you select external WORD CLOCK source on
the AB8. Connect the cable from the WORD CLOCK output of the device to the WORD
CLOCK input of the AB8
Adjust the attenuator on each of the inputs so that you do not overload the signal and
cause distortion.
