Use the supplied cable to connect the AES/EBU Inputs/
Outputs.
Cable type is twisted pair (12 pairs) with common screen.
Recommended impedance: 110 Ohm.

Sync In Word Clock
ForconnectionstoexternalclockviathestandardBNC
connector (see illustration above).
When several devices are connected in a chain and
synced via Word Clock, termination on the last device of
the chain is necessary.
As the System 6000 is expected to be the last unit in such
a chain (or the only), the factory default setting on the
System 6000 DSP card is: TERMINATED (75 Ohm).
If you need to terminate the Word Clock signal elsewhere
in the chain you will need to un-terminate the System 6000
DSP card. To do this you must remove the DSP card from
the mainframe and remove the termination jumper:
• Switchoffthepoweranddisconnectmainpowercord.
• LoosenthetwoscrewsholdingtheDSPcardand 
remove the card gently.
• RemovetheterminatingjumperneartheBNCplug.
• InsertthecardgentlyintheDSPslotandremount
the screws.
Pins connected via jumper : Terminated (75 Ohm).
Pins NOT connected via jumper : Not Terminated

General Handling
When inserting or removing any modules, avoid touching
the circuit board by handling only the rear panel of the
module. To minimize the static potentials that can cause
damage to the electronic circuits, you should observe
precautionary grounding techniques such as touching a
grounded System 6000 Mainframe immediately before
inserting modules.
