7.11.3.2 AES3 Input Termination
MENU > I/O CONFIG > AES TERM
Figure 7-14: AES Termination Edit Screen
To adjust the AES3 Input Termination, select AES TERM from the Input Config menu then use the rotary
encoder to toggle the value. An icon is displayed in the bottom left of the display in Meter Mode when AES
is set to ‘Terminated’.
For fault-free operation when using AES3 digital audio as an input source, inputs must be correctly termi-
nated with the characteristic impedance of 110 ohm. The Input Termination setting is determined by the
method used to distribute the AES3 signals.
The processor at the end of a distribution line should be set to TERMINATED; all other processors should
be set to UNTERMINATED. If an AES3 distribution amplifier (DA) is being used to distribute the digital audio
signals, with one DA output per processor, then all terminations should be on. However, if the AES3 is
daisy-chained, only terminate the last processor in the chain.
