InstallationDigital audioCables for AES/EBU digital audioAES3 species that the nominal characteristic impedance of cables used for AES/EBU digital audio transmissionshall be 110 Ω ± 20%, and closer tolerances allow for increased transmission reliability over long lengths orhigher sampling rates.Therefore, it is highly recommended to use high-quality AES/EBU rated cables only, although certain cablesdesigned for balanced analog audio prove to be acceptable at 48 kHz sampling rate over short distances.It is recommended to use single cuts of cable between AES/EBU outputs and inputs. Using several pieces reducesperformances. If it is not possible to use single cuts, it is required to use the same model of cable between twoAES/EBU interfaces.In case an amplied controller shuts down, the failsafe relay makes a passive connection between the AES/EBU IN port and the LINK port to maintain continuity. However the signals are no longer refreshed for the nextamplied controller, so that the input cable and the link cable must be considered as a unique input cable withregard to the maximum supported length.In case of transmission losses, try to reduce the sampling frequency of the digital audio source. Moreover, as ageneral rule, avoid using sources rated beyond 96 kHz, as the maximum possible cable length is reduced, whilethe additional information is cancelled by SRC to 96 kHz.In a daisy-chain layout, the male XLR link connector feed the input signals to the next amplied controller in the signalchain.Daisy-chaining digital audioAES/EBU INAES/EBU LINKLA8 user manual (EN) version 13.1 26 |
