Checklist
After assembling a networked audio system it is good
practicetoconductasystematicseriesofcheckstomake
sure everything is OK. These checks should include
network functionality, audio functionality and sabotage
behavior.
Check 1: Double check network settings

Check 6: Sabotage
Sabotage all network components in the system one by
one: remove cables or power down switches, conrm
system recovery, re-connect or power-up, conrm that
the system switches back to a redundant state. Notethe
recovery timing at each stage to include in the project
documentation.
Troubleshooting
If an emergency occurs in a system the most important
thing to do is to wait until the recovery is completed.
Interfering with the system before recovery takes place
