Wireless: When does the Auto null on the DX210 need to be done?
Question: Does the Auto null on the DX210 need to be done each time the system is used after powering down, only when disconnected/reconnected to the wired system or only the first time it is used with the wired system?
Answer: Typically the auto null needs to be re-done if there is a major change to the 2wire setup, like adding/ removing wired PL units, changing the way the DX210 is connected to the system or connecting the DX210 to a different PL system. Generally if the auto-null is done once and the system is powered on/off then it does not need to be re-done
The auto null should also be done if you are hearing echo betweenthe wired side and the DX210 base user or wireless users..
