Use only one link from top to bottom as shown above.
Unit 3 shall has highest priority than 2, so as 2 than 1. Example. When there are two failures detected at unit 2 and
3, the channel at unit 3 shall be given preference than others. Thereby, arrange amplifiers that are critical in
operation at lower unit.
If it is required to force the lower priority unit into takeover mode, please switch the CH/AMP DETECTION SWITCH
at the related higher unit to OFF position.
