PM8500 Amps muted on startup

Hello Team,

I have a recent installation where the PM8500 amps are coming up in fault mode when they are started up with a power sequencer and no audio is passed until the power sequencer module is reset within the rack. Then they power up and pass audio. I do have the alarms condition panel set to show faults under various conditions (see JPG attached) but nothing in the help file that I could find indicates that the amp will mute at start-up when these are activated.

Any ideas? I need to go out there to troubleshoot this week.


Bruce, do you have make/model on the sequencer?

I am working on getting that info for you now.
