Volumes keep getting out of sync on chained amps

[andrewmalpass]

I’ve got my amp ultra permanently chained to an amp as surround speakers.

Trying to work out why when I come back to it, the volume of the master and slave amp is not the same.

I’ve set the volume steps to be the same for both amps.

What should I be doing?

when I come back to it, the volume of the master and slave amp is not the same.

Can you expand on that?
Come back to it hours later? Days later?
How far off are they?

It reads like you only change the volume on the amp ultra, and expect both to have the same volume number displayed in the app.
