Moving from 220pro to 440pro (dual mono)

[zambie]

Yes, on the digital port
On the configurator, select 440PRO
I also changed the optical in to trigger out on the master and attach a cable to the same port onthe slave

The improvement is really worthwhile

Thanks - can you explain what triggering out the master means?

When the amp is switched on, the trigger becomes 12V+.  This will activate secondary equipment.   The dealer who sold me the extra 220PRO included a cable and instructed me to set it up this way

The remote is assigned to the master only.  About 5 seconds after switching on the master, the slave switches itself on

I use AES in for digital and co-ax digital to the slave

Thanks - very interesting insight. So - basically optical cable between master and slave for the trigger ... Appreciate you sharing.
