Setting up a D400

[SteveO...]

Hi
I've taken this opportunity to upgrade to my 200 to a 400.
It arrives tomorrow and just wanted to prepare the config
Do you need to load the same config file on both sd cards or just on the master sd card?
Thanks in advance

Get over to your existing config on the Devialet site.  You can "add a Devialet" to your existing config; make sure you have them set as mono, one for each channel.  Also note the speaker terminals to use, the mono config uses only the amps' red terminals.  Once you've set up your new config you can download the files.  There are download links next to each unit, so you'll have one each for the Master and Slave/Companion.

So, in short, they take separate config files.  Enjoy your new toy
