config question for dual mono

[hardcore]

Found an anomoly with only the Master programmed:  The balance control has no effect

Re-doing the programming as a 440Pro Dual, then saving the two programs separately and loading Master and Companion (as Devialet call it) on their own SD cards, the balance operates

I should have listened to you the first time.  I have not had the occasion to need a balance control, but this was my way of checking everything

Just curious how the old configuration (no companion configuration) could have worked.

Wanted to check what speaker terminals are you connecting your speakers to on the Devialet? In dual-mono mode, the amps act as bridged mono-blocks, so you should connect the speaker cables to the red +L and +R terminals on the speaker outputs.

And each amp needs to be configured to output either the Left or Right channel.
