OK, so I have had my BV7-40mkIII updated to the latest software, due to some faults, now got the Black menu
In the menu for SOUND, there is an option for AST on/off this is currently grey'd out and con not be changed. in the SERVICE menu for Sound Config, if you choose SOUND SYSTEM there is the line Adaptive Sound Technology - DISABLED.
Anyone know what this does and how to enable it
