I upgraded the Amp 2.1 to the firmware 4.6.328252 and fail to make the different Eq presets switch working properly:
I set an EQ setting in ACP workbench, and save the configuration to Flash with “group index”: 0 (Group name: KTV).
then, I configure another EQ setting, and save it to the group index 1, and so on, up to 4 different EQ settings.
When using the ADC num keys 1 to 4 to change the settings, I hear a beep when pressing the buttons, but no change in the EQ
Note that the other ADC keys work properly.
PS: when pressing the ADC “Num4”, there is no beep.
I dont see what is wrong. Some help would be great
