There's nothing that can be done about that.
[note - wanted to send you a DM but you have them disabled]
Half-apologies in advance for going full-Karen about this defect, but it represents one of those things I just don't understand about late stage capitalism.
There is an existing technology (here, the rocker/spring loaded physical push switch) that just works, has no apparent functional or aesthetic drawbacks, has one really nice advantage (haptic feedback), and is presumably cheap.
So obviously the late-stage-capitalism answer is to engineer a complicated new design with unclear functional or even aesthetic benefits, and a glaring practical flaw - it breaks the commonly used control mechanism if it loses power! The new design is also inherently wasteful, because it
draws power the alternative doesn't. I assume the vampire draw is negligible, but it is there.
Maybe if the ring around the switch were an OLED wattmeter or something like that that danced to the music, one could say there is an aesthetic benefit. However, it's just an illuminated ring to tell you the operating state. Physical switches can have rings around them too.
Consider that many of these amps will not even be in the listening room. An expensive, super-high-performance multichannel amp is likely to be mounted in a remote rack, or placed in equipment cabinet. If I were a CEDIA guy, the first service call I received because a family's speakers didn't work after brief power interruption would make the very last time I sold any customer that amp - even if it is in every other way a product with superior performance and reliability - until the company repaired the obvious design defect that caused my customer to call me!
The switch requires power to work and if it loses power it has no other choice but to reset. It's just the nature of a solid state switch..
If a switch is going to destroy the functionality of the 12V trigger if the power goes out for a split second, there should be battery backup to power said switch for a time included in the circuit.
The good thing about this exchange is you've reminded me to contact you guys about the fix for my AT4007. It's good on ATI that they've realized they made a design mistake and (per
@RichB) put in the time and effort to correct it.
