Hi everyone,
I’m seeking advice on using a smart plug to power my Class D amp on and off. Here’s my current setup:
Amp: AUDIOPHONICS AP300-M450ET (Hypex SMPS600 + Purifi 1ET6525SA).
Smart Plug: Nous A8T (rated for 10A, 230V).
Is it safe to use the smart plug for power cycling the amp? I’ve been running this setup for a week now, controlling three amps simultaneously (each with its own switch, controlled via Home Assistant), and haven’t encountered any issues. I’ve tested turning the amps on and off, even while playing audio, and there’s been no thump sound or other problems.
The amps also feature a 12V trigger input, but I’m unsure how it functions. From inspecting the internals, I don’t see the SMPS600’s standby pins connected, so I’m unclear how the 12V trigger is implemented. I’ve included a photo of the amp’s internals for reference.
Are there any potential risks or downsides to continuing with the smart plug method? So far, it’s been very convenient, requiring no additional cabling. Any insights, suggestions, or advice would be greatly appreciated!
Thanks in advance!

As long as the smart plug can pass enough current for the amplifier, it should be fine.
I've been doing this for years, my setup is in basement need to turn on tube preamp to warm up for at least half hour, being lazy so use one smart plug control dac+preamp and another to control class d amp, no issue so far.
A better question, repeatedly pass current to the amp without failing.
I use appliance remotes for my amplifiers.

Thanks for all the helpful replies! I feel much more confident now and will go ahead with using the smart plugs without any worries.
Cheers!
