Sequence for turning audio system on/off?

Some extreme cultural differences there in all aspects of rearing children there compared to "the West", not just parenting and crêche but schools too.

...I try to remember to turn mine off...I turn off preamp, then......I don't know what to call it but it's a Motu M2...

...everything else goes to sleep...

I don't have any systems that require any particular sequence. Some particular gear might require it, tho.

that's called a USB interface

I turn on the remote control, the entire audio/video system.
They are connected to each other via triggers, starting from the preamplifier and ending with the amplifiers.
However, the preamplifier is connected to a Master/Slave socket, which powers the DBX devices only when the preamplifier is turned on, because the DBXs do not have physical on/off buttons or a remote control for that.
I have never heard any pops in the speakers.

Consider a power sequencer, a device used to turn electronic equipment on and off in a specific, timed order.
For example: Furman M-8S Power Sequencer.

Interesting sequencer in the link.
I went with a vertical PDU with 18 protected outlets and a dedicated panel for the audio/video system. From my point of view, I protected the system quite well, I still have room to put other protections in the panel, I'm at the stage where I'm finally putting everything on rails and then I'll make the connections.

Consider a sequencer, a device used to turn electronic instruments' envelopes on and off and parameters including pitch up and down in a specific, timed order.
For example: Doepfer MAQ 16/3

Fun fact: jokes aside, the gate outputs are settable to 8V, so if your 12V trigger inputs are sensitive enough, it would work for turning your gear on and off in quick succession musically. Use those power cycle pops and clicks to make fat beats

My system is turned on and off with one remote control relay which connects and disconnects all audio equipment together (which are all in turned on position) to and from the common mains supply. This works fine when all units have a turn-on mute function which my amplifiers have.

Main system - source on, pre-amp on, power amp on. Power amp still thumps but it's a Krell so it would be disappointing if it didn't. No remote controls with that system but the stack is arranged in order so power up top to bottom and power down bottom to top (switch off is silent).

TV system a bit more complex - use cable box remote to switch TV and cable box out of standby. Then DAC remote to activate the DAC. Then amplifier remote to bring the amp out of standby. Switch off the same in reverse. No thumping at all on that system.

Oh yeah, if you want to switch between HDMI inputs you have to find the TV remote and use that. So that system has four remotes. Five if you count the one for the Oppo player that's also hooked up.

I'm happy that I took the plunge and bought a proper Pre-amp with 4 individual trigger outputs years ago, that turn on in sequence.... so that no fuses pop. Further, I have pretty efficient AB's, that I haven't been able to see any reason to retire yet..... and I have only experiences class D making trouble with fuses... which is also a very well-known thing in most industry products using switching power supplies. You can get around some problems with more modern RCD's made for small dc-errors - type B, since the older and cheaper class A, often get saturated in the coil by small dc leaks/errors, hereby not turning off - dangerous... or getting triggered all the time... making for huge annoyance for the user.
Though... if you have any trouble with this... always ask a professional.... it could be too late, if you get a shock, thinking that your installation protects you... but actually does not.

I got one of these, not because I need a timer but because it looks friggin cool and takes the stress off all the switches in my mostly vintage gear. Single button powers everything on and off. The little box with the outlets connects to the control unit with an umbilical so it’s out of sight. It’s just got a 12VDC wall wart plugged into it to 12V trigger the Panamax box with all the gear plugged into it. Only my amp has a very low thump when the protection circuit kicks on and there is no powering sequence that can avoid it.

While I understand the reasoning for "amp on last, amp off first" I don't bother. My amp is an AVR - it has relays that prevent any power on/off shenanigans.

Everything is turned on/off from the same remote wifi switch plug.

TV remote controls everything.
1. TV on sends CEC on signal to AVR
2. AVR sends 12V control to power strip
3. Power strip turns on DSP and one power amp
4. When DSP has booted it closes it's opto output which turns on the subwoofer amp through it's control port.
