12V DC Trigger for 13 Amp IEC

[dalryc]

I'm looking to automatically power on mains powered Quad ESLs from my 3.5mm DC trigger output on my pre-amp.

The only option I can find is:

Unfortunately, there's a €160 minimum spend.

Are there any off the shelf alternatives?

I looked and couldn’t find anything. I ended up using a current switched socket.

Just leave them on all the time, I did with mine.

Unfortunately, my cats think my new speakers are their new scratch posts so I can't take any chances of leaving them powered on.

Just thinking there must be some way with a hive or homekit enable mains socket triggered from bluetooth out of the 3.5mm

 

[Pete MB&D]

Their many ways of swtiching the power but if you aren't a good diyer used to working with mains they all can be very dangerous.
You can use a relay or a solid state relay but it will need a box earthing etc..

I've got a radio controlled set of plug in switches so one push on the remote turns all five plugs on.

Doesn't seem to degrade sq.

 

[dalryc]

I did have a set of them too - they worked well with my Class A amps that had difficult power requirements which didn't work with smart Alexa plugs.

It may be an option, but it does increase the remote control count.

I use HomeKit to turn on my amps’ sockets when I turn on the TV. Very handy I must admit!

this below could be a good solution, but as Pete says, great care is needed working with mains,
it would need to be put in a plastic mains rated enclosure, correctly fused etc.

the device you linked looks good value, maybe a group buy to get past the min order issues?

 

[dalryc]

I'd be up for organising a group purchase - I think we'd need to buy six of them. If you're after some, PM me. I'd need either two or three.

Are there any extension blocks that will power on slave sockets when a device connected to a master socket is powered on?

I used to have such an extension for a PC base unit to power on peripherals, but cannot find any now.

Something like this, I guess? Doesn't get very good reviews, though…

[dalryc]

That looks like what I'm after though the reviews are off putting.

 

[DoctorRad]

There's also this, if you can wire it up safely… you could, perhaps wire it into the PSU for your preamp, for instance…

Kemo make some really useful kits and modules for the 'tronic makers and tinkerers out there!

It's a probably overkill (or a massive pro-audio sledgehammer to crack this particular nut) but you could use an EMO systems slave switcher:

They're intended for slaving from a master unit with a keypad, but I believe it'll trigger from the 12v? They pop up on eBay usually having come out of PA installations - not my auction but there are some on at the moment (Canford do a separate cover for the mains terminals):

I'm looking for a more plug 'n play solution.
