Looking for some kind of external 12v trigger device for miniDSP Flex

[mglobe]

I did consider the smaller version of that earlier in this thread, but was tabled when it was mentioned that even on the lowest switching threshold setting, there might be some inconsistencies in the performance (posts #3 and #4, for reference).

If you are able to confirm that you've not encountered any issues, then I would put it back on the table for consideration. I think a potential workaround would be to use the TV as the control device (setting the threshold to high for TVs, as per the manual), and I can program the on/off sequence timing in my Sofabaton to have the Flex turn on first before the TV, and power off after the TV (which should eliminate the more audible pop that happens when the Flex is shut off before the amp).

I’ve been using this for a couple of years now without any issue at all. Works every time. The delay between powering on the flex and then having power to my amps keeps me from having any pop at all on power up. I suppose there could be variations in power consumption of the flex from unit to unit that might pose an issue, but that’s guess a wild guess.

MiniDsp Flex(x) devices power consumption specs are not currently reflecting real ones. See this discussion.

I was in the same situation ( but with a Flex HT). Master / slave power strips with wattage consumption detection is not reliable in this case with Flex HT devices.

I ended up with a box with a 12v relay (30A) made by a local french small company (but can be built for only few bucks manually) and on which a regular power strip is plugged.

An identical device was mentioned in post #12. Please explain how you would connect this to your Flex since it does not have that kind of power cable connector. Plus, the HT has a trigger out, so why would you need to have an external device like this (or a master/slave power strip)?

Use a cable adapter (or an adapter cable). It's just mains power, after all.

Arf, I did not remember (despite I also owned one previously) that the flex did not have a trigger out.
Thus, forget what I said.

In your case, I only see a master/slave power strip. These one has a configurable detection down to 8W on specs but was able to detect down to 5W with my Flex HT (but the very tiny difference between standby and idle with current Flex HT firmware made it not reliable and that's why I had to use the relay solution).

About your question why I would need it? Because I had multiple devices (power amp, subs, ...) that I wanted to have powered only when my Flex was on operating.

The audiophonics only supports 8A.

Would buy one and return if does not work. I do have another simple, inexpensive solution but would only use as a last resort. If it comes down to it, PM and will share.

How long is the delay between flex power-on and amp power-on?

I’d say a couple of seconds.

How about something like this:

then add this:

Which would make the connection the male end of the Y splitter into the Flex, then connect the Flex's power cable to one of the female ends, and run a DC to 3.5mm cable to the other female connector into the Buckeye's 12v trigger input.
