    USB to 12V trigger input?

    Yes and no. I came up with a solution that works reasonably well and is still in service: https://www.audiosciencereview.com/forum/index.php?threads/looking-to-build-a-simple-solution-to-control-12v-amp-trigger.24288/page-2#post-1019792 I was not able to get power out of the USB on the mini...

    Looking for a 12v trigger transmitter & receiver

    Instead of using the trigger, the tv or avr would act as control and the power strip would power up the pre-amp.

    Looking for a 12v trigger transmitter & receiver

    There are smart power strips, if that’s safe for your pre-amp. Amazon link

    Looking for a 12v trigger transmitter & receiver

    The new topping E70 dac has a trigger output and they say the dac wakes up from any input. It would be isolated from the avr if connected by optical cable.

    Looking for a 12v trigger transmitter & receiver

    If you only need the trigger to provide power during your own sessions, perhaps you could introduce a new, isolated source of power. See reference to a gizmo with its own remote: ASR post Amazon link

    Looking for a 12v trigger transmitter & receiver

    There are a number of gizmos available that may help. Please confirm that you wish to control the pre-amp when then AVR is powered on? Does the AVR have a trigger output? Does the pre-amp have a trigger input? Do you use a programmable remote to which you could add a device to control...

    A Call For Humor!

    I am sticking with (b) 3. "How many times will circle A revolve in total?" Circle A revolves 3 times in its journey around circle B. To claim that the entire journey constitutes an additional revolution, as defined by circle A moving in a curved path around the center of circle B, conflates...

    Faster electric razor

    Years back, I had a plug-in electric razor. I used a small device between the razor plug and the wall outlet. It made the razor run faster. I believe it was called a Shaver Jet, but I find no mention of it online. I recall someone said it converted AC to DC, making the motor happier? Do...

    Topping DX7 Pro+ Review (DAC & HP Amp)

    Since this has a trigger, I am considering this for my living room TV. The trigger extends the dac as a front end beyond simply adding a volume control, input switch and infrared remote. The trigger - as a simple, reliable power control for an amp - is big for WAF/ease of use. There are few...

    Looking to build a simple solution to control 12v amp trigger

    I simply placed the device adjacent to the amplifier and ran the IR receiver until it is about flush with the face of the amp and the streamer that sits next to it. It still works just fine :)
