Trigger circuit for a denon AVR

[Loupy]

Hi Everyone, I have drawn up a rough circuit for a trigger box, to power several 12 volt devices,
Can some one please have a quick look at the pic, just to make sure i havent done anything wrong.
Thx
Peter

Ever hear of SIB-KIS? See It Big- Keep It Simple.

You can do this with a simple relay and wall wart 12VDC power supply, triggered by the Denon. I have done it many times and it works great- I used a plastic project box or if time was short, an electrical junction box with no holes. a Bosch-style automotive relay draws about 150mA (typically less) and it's easy to wire-

Tab 85- +12V from wall wart
Tab 86- - from the wall wart
30- output from relay, to the equipment
Tab 87a- NC (No Connection)
Tab 87- +12V, looped from Tab 85

The wall wart obviously needs to be sized correctly.

What model of Denon AVR? If it's older, it may have courtesy outlets on the back and they can be used to power a wall wart- I have done that many times and it always worked.

If you're working on a trigger circuit for a Denon AVR and need a reliable FPGA for signal processing or automation, you might want to check out the XC6SLX16-3CSG225I. This Spartan-6 FPGA offers low power consumption and high performance, making it a great choice for AV and automation projects. I found it on Ovaga, where they have detailed specs and availability. Has anyone here used an FPGA for AVR automation? Would love to hear your experiences!

Thanks for the advice, you saved my day.
