If I understand

His AVR is limited to 40ma from its 12v trigger out. He is trying to drive 4 devices and it won't do it properly. It would do 2 subs, but not the amps too. One of those crummy nuisance situations. He wishes the Axiom subs/Ada amps had 12v repeaters to solve the issue but they don't. He is unhappy about it but has a few ideas for workarounds he can use.

Matt, be sure to share your solution so others may benefit. smile

The ADA amps use a much larger relay inside them than the EP sub woofers. As a result, they require larger amounts of current from the pre-amp trigger to switch them on.

Anthem for some reason decided to give a measly 40mA for the trigger line out. Not enough to power many external component switching, especially considering it is a PreAmp and needs 11 channels to drive the speakers. (13 for me as I have LFR's) + sub woofers.

I am going to need some help from someone who knows electronics as I know enough to get myself into trouble, but not enough to understand how to get around it.

My first thought is stereo vs mono cable as well, although I have to admit that 40mA seems pretty low for a trigger output.

I did find at least one 1/8" mono cable locally though:

https://www.amazon.ca/TNP-3-5mm-Mono-Cable-6FT/dp/B01MEBXOOP/ref=sr_1_13?ie=UTF8&qid=1509908901&sr=8-13&keywords=1%2F8+mono+cable

I need to stick my head into Sayal next week (they often have buckets of things you can't find anywhere else) so will keep my eyes open. Will also look at your relay thread tonight... rain has stopped briefly so need to run out and get back to brush cutting.

BTW apparently trigger incompatibility seems to be a problem since AFAICS there are no industry standards, but the usual workarounds seem to be:

1. If your master unit has a switched outlet plug a 12v wall wart into it and use that to trigger the other equipment

2. If no switched outlet then get a current sensing master/slave power bar (something I did not know existed until just now) and plug the wall wart into a slave outlet.

Dumb question - do the amplifiers on EP500 and ADA1000 generate much heat when idle ? If not I would be inclined to leave them on all the time rather than switching on and off, although the whole "switching on and off is the hardest thing on your equipment" may be an old wives tale, not sure.

I probably should switch my old Adcom off when not using it, since it definitely generates some heat even at idle.

Too late to edit, but might actually end up a couple of bucks cheaper ordering from the US:

it is a bit of a pitty that this message board doesn't allow you to embed photos (upload) but only link to them. I finally got around to making my 12v switch box on Friday before it started to rain. I even took the time to take step by step photos that I could post. But as there is nowhere to do that here I guess I am out of luck.

But needless to say, I finally got my ADA1000s to work right with my Anthem preamp. I learnt a bit about soldering. I figured out that I was right to order some extra parts as you can't always count on the printed guide to be correct when you order parts of ebay from china. I think it looks pretty good and works rather well. As an added bonus, now my LFR DSP also gets to be turned on and off by the additional 120v plug that I also added to my 12v trigger box.

Yes its a bit of a hassle to upload to another site then link to this site , Axioms forum is a bit dated to say the least. Anywho what was the purpose of your switch box. BTW i use IMGUR which is still free and it works ok.

PrimeCables has 3.5mm mono cables for cheap, if anyone is still looking: https://www.primecables.ca/p-370665-cab-...black#sku383505

Yeah dude, can't wait to get going. Speakers and amp have been ordered. Just need my contractor to start on the basement.
