12V Trigger from AVR3805 to B&W DS7

[LKinDC]

I am going to be setting up a system with a Denon AVR 3805 and B&W 700 series speakers, including monopole / dipole optional DS7 surrounds. I would like to use the Denon 12V trigger to switch the speakers from monpole to dipole operation, but I'm not sure if I can and I'm not sure how to make the cable.

The Denon specifies "DC 12V 25mA MAX.".
The DS7 specifies "12V trigger current requirement 45mA".

My questions are:

1. Will the 3805 put out enough current to "flip" the switch in both speakers?
2. How do I configure the wire (i.e. mono plug, plus to left speaker, left speaker minus to right speaker plus, right speaker minus to plug minus)?

From everything I have read, I will need to buy a 1/8" mini plug and make the wire, and I'd like to drive both speaker siwtches with one trigger if possible. I don't know a lot about electricity but have no problem making the wire if I know I've built it correctly.

Cable Help Only

The only thing I can help with is the cable. You can get the cable you need from Radio Shack for $3.99.

Nobody has an answer for this?

With all the experts on this site I'm shocked that there isn't someone out there that knows a little bit about electricity. Nothing? No one?

Other Options

If no one has an answer to this, is there somewhere you might recommend getting one? I was told by a friend that if the amperage doesn't match that I might need to get a relay, which from what I understand is a electronic switch that allows you to output more power than the switch signal (I would in essence be triggering a trigger). All relays I've found on the web are electronic components that would have to be built into some piece of electronics; not standalone products. No word back yet from Denon, though I'm not hoping for much there either.

The Denon specifies "DC 12V 25mA MAX.".
The DS7 specifies "12V trigger current requirement 45mA".

Seems pretty clear you can't use the Denon to trigger your DS7s. I'd ask B&W what their recommendation is.
