Has anyone heard of splitting the 12 volt trigger out of a 970? The 970 has only 1 - 12 volt trigger. I plan to use two amps one for the front channels and the other for the surround speakers. I of course want to have the amps come on with the 970. Does anyone know if I can split the 12 volt signal? Any comments would greatly be appreciated.

On some amps the 12v trigger signal can be daisy-chained from one amp to another. I think the Outlaw 220 monoblocks do this and some of the other Outlaw amps might too. I'd be wary of splitting the trigger signal - if you connect the two amps in series each will get only 6 volts - insufficient - and in parallel each gets only half of however many milliamps the 970 puts out, which might also be insufficient. Others here probably know more than I.

If I am not mistaken we both have the same surge protector - Belkin PF 60. So I could use that 12 volt trigger but I am not sure on just how to "trigger" the 12 volts. Presently I have the 970 plugged into the surger protector. I thought of using the non existent 120 volt output but as mentioned, it is non existent on the 970. Thank you for such a quick reply. I have a few days before the new amp arrives. To think that I bought a new amp to alleviate the headroom concerns only to come up with a new concern. What a great hobby! Hopefully these concerns will not end.

Tried using the PF 60 to turn on the 7075. I guess my house wiring is a little different from yours. It kind of turned on "hard" instead of "soft" when using the 12 volt trigger. No damage though. Thank you for the suggestion. I emailed ATI and "Mike" replied indicating that all ATI amps only need 5 Ma to turn on. I then phoned Outlaw (today) and they said the 970 puts out 50 Ma, more than enough to "trigger" two external sources like amps.
