Adding a power trigger to an amp that doesn't have one

Hello Everyone, 

I might be buying an amplifier that has a remote but doesn't have a 12v trigger port. I need it to have one so that I can turn it on with a 12v from my AVR. 

Is there a device that on one end has a 12v(mono standard 12v plug) and on the other end an IR transmitter that can be programmed to the power button of the remote from the amp? 

I don't want to use a universal remote since none of them have the mouse/pointer ability to move like the LG magic remote (at least from what I could find). 

Thanks!

For the unit I mentioned, you would leave the amplifier turned on and plugged into the DigiKey piece. As show in the description, there is a trigger located on the side of it that is activated by any small AC or DC voltage up to about 30V. You would connect your trigger out wire from your receiver to that port and when your receiver turns on, it would trigger power to turn on your amplifier. Your trigger out is probably 12vdc.
