using fusion brain to delay turn on of amp

**theheel** · 07-22-2007, 04:37 PM

im still a little sketchy on exactly what can be done with the fusion brain hardware but what i wanted to know is if it was possible attatch the remote turn on/off for an amp to the fusion brain hardware so it would turn on the amp after the computer had booted..therefore eliminated the "thump" problem?

That wouldn't be a problem at all, you'd need the brain and one relay.

Yes it would work 100% with no thump. Because the Brain wont turn on an output unless it is in communication with the program, so therfore it will only come on once windows is loaded meaning sound drivers are loaded as well.

sweet.. this is reason enough for me to get one

could i just hook up the the remote turn on wire directly to the fusion brain and go to the amp.. or do i have to use a relay method to do it.

Its not that much of a big issue but it would make it a bit easier of an install..

thanks.

The Fusion Brain switches ground, so you will need a relay or a transistor and resistor to convert teh switched ground to a switched 12v.

Not trying to discourage fb, but why spend the time and extra money when there is a plug and play device on the market that does this for you? If thats all your interested in take a look here.

That still only works off of guessing. It uses a fixed time. Some 2.5s some from 0-30. Computers dont boot the same every time. If you have bhigh end components that are sensitive to pops, or are in competitions where pops are an absolute no-no, then the Fusion Brain is perfect.

The FB wont just guess. It will wait until windows has loaded, meaning 100% that audio drivers are loaded. No guessing needed and perfect 100% of the time.

yes, i suppose. I have been using that 0-30 second one for the last year and have not heard a pop since. If I was to restart my computer for some reason while driving, the pop will be heard.

well and the fact that you can do a whole lot more than delay turn on of amp for only $25 more

I'm sure this will be asked again in the future by others, but could you please provide a schematic for turning on an amp by using a transistor and resistor? Would one need a PNP transistor and what size resistor? Thx.
