Powering on/off amps with preamp trigger


Hi, I want to use my preamp trigger to power on and off my amps. I have read that people prefer to power on the amps after the preamp and power off the amps before the preamp. If I use the preamp trigger, then power off and power on would be simultaneous with the preamp. Is there a danger in this? If so, what are they and why do people prefer to stagger the power cycling of the amps and preamp?

Oh yeah, before any one says it, I am an indeed too lazy to take the extra step of turning on and off my monoblocks. Yes, this is purely a matter of convenience for me.

Thanks everyone. I will heed the advice and do what everyone says. Here is how I will accomplsh this using my pre which has 2 output triggers (by the way, my pre allows me to assign the triggers to my remote so I can manually turn on or off the trigger):

One solution is to use a normally open 12v relay. I can use trigger #2 to actuate the relay. I can then wire trigger #1 to this relay. So when the cp is powered up, trigger #1 will output 12v (assuming normal logic). I can then assign one of the remote function keys to toggle the relay. After the cp is turned on, I can then use trigger #2 to open the relay allowing trigger #1 to power up my amps. Before powering down the cp, I will toggle trigger #2 so that the relay is open, essentially cutting power from trigger #1 that my amps see.

What does everyone think?
Tboooe,
There may not be enough current available in the trigger circuit to close a relay that switches 120v. You should look at the specifications on available relays and check with the preamp manufacturer. I tried this once and it didn't work.

Why did you buy monoblocks then?

Reading that makes me glad I sold all of my seperates and went back to an integrated amp.

Have fun, :-)
