Powering on/off amps with preamp trigger

whenever I turn off my amps I always turn volume to zero as well as mute the preamp,

When I turn on my preamp it always comes on at zero volume (ARC Ref3)

The potential for blwing a driver exists if you turn off your preamp before your amp. Good speakers will blow a resistor before the friver but the transient to the speaker can be excessive.

As been stated...
Pre on first, amps second. Amps off first, pre second. Zero volume and mute. I don't have a 12v trigger on my pre, but do on my monoblocks. I wired one amp to trigger the other amp (one less button to push), and the JC-1's have a timer delay. So, one amp powers up nice and slow, then triggers the other amp, which powers up nice and slow.

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.

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.

Why did you buy monoblocks then?

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.

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

Have fun, :-)
