Agree 100%. I was hearing a VERY strong thump, each time I powered down my 6kdsp. For clarification, this was happening when my smart strip was cutting power to the amp, after I sent the "system off" command from my universal remote. The thump was loud enough that it would make people in the room jump, if they weren't ready for it.
I asked a buddy of mine, with a strong background in electrical engineering to come up with a harness that is as close to plug and play as possible, and he did. The harness allows for either smart strip or 12 volt trigger control and completely kills the power thump.
I did the install in about 15 minutes and I can now power down my amp via smart strip or via 12 volt trigger, and it's dead quiet ( I tested both methods ). I also recently helped my neighbor install the harness/relay in his 2 amps, and the thump is also now gone.
It's nice being able to power down the system now, without having to turn off the amps manually or give everyone a verbal warning about the power cycle thump.
If anyone has questions, please send me PM, since I may not be on the forum as much as I usually am, due to a few work projects I have going on.
