Amps and subwoofer on power strip

[olds1959special]

I have my amps and subwoofer on a power strip to power on and off. Is this okay? I noticed something, my Kenwood L-05M make a clicking sound when I turn them off with the power switch and my other Kenwood L-05M’s labeled Trios do not. They are in different systems. I thought these amps were the same or is there another reason why some of the amps seem are making a clicking sound upon losing power while the others are not?

It's common for control units to output a DC pulse when turned off. And control units often turn off quicker than amps and subs.

The pros have turn on and turn off sequence rules.

Turn ON sequence :
1) audio source units
2) audio control units
3) amps (and active speakers)

Turn OFF sequence :
1) amps (and active speakers)
2) audio control units
3) audio source units

What’s a control unit? I’m just using a power strip (relocatable power tap) that has a switch.

A pre-amp, mixer or receiver if you are using it's line level outputs to active speakers or subs.
I guess an audio interface could be both a source ans a control unit.

If you examine the schematics, you'll see that it is either the remote turn-on relay or the DC protect circuit relay—possibly both—that is/are triggering/turning off on power supply collapse when the power is interrupted by turning off the AC power strip.

Is this okay to do on a regular basis or should I be just using the switches on the back of each amp?

From what is indicated in the schematics, it probably doesn't make any difference whether you turn off the amp with the switch, the remote trigger, or by pulling the plug/switching off the power strip.

How long should you wait after you turn off the amps before you turn off the pre-amp and DAC? Don't the capacitors have to drain a bit?

That likely happens on the order of a second or two and really isn't something to worry about.

At least I myself with my PC-DSP-based multichannel multi-SP-driver multi-amplifier fully active setup, I have been being careful in "startup/ignition sequences" and "shutdown sequencies". Please refer to the bottom portion of my setup sharing post...
