I leave my preamp on 24/7 - same as my amp. Both transistor. No thump from either on turn on/off.

Carvin Audio Explanation. Substitute Preamp for Mixer. "THE RIGHT ORDER TO TURN THINGS ONBefore anything else, let’s review the power up sequence for a common live sound scenario. Power up in this order:
Some power controllers have sequenced power banks that do this for you. |
I've always read proper turn on sequence is: 1. Preamp along with everything connected to it. 2. Amp. Shutdown is the opposite BUT..... My preamp is connected to my amp with a wire that turns both on at the same time when you do a startup with the preamp remote control. Neither the preamp nor the amp instantly come on, there's a few seconds of delay. You can here a click in each when they actually power on. I assume this makes the startup procedure okay? Just want to be sure, thanks.

The inrush current is the same whether first or last. However, turning it on first will cause the amp to amplify any thumps caused by upstream components, if any. The amp may cause the AC voltage to dip momentarily, but that's not a problem for any other components that are already on. |
