Krell Ksa 150 remote trigger

agp · 25th June 2004, 06:27 AM

I have several KSA amps that I would like to remotely trigger. On one of the KSA 150's there is a small red dual rockerswitch in the middle of the front pcb that allows you to change the function of the on/off switch. After changing the switch settings, when you plug in the amp it automatically turns on. Unfortunately, none of the other amps has this newer front pcb. Short of buying new boards from Krell ($$$$$) does anyone have any ideas for a mod of the power switch so i could use a 12v trigger or a low voltage relay trigger on the outlet it is plugged into ?

That is quite interesting, because when i brought my unit from america to germany i had to change one of the red switched from 1-2 so that they both show 2-2 in order to make the unit accept 220V. Do you mean the same 2 red switched right on the front PCB?

Hi,
the ESP site has a signal sensing switch (relay) to switch on and a delayed off to control power amps.
