Standbye appears to be a soft turn on. When I flip the breaker at the back of the amp I do get the surge current. If I use the front panel button or remote the amp does not have this same surge. In standbye the amp is partially powered up and drawing current. I have had a FPB 200 and now I run a 400CX. Both amps turn on the same.
Standby Mode in Krell FPB power amps
When most large power amps are turned on, they draw a large surge current from the AC line for a second or two while the large power supply filter capacitors are charging, and then settle down to an idle current level. My question is:
When Krell FPB power amps (the 250M monoblocks specifically) are switched from ON to STANDBY, do the power supply capacitors remain charged, so that there is no large turn-on current the next time you switch back to ON (i.e., only a change from STANDBY current draw to idle current draw), or are the power supply capacitors discharged, so that there is a large current surge every time you switch back to ON?
I E-mailed Krell this question, but I haven't received a response from them as yet.
Thanks!
