Preamp

bradley_horwitz hi,

what is your source? and does it have a volume/level control?

If so have you tried to use direct into the Krell? 

Cheers George

You’ve got something wrong there Brad with the 6-12v DC. 

The output from source or preamp is AC, if it were DC you’d blow amp and speaker up in an instant.

Your FPB-600 as tested by Stereophile puts out it’s full output of 935Wpc!!! into 8 ohms, with 3.9v of ac going in.

So as you can see, if you were to halve that to 2v you’d still put out 415w into 8ohms which I’m sure is still plenty enough for whatever speakers you have, most dacs and cd player put out over 2v some even 6v.

So if you have a source that has volume control try it direct into the Krell, I’m sure you will still have plenty left for ear splitting days or parties.

BTW: That 6 to 12 volts (DC)? you were told is for sure the voltage for remote switch on (power up) for the Krell, from an external source. But I'm sure you can switch on the Krell manually as well. 

Cheers George 
Here is the manual if you don’t have it
