setting up a rack

[pure-krypton]

This may seem like a bit of a stupid question to ask but I have an Engl 530 Preamp and a Marshall EL34 50/50 Power Amp.

What's the deal with setting the line out level on the back of the preamp? Do I set it high and the power amp gain low or vice-versa?

I have an Engl 530 as well... the line level knob in the rear's the "master" output level for the whole preamp before its outputted to the poweramp; it also controls the volume level for the headphone out.
The premise is to have the power-amp at a suitable volume but not cranked while preamp at mid-level - you don't want the preamp signal clipping before it reaches the power amp stage I have mine a little half-way before going in a Mesa 2:90

I'd say... from 0-10, set it about 8 and let the power-amp do the rest.
