Adcom Preamp...what is 'contour' button for?


This amp (555 GFP) has a 'contour' button that seems to only boost bass output. Is that its only purpose?

its basically a loudness button without havivg to tell anyone you have a loudness button on your high end amp
Can anyone help??I have the same pre amp (Adcom GFP 555II) and was wondering- because I am not home to look at it- does it have sub out jacks?? thanks, Dave
Koa:

I have the "I" version ... which did not have a sub out (they really weren't used much in 1989). Check Adcom's website as they have downloadable user manuals.
