New Monitors - Volume Settings???, Best level settings Options

[markwhite]

I have recently purchsed some new Tapco S8 monitors....which are excellent! I am running them through my G5 Mac with a Soundcraft analogue mixer.

What settings should I be going fo r on each to get the best signals etc. I understand the mixer settings, but my monitors have input sensitivity, do I put it on full or lower and have other stuff higher. There is sometimes a quiet hiss on the monitors if they are turned up too loud, this should'nt happen in a small bedroom setu, surely?

Thanks for any advice!
