Axiom Home Page Forums General Discussion Technical Questions EP350v2 versus EP350v3 specs

I believe the test tones are preset in each receiver for either 75 db or 80 db when it says 0, it is just a reference point.

So the reference point can be what ever you want. Start at the usual LF adjust receiver volume to have LF speaker at 75 db and 0 on the speaker level and then continue from there, just as HAY said.
