what is roll feature

such as, if you want to burp at volume 20, and you mute it before the burp. when you unmute it, it does a roll from 0-20 with all the levels inbetween. so instead of going directly from 0, to 20....it does 0,1,2,3,4,5,6,7, etc....

why would you want to roll it up? it makes the voltage lower as you reach your peak volume...

I've read it is easier on your equipment, and your score can be higher. Whether or not this is true, I have no tested it so I do not know. It would have to be a really quick roll up and down though.

To the OP, why don't you just roll the volume up yourself? You don't NEED the HU to do it for you.

seems like rolling up the volume would eat up your voltage before you reach your peak spl, whereas if you just crank it on pause and hit it, you get the full voltage...

the problem with that is, in some classes where you can only have one battery, if the amp doesnt like it, it may kick into protect. i could do the roll up myself, but have heard there are certain alpines and kenwoods that actually have this feature already.

if you are running your amps at too low of a load, they may go into protect. But rolling up the volume can prevent that
