Yeah, being able to trust your meters for correct level information is pretty important indeed. Now there is the whole issue on what causes the level meters to react. Some parts in the music are louder than others, hence the “bouncing” nature of the meters with the music and - for example - when vocals kick in.
I could see how turning UP the bass would increase the volume, this is actually expected behavior, but the other way around, not so much.
I just tried to replicate this behavior and I can. I have my EQ settings on default (i.e. not kill and standard frequency changes).
A few notable things seem to happen (all EQ on 12 o’clock, gain just under 1st white led peaking = 0dB):
- in general I lose one LED when turning the bass fully down (expected, taking out a major part of the musical energy/signal)
- it SEEMS like the LED below the highest blinks more than the one above it (where you’d expect the top one to be more of the blinking one (this COULD have to do with a feature retaining the highest level just a tad longer to give better visual feedback on peak levels
- then when the vocals kick in, suddenly the first white LED comes on (blinking with the song). When I then return the bass to 12 0’clock, the white LED no longer lights! So, when increasing the bass the white LED does not come on, while it does with the bass turned down.
It has never bothered me, as I run all my tracks through Platinum Notes anyway, besides I just gain for average 0dB levels when loading a track and after that just keep the occassional eye on the meters to prevent anything odd to be happening.
But I can see how, when you are recording, this could be a bigger issue.
Not sure if this helps any, but there you go.
My three cents as usual.
