Re: BEs and System DSP
I was down this road before black box presets. Every BE seemed to have a different idea of how a rig should sound and felt that the way to achieve it was to make DSP changes in our OmniDrives. Eventually I locked them and told the BEs that only our boss had the password, and he was in Argentina.
Now with the VerTec rigs, all the DSP is in the amplifiers. When a BE asks for DSP access I tell them "it's the stock JBL v4.2 processing, it's locked by JBL. There is no access." EQ the rig any way you like, and you can change subsystem alignment (FF, L/R, subs) at the desk if you choose to do so."
YMMV and all that, but if a rig was properly aligned and tuned based on factory processing there is very little a BE can or should be doing inside the DSP.
