Wow – it’s a proper technical article on the TechBlog! I have Daniel Grubac of DV2 en France to thank for bringing this to my attention and I am not too proud to admit that I didn’t know this worked!
In days long gone, when designing presets for the DP224 and DP226 in Library Manager, when it came to building a set of presets into a binary file, the option was available to additionally disable changes to the crossover configuration by ticking a box (no need to go into this further now – email me if you need ot know more… ;))
This facility was (somewhat strangely) left out of the 4 Series as an option, and Daniel enquired today about what to do instead. As it transpired, after a little head scratching, he was one step ahead of me by thinking about locking things out using the standard system locking through AudioCore. On thesecurity set-up window, there is an innocent little check box that is labelled “Configurations” as you can see below:
Considering I wrote the AudioCore manual, I really ought to have known that this did a little more than just prevent you from accessing the ability to design a new crossover. If you tick this and nothing else (so all other aspects of the unit remain unlocked) and send this locking status to the unit, what happens is that all menus accessible via the menu key disappear, with the exception of the memory menu and the security menu.
The implications for this are that if you’ve set your unit to a certain Interface mode for remote control purposes, or have enabled AES outputs for example, and you want to protect these features from unwanted change, but leave the audio editing fully accessible, this is how you achieve it!
