Re: Digital desk that can bus a mic input to more than 1 preamp?
Just because it is possible, doesn't mean it is practical or cost effective. It is not clear to me what possible benefit accrues from doing that, that way.
If you want to send one input to two channels, it is far easier and cheaper to do that in the digital domain. Relative gain between the two stems can be accomplished with a simple multiply in the digital domain. The mic preamp with A/D convertor is a major cost element inside a digital console. For one-off special applications use a splitter cord. For larger parallel operations that needs to burn 2x the number of inputs , just use two consoles.
Note; In my future vision, console inputs will automatically manage clipping and nominal gain setting, Console input trims would be relative gain, and automatically compensate for clipping events and the like. There would be little reason for anybody to mess with first stage mic pre gain.
