Gain structure generally refers to setting proper input gain to achieve the best signal to noise ratio. Optimum gain is not just turning it up until it’s in the red as a lighting guy once told me! Hmmm.
Gain staging occurs at many places in the sound system- between the soundboard, signal processing, amplifiers, inside the soundboard itself, and from the various sources coming from the stage. The level coming into each piece of gear should be the same going out and the next device in the signal path should also be seeing the same level.
This is called ‘Unity Gain’. For example; if the output meter on your soundboard is showing 0dB (nominal) and the next device in the signal path is the system crossover, it should be seeing 0dB at the input and the signal leaving it should initially be 0dB, and so on down the line.
While some devices are used specifically to increase or decrease gain, and you may make adjustments to output levels to suit your needs, if you...
I recently got called last minute to mix a few shows for Janet Jackson. The gear was already on the truck on its way to the first gig and I would be mixing on a Digico SD7. I have mixed on Digico a handful of times over the past several years but the Midas ProX has been my console of choice and where I have spent the majority of my time. Needless to say the Digico and Midas platform are quite different.
This is a fairly involved production with 80+ inputs so it was going to require some serious thought. If you’ve read my previous blog about console workflow, you know that proper layout of the console is very important to mixing a show of this size.
So I needed a crash course in Digico.
Here’s what I did-
I downloaded the SD7 offline editor and started building my file while watching the videos and scouring the manual whenever I needed...
