As y’all know, Sled Dog likes to run our shows preeeeetty loud. We like to bring the boom and shake the room. As you engineers in the audience know, this brings a massive feedback battle.
For a while there, we ran into the issue where we were getting just a smidgen too much feedback for our liking. Now you should know, we don’t use a feedback eliminator. We don’t auto EQ. We use our ears. Tony Huerta turned us on to the problems those two devices can cause in a live setting. Sure, we use an RTA to be a bit more scientific about it, but auto EQs can stumble upon nodes in the room and boost in ways that _produce_ feedback. Similarly, feedback eliminators can make some strange choices and fight the engineer. Instead, we just run (digital) graphics on groups and outputs and use the two best tools we have: our ears.
Before we got our VENUE, we ran purely in the analog realm. Allen and Heath live board with outboard comps, EQs, and effects. In order to overcome the noise floor, we would gain to “maximize” the channel (while leaving room for plosives) and bring down our mains fader. Novel concept, right? Bring _down_ the mains fader. Oddly enough, this worked. _Very_ well.
With the VENUE, we were seeing too much feedback for our liking, especially when dealing with outboard pedals, as typically used by smaller professional aca groups. Our solution…was to flip our gain structure on its head. We cut our input gains by roughly 10db all around. We are now seeing no feedback…period.
This leads us to believe that a) the Avid pres have a pretty high THD and b) we probably should have realized that with a 24-bit bit depth, there’s no reason to maximize the channel and there is no “noise” in the digital architecture.
Moral of all of this: If you are working on a digital console, turn down your gain.
