#pin3what?
In this video we’ve got a Klark-Teknik DN300 graphic equalizer on the bench all the way from the 1980’s. We’re looking under the hood, talking about the specs, history & how it compares to the current DN370 model from the same series nearly 40 years later. This one has lived a long life on the road it seems, and needs a full going over before being put to use. There are some crunchy feeling controls and other general maintenance that we will have to tackle in the future, which should make for a good video.
We also get into the Pin 2 hot XLR wiring standard adoption for line level equipment and how units like this from the early 80’s are wired Pin 3 hot. That’s another item on the list for the next video. Once we verify the everything functions properly and is back in working order, we can look at bringing it up to modern standards.
The DN300 Manual you see referenced in the video is available for download here – DN300 PDF. You can read more about the history of the adoption of the pin 2 hot standard, direct from folks who were actually involved over at this ProSoundWeb Forum Thread.
