However, with board operators not experienced with "normal" levels for mics and console input settings, plenty of times I have experienced when loosing pin 2 or 3 resulted in not using a 20 dB input pad, when the intermittent connection connection comes in on a drum hit, or a loud bass note, yikes, I hate it when that happens… Art [/QUOTE]
