Re: Presonous 24.4.2 going full gain suddenlyIf, for example, the receiving component is expecting 0-2V to be 0 and 3-5V to be 1 then an internal voltage drop causing the transmitting component to send out a high signal of under 3V will be unpredictable at best. Similarly if there is something wrong narrowing the voltage range for low signal you may get a 1 when you wanted a 0. That signal that was supposed to be 1111 1111 may end up 1000 0011 (or the other way around) with even an internal power glitch lasting a fraction of a second. For things that are a continuous stream of repeating data (such as DMX) it is usually self correcting and some protocols have error correction built in. But if what comes out is a one time command or you are using a system with a low refresh rate then the mistake can become very noticeable.Combine that with other software/design issues and it is hard to believe there aren't more problems with digital consoles not plugged into good UPS's. Good power supply design will get you pretty far but there is only so much you can compensate for on a lower priced piece of equipment before it becomes an expensive piece of equipment.
