Does anyone know what the recommended line input voltage is for the tda7498e? I've read the datasheet a couple times but most of what I'm reading is above my head and it isn't clearly stated.
Maybe first tell us your problem.
I don't think you are designing an amp if a datasheet is too much information for you. So you refer to some existing object and problem? Input voltage has something to do with an amps gain. Chinese versions of such chip amps usually have too much gain, that is because they mostly don't understand an audio concept deep enough. They think "much loud very fast" gives their product an advantage in sales, as it is subjectively fellt to be stronger than a board of reasonable gain. Cheating as a live style doesn't result in good products.
So maybe you can elaborate?

I have a Sanwu board configured with 29.6db of gain which is the lowest it goes without changing smd resistors. I was testing it's output with an oscilloscope the other day and want to make sure I'm not going to give it too much voltage and screw something up. I started out with around a 300mv 1khz signal and got pretty dismal results. I ended my tests with a 1.1v 1khz signal and measured 26v rms right before clipping.
