Chipamp is too quiet.

raypalmer · 29th January 2009, 04:37 PM

So I finally got my psu figured out. Bigups to Audio1st, Peter Daniel, Nuuk and AndrewT.

But now my GC is wayyyy too quiet.

My first question has to be: Does the wattage rating of a resistor matter? Intead of .5w some of my resistors are 2w. Is that an issue?

Hi Ray.
The wattage won't affect the volume.
I thought you were using one of Peters kits? Any chance of a photo?

Are you using a volume control Ray? Is that wired up the right way?

can you take a picture or your board? maybe a wrong resistor was used (im thinking the input or feedback resistor).

I was reading back to your post in the PSU beginner's guide thread, and you stated you had 0.5V on your output. If you had no input connected, that is way too high, probably the reason for your turn off thump. You should have no more than 0.1V (100mV) on your output, or you risk damaging your speakers. You said you got things figured out, was this problem solved too?
