Looking for a budget amp for a desktop

post #1 of 11
Thread Starter 

Budget: ~$50

 

I want to plug the RCA out on my tv into my sound card's line-in to use as a mixer but the signal is really weak even with the line-in all the way up (the rca cable is 15 feet), so I just need something to boost the signal before it enters my sound card. I don't need anything fancy, just enough to give me a good volume range.

 

Thanks

for that price it is tough. I would look on ebay at some xduoo stuff or topping etc

So I got the Rolls and it works great by itself (without plugging it into my soundcard) and amplifies the signal quite nicely, but when I plug it into the line-in all I get is static and a really distorted signal.

 

Is this gonna be true for all amps? Do I need to buy a completely different device to make this work?

And the reason why I don't want to turn up my windows volume slider is because I'd have to turn down the sliders on everything else, some of which are already really low (10), so I don't want to completely ruin the range.

Would I need a pre-amp for this? I don't know what I'm talking about.

Should I post this on a different forum?

What soundcard do you have? You should be plugging the amp into a line-out not a line-in.

If I plug it into the line-out then I'm just amping everything in the windows mixer, when I only want to amp the line-in, and I can't just turn the others down because some of them are literally on 1 or 2 already.

You could be dealing with an impedance mis-match of some sort.  I had that problem when I was playing around with a Shure SM57... I was trying to plug it into a receiver or something, with no "real" mic preamp.

 

My brother had this problem with either an FM tuner or CD player/deck with a really low line output he used a device similar to the one in your last post to boost the line level.
