r.cherry Posted May 28, 2005 Share Posted May 28, 2005 i am putting a few lp's onto cd for a friend. my desktop is apart for upgrades currently so i am using my laptop. the sound card is Avance AC97. There is no line in so i am using the mic in from my receiver. I can't seem to keep the levels low enough to prevent overmodulation. is it possible to record directly from the tt to the hard drive by passing the receiver? and if i can do that will it help the problem?

3dzapper Posted May 28, 2005 Share Posted May 28, 2005 You would loose the RIAA equalization circuit. Rick Quote Link to comment Share on other sites More sharing options...

Marvel Posted May 28, 2005 Share Posted May 28, 2005 The preamp out of your reciever is at a level that is too high for the mic imput to handle. Yes, even the SB may be better than the built in audio chip on the laptop, but not necessarily. If you are in a hurry, you can take some resistors and pad the level down for the mic input. This can actually work quite well. You need to drop the level about 40db. That would probably get you into a range that you could then adjust more easily. Do you know the mic. input impedance? I can generalize, and you can get reasonably acceptable results with the following, but details would help. in ----R1--------R2------ out / / R3 / GND (shield) R1= 50k ohms R2= 1.8K ohms R3= 200 ohms 1/4 watt will work fine. This a 40 db pad for one channel. You would have to wire two up (left and right), so you only need 6 resistors and the cable. Radio Shack parts would work fine. Get a 1/8" stereo to roc cable and have at it. This is around 2K output impedance, which may still be too high for the mic input, but a lot of cheap sound cards have a pretty high in;ut impedance. This is approximate, but should work okay. Marvel Quote Link to comment Share on other sites More sharing options...

You need it in there. Quote Link to comment Share on other sites More sharing options...
DrWho Posted May 28, 2005 Share Posted May 28, 2005 First, you should just turn the line in volume way down in your software settings and make sure you don't have mic boost enabled. (sometimes you might have to click on special things to be able to fully control the mic input on your pc). Quote Link to comment Share on other sites More sharing options...

A program I use is called Magix audio cleaning lab. $40 at best buy...you simply tell it that you are coming direct from your tt and it automatically compensates...works pretty slick...

scotbuck Posted May 29, 2005 Share Posted May 29, 2005 Greetings, You can get some very inexpensive phono preamps at: http://www.audioreplay.net/index.html These will let you go from the turntable into your PC. The higher-end models (still only about $75) have a volume control that will let you attenuate the input signal. Hope this helps... Take care, Scott Quote Link to comment Share on other sites More sharing options...
