-- my integrated sound card...


Posted by xstalkrx on Oct-19-2005 23:37:

my integrated sound card...

My computer has an intergrated sound card. It DOES have a line in port. Can I record from my turntables with this computer?

My phono ports are used to go from my turntables to my mixer. What are the line ports used for? There are no cables connected in the back of my line ports.

My master output goes from mixer to receiver. There are no extra out ports.

What needs to happen in order for me to record? I only have one line in port on the back of my computer.

So since I only have one line in port...I will not be able to record a proper mix?

I would need a second sound card to do this?

If I buy the mini jack to RCA converter like you mentioned...it would seem to me that I could mix using both channels and be able to record a set?

yes you can record a set from your turntables. I have one sound card and I do it almost daily.


Posted by Orbital32 on Oct-20-2005 01:52:

you just need a RCA to mini jack adaptor. also a program to record.


Posted by xstalkrx on Oct-20-2005 01:54:

and i will need two of these....correct?

I already get buzzing in speakers as is. where does the ground loop eliminator or whatever get put in?


Posted by Orbital32 on Oct-20-2005 01:55:

yeah, but actuall you may need a female end RCA jacks depending on the cable you are using.


Posted by Orbital32 on Oct-20-2005 01:57:

get the ground loop at car audio shop.


Posted by xstalkrx on Oct-20-2005 02:03:

im basically using that exact cable you see there.


Posted by xstalkrx on Oct-20-2005 03:16:

My receiver is currently set on "Auxilary". Will there be any need to change this setting while recording?

i hate electronics :/

so are there some nice laptops out there that have external sound cards to eliminate the need for this adapter bs?

Yes, but not directly.

The line-in ports are used for line-level equipment, like CD players and cassette players.

Turntable to mixer to computer and receiver, using 2 single-RCA-plug-to-dual-RCA-jack-Y-cables on the mixer, one for each channel to split the output on the mixer to the computer's line-in port and to the receiver's Aux-in port.
Radio Shack Y-cable here

Connect a ground loop isolator between the mixer and the computer, using the y-cables. The ground loop isolator from Radio Shack should come with the extra connectors you need for the computer's line-in port.
Radio Shack Ground Loop Isolator with everything you need here

You need a recording program. One line-in port is all you need.

Not sure what you mean by both channels on your mixer. Is that left channel and right channel you're talking about? There is only one output from your mixer anyways.

The ground loop isolator is a stereo RCA cable (2 channels).

Get 2 (two) Y-cables to split the master out on the mixer. One for left, one for right.

ya i was confused there for a sec. ok i am picturing how it all works now.

any experience with these ground loop isolators? do they block out all humming?


Posted by Orbital32 on Oct-21-2005 00:09:

try googling some of these questions. I'm sure your results will be alot faster then you posting the question.

They do reduce the humming quite a bit. You'd have to judge that for yourself. With the Y-cable though, you'll also end up with a direct connection from your receiver to your computer. That may introduce some hum too at either end. It's better if you had a master out and a tape out on your mixer. Then you wouldn't need the Y-cables.


Posted by xstalkrx on Oct-21-2005 03:20:

I'm just going to buy a new mixer to solve my master out problem. Probably about time i had a three band EQ anyways. :/

I was looking at the Pioneer DJM-300 as my next mixer? Any feedback on this mixer?

A employee at Guitar Center said that an integrated sound card is going to make my recordings sound like shit regardless of any ground loop isolator i use. He says the humming has nothing to do with any ground. He says I will need a decent sound card before getting a clean recording.

Thoughts on this?


Posted by Orbital32 on Oct-21-2005 05:00:

well tell that guy that i said that he's a fucking idiot. Why do i have a ground loop isolator on my mixer going to my comp? for the same reason i have on one my car. It takes the humming out....like its suppose too.


Posted by xstalkrx on Oct-21-2005 06:05:

What kind of computer do you have orbital? What are the specs? I have a 2.7 ghz processor if that has anything to do with recording...and its a cheap emachines comp.


Posted by trancecadet on Oct-21-2005 15:37:

how have you wired up your ground loop for the laptop Orbital?

@ xstalkrx... CPU speed means nothing really when recording. I used to use an old K6-2 450 to record my sets.. But a good CPU helps for production.. Your PC is an Intel P4 or Celeron.. Hopefully a P4 since they are better. No big deal though

oh and i feel like braggin.. I have.. Intel 1.4ghz lappy, AMD 1.5 @ 2.2ghz watercooled (almost complete), AMD 1.4 @ 1.8ghz, Intel Dual P3 550's plus another 2 Intel P4's half built.. I work for a PC repair company

no hes right in a way but he hasnt explained it very well though.

if your mixer doesnt have an onboard preamp then you need to use a DI box or external preamp between the turntable/mixer and in the input on your soundcard. otherwise the signal wont be hot enough when recording and you'll find you have to amp up the signal loads post recording which will increase the noise floor as well as peak volume. this often results in audible humming.

even if that isnt taken into account what kind of analogue to digital converters are there on an onboard soundcard?! you are never going to get 24 bit/96 khz recordings from a mini TRS jack.

an m-audio audiophile 24/96 is pretty cheap, has 2 analogue RCA inputs and it can record at 24 bit and 96 khz. the A/D converters arent too shabby either. one of those would solve all of your problems pretty much.

but yea. i fail to see how recording through a mini TRS line input is ever going to get you the kind of bit for bit recording you are going to get with a proper 24/96 recording interface...

Ok so that audiophile product is like an external sound card? I'll plug my 1/8 jack into this audiophile and then the audiophile connects using USB ports? And I get very clean recordings without having to use ground loop isolators? Or are the ground loop isolators still recommended?

Well after looking at the pics it only has 1/4 inch jacks.

i have a 933mhz PIII. but like it was stated CPU means nothing to the soundcard. I have 2 different sound cards attached, one is a Hercules GTXP and the other is a Hercules DJ console. I have the RCA jacks coming from DN-x1500 mixer to the isolator to my RCA inputs of my soundcards. The only i was able to get rid of the hum was through the isolator, no volume, adjusment of the location fo the cords, or anything else was able to take it out. What i might do, since the Denon Dn-x1500 has a co-ax digital out, that would make it clearer...and since the DJ console everyting at 48Khz @ 24bit, the sound should come out great!


Posted by trancecadet on Oct-22-2005 01:01:

I have a GTXP.. brilliant soundcards..


Posted by xstalkrx on Oct-22-2005 07:50:

so the m-audio audiophile 24/96 is like an external sound card?
