how do i take the vocals out of the cdg's. do i need special equipment.

Most CDGs that have the vocals on the tracks usually have a second set of the same tracks without the vocals. If this is not the case, you may have a true multiplex disc, in which case you either need a player with the multiplex function OR you can just adjust the pan (balance) to the speaker that does not have vocals, as they locate the vocals on only one channel.

Are you talking about the backup vocals?  Most cdgs are vocal-less already except for back up & harmonies which you aren't going to be able to remove, unless it's the true multiplex as describe above.  
If you are talking about regular cd's, then it's completely dependant on the way the original recording was made - without going into the technical explanation, most karaoke machines have the vocal eliminator - and whether it will work or not again is depenant on each disc the way they were originally recorded, some work better than others.

Vocal eliminators on machines take out the frequency range that the vocals are most commonly at.    As stated, sometimes it works really well and others not so good.   If most of the instruments are at the same frequency range as the vocals, then they too will be deleted.   The better quality discs have everything on them that you heard on the radio, but the lead singer.

Actually it has to do phase cancellation.  Vocals are mostly recorded panned dead center - same info in both channels, what a vocal eliminator does is scans for like waveforms in both channels & reverse phases them - cancelling them out.  Leaving whatever left in tact.  Problem is quite often instruments are also recorded dead center such as bass guitar, kick drum, snare drum are the most common which also can be affected as well.  Which is the reason why some songs can sound really washed out when the vocal eliminator is engaged.  You also can end up with a ghost vocal - residual of the vocal effect used as these are generally panned differently.  Also if the recording is mono - a vocal eliminator will have no effect as everything is recorded the same on both channels.

It actually remove ALL frequencies at the center of the mix. Most vox are pan center and any instrument panned center will also be remove. It works by phase reversal. Any recording program that can do a phase reversal can be use to remove the center panned vox. The result in most case will not be good. There are other thing that need to be dealt with and some like efx will 'haunt' the result

Yep, and it will take a lot of the mid tones with it. Also, one word of advice. If you are doing vocal removal via software, make sure it's NOT in mp3 format. I understand that mp3 will process each channel separately and may have some differences between the left and right channels. That means that you will not have a perfectly recorded vocal information to both channels equally and may have residuals.

My players, both my Karaoke machine and my CAVS SP player for my pc, have the option of stereo, left and right - the vocals only come out of one side, but I can't remember which one, I usually just play around with it till I don't hear them any more.... I think its left, but don't quote me on that. It works really well if you have the right set up.  Drea

VL, you're not talking about a vocal eliminator.   You're talking about multiplex recordings.   The vocals are only on one side of the recording.

some of those players also had a "vocal eliminator", bd.

I'm thinking specifically of Panasonic, Pioneer, etc.

You could "one touch" a regular cd, and it would do the elimination like the current form out there that eliminates a percentage of the midrange of the song.

If it's a disk with one side vocal and 1 side music you could rip the song as an mp3+g onto your hard drive then open the mp3 with audacity find the vocal track delete it then copy the music track and replace it where the vocal track was then save it and remake the CDG with cdrwin. Simple, For 1 song hard for 1000 songs.
