Karaoke Vocal Remover

No, all vocal removers are NOT ALIKE! We Invented the world's first Vocal EliminatorTM back in 1976. Even our early analog units outperform any alternatives! Far beyond every one else's simple L-R simple center channel elimination scheme the VE4 uses advanced and proprietary Digital Signal Processing (DSP) algorithms to remove more vocal with less loss of background instruments. We use two totally different methods to remove the voice. One of the methods actually reduces some (not all) of the reverberation that can remain on some recordings! We preserve almost all of the stereo content and do not go to mono the way a L-R scheme does.
You can actually create a simple free L-R eliminator without any equipment! Just connect the Left Plus (L+) and Right Plus (R+) speaker outputs on your amplifier to a single speaker and the center channel will be removed! You can use the balance control to fine tune the voice if it is off center. We never considered this acceptable and even our early analog units in the 70's and 80's fine tuned both level as well as time delay offsets between the two channels to maximize high frequency elimination. We also went to great lengths to restore the Bass signal as well. No one else (as far as we know) has even gone as far as we did in the 70's ! !
Today, with DSP, it's a totally different world! Now we will be the first to admit that improvements are not linear! Don't expect that if you throw 100x the effort and expense at a problem, you are going to get 100x the result!
