Vocal Cancel is a feature that removes vocals from multiplex CD tracks. To be multiplexed, a 

disc must have the vocals coded to the right channel and the music coded to the left channel. When you 

select Vocal Cancel, the unit will remove the right channel (vocals) and split the left channel (music) to both 

sides. 

 Vocal Partner is a feature that removes vocals from multiplex CD tracks much in the same 

way as Vocal Cancel, but with an added "auto-pilot" function. The main difference is that Vocal Partner will 

only remove vocals as long as there is activity going through the microphone (singing). When you stop 

singing, the vocals automatically return.

 Vocal Reducer is a feature that removes vocals from standard non-multiplex CD tracks. To 

do this, the unit compares the audio on the left and right channels, and cancels out any signals that appear on 

both. Most currently recorded CD’s contain the vocal layer on both sides, however some may not, leading to 

varying results.

right channel (vocals) and split the left channel (music) to both sides.
