THE KARAOKE MACHINE (GLOSSARY OF TERMS)
Following are some brief descriptions of karaoke terms you may need:
Echo:
By adding some minor feedback to your voice the Echo feature adds depth and
resonance to a singer's voice. Echo affects only your voice and not the music. It
will make you sound like you are singing in a big concert hall.
Multiplex:
This karaoke system is capable of playing Multiplex CD+G Karaoke discs.
Multiplex Karaoke discs feature two mono versions of the same recording on left
and right channels. The right channel features a mono version of the song with the
lead vocals pre-recorded. The left channel features the same song, without the
lead vocals recorded.
Auto Voice Control (A.V.C.):
This is short for "Automatic Vocal Control". When the AVC knob on the front panel
of the player is turned clockwise, the AVC function is activated. AVC is used to
eliminate the singer's vocals from specially made Multiplex CD+G karaoke discs.
Once the AVC is activated, as you sing into the microphone, the pre-recorded
vocals are eliminated and replaced with your singing voice. Set the AVC to a lower
setting, and you'll be able to hear the pre-recorded vocals in low volume as well as
your own singing voice. Set the AVC to maximum and as you sing into the
microphone, the pre-recorded lead vocals will be completely eliminated, and only
your own singing voice will be heard.
NOTE: The AVC controls is only functional with specific Multiplex CD+G Karaoke
Discs. AVC will not eliminate the vocals from standard music CDs, and will not
function when playing standard Karaoke CD+G discs, such as the disc included
with this system.
CD+G:
This is short for Compact Disc plus Graphics. This is a regular audio CD with the
lyrics stored in a data track. While your karaoke player will play regular audio CDs
they will not have the background data track that will allow the lyrics to be
displayed.
