ENGLISH
In addition to all of the terminology associated with consumer electronics products, a few
additional terms are used almost exclusively in karaoke. These terms are meant to familiarize
you with the world of Karaoke. The features listed below may not necessarily pertain to the
particular model Singing Machine that you have. The following are some brief explanations of
karaoke terms:
Echo:
Echo adds depth and resonance to a singer’s voice without affecting the music. This echo is
produced by creating minor controlled feedback in the singer’s voice.
THE SINGING MACHINE KARAOKE GLOSSARY OF TERMS
M ultiplex:
Our multiplex recordings contain 2 copies of the same song. One version is a stereo recording
of the song without the lead singer. The second version is recorded with the music and
background vocals on the left channel and the lead singer recorded on the right channel. This
‘split track’ recording allows you to control the volume of the lead singer by adjusting the
balance control. You can sing a duet with the lead singer or use the lead singer as a guide as
you learn the song, gradually fading them out with the balance control until you are able to sing
the song on your own.
Auto Voice Control (A.V.C.):
W hen the AVC function is activated, the vocals on a multiplex recording are eliminated as soon
as the singer begins singing into the microphone. W hen the singer stops singing, the vocals on
the multiplex recording are automatically re-activated. This useful function is used primarily
during practice sessions while a singer is learning a song. Please note that the AVC function
only works with multiplex recording and not with standard audio recordings.
Pitch Control:
This function controls pitch of music by controlling the speed at which a cassette tape plays
back. By increasing the speed of the tape, the music sounds higher (sharp). By slowing the tape
speed, the music sounds lower (flat).
Key Controller:
Key Controller changes the key of the CD/CDG music (+ or - steps) to adjust to the singer’s
voic e.
CDG:
This is an acronym for Compact Disc plus Graphics. You will also see variations CD+G, and
CD+Graphics. This is a regular audio CD with information stored on a data track simultaneous to
music. In laymen’s terms, CDG has a video output for simple graphics (not full motion video).
In the case of karaoke, the graphics function is used to store song lyrics, and display the lyrics
in synch with music. In most cases, CDG software displays lyrics which change color as they
are to be sung. A regular television is all that is required to display CDG lyrics.
NOTE - CDG is a particular type of compact disc encoding system that is different from VCD or
DVD. Your Singing Machine can decode standard audio compact discs and CDG discs. It will not
read VCD or DVD encoded discs.
Standard audio discs and cassette tapes will not display lyrics on your TV. Audio CDs do not
contain the software necessary to display lyrics.
