Multiplex is a term used to describe the separation of the background music
from the vocal track. By recording the background music on the left channel
and the vocal track on the right, it is possible to mix the two to gain a vocal
version of a song, or play just the background music and you would normally
expect to hear on a karaoke track.
USING THE AVC (AUTO VOCAL CUT) CONTROL
Sometimes, when singing karaoke it is easy to loose your place or become
embarrassed. When playing the vocal track on a multiplex disc, it is possible
to replace the singers voice with your own as soon as you start singing
into the microphone by using the AVC control (8, page 4). If you then
subsequently stop singing, the singer on the recording will resume to pick
up where you left off.
It is also possible to adjust the amount the singers voice is reduced so that
it does not leave all of the singing to you..
Turning the AVC control clockwise will increase the amount the singers
voice is reduced. Turning the AVC control completed anti-clockwise to the
MIN position will turn this feature off resulting in the singers voice on the
track being at full volume along side your own singing voice.
The setting of this control is down to user preference and should be adjusted
until the desired level is achieved.
USING THE AUDIO BUTTON
You can use the AUDIO button on the front panel (2, page 4) to manually
select which channel of sound you wish to hear when playing a multiplex
disc. You can select MONO L (Left channel only), MONO R (Right channel
only - typical vocal channel) or STEREO (Both left and right channels).
