FEATURES
Your Optimus Karaoke lets you be the
star as you sing along with your favorite
recordings. To hear your voice along
with the music through a speaker, simply connect the karaoke between an external music source (such as a CD
player) and your amplifier/receiver.
The karaoke works with stereo recordings so there are no special karaoke
tapes to buy.
Your karaoke system’s features include:
Voice Canceller
— lets you reduce the
volume of the prerecorded singer’s
voice as you sing with the music.
Supplied Microphone
— lets you im-
mediately sing along with the music.
Dual Microphone Jacks
— let you use
the supplied microphone and an optional microphone simultaneously to sing
duets or for lead and background vocals.
Separate Microphone Volume Con-
— let you adjust the volume of
trols
your duet partner or backgr ound singer
separately.

your system from internal batteries or
AC power (with an optional adapter).
