FEATURES
Your Optimus CDG Karaoke System is
one of the most versatile karaoke systems available. It lets you be the “star”
as you sing along with your favorite recordings on a CD, a CDG (a compact
disc with a graphic track), a cassette
tape, or a video tape, and hear your
voice with the music through the powerful built-in speaker.
The karaoke system’s CDG capability is
the latest advancement in karaoke technology. It lets you connect the k araoke
system to a TV or monitor and read the
lyrics of your favorite tunes as they scroll
by in front of a still video graphic, such
as a picture or drawing related to the
music.
You can sing along without video graphics using special karaoke audio cassette
tapes (such as the one we have included to get you started) that let you balance the volume of the original singer’s
voice and the music tracks. Or, you can
sing along with a regular prerecorded
cassette tape or CD (not supplied).
You can also connect another audio
source to the karaoke system, such as a
stereo VCR, and play a karaoke video
cassette (not supplied).
Note:
Additional karaoke CDs, audio
cassettes, and video cassettes are
available by special order through your
local RadioShack store.
Your karaoke system’s features include:
Front Loading CD/CDG Player —
you play regular or karaoke CDs, or special CDGs so you can experience digital
images — the latest in karaoke fun!
Plus, the player’s 16 bit D/A converter
(digital-to-analog conversion circuitry
which accurately reproduces all sound
levels with virtually no distortion) and 8
times oversampling produce high quality
sound.
Dual-Cassette Decks
two cassette tapes in a row, dub from
one tape to another, or sing with one
tape while recording on the other.
8-Watt Per Channel Amp
singalong and listen through the
karaoke system’s 5-inch woofer and 2inch tweeter.

hall effect.

pitch.

CONNECTIONS
Caution:
To avoid electrical shock, do
not connect the system to AC power until all other connections are complete.
CONNECTING
MICROPHONES
The system has two microphone jacks
so you can use the supplied microphone
to sing along to your favorite recordings,
and connect an additional microphone
(not supplied) for duets or lead and
background vocals.
For the best performance, the additional
microphone should be a unidirectional
600-ohm dynamic microphone with a
inch (6.35-mm) plug and an ON/OFF
switch. Your local RadioShack store has
a wide selection of microphones.
Before you connect a microphone, always turn
MIC VOL 1 to MIN on MIC 1,
(and MIC VOL 2 if you are connecting an
additional microphone).

CONNECTING OTHER
AUDIO COMPONENTS
You can connect an external audio
source or component to the karaoke
system, so you can sing along with other
audio formats or videos, or hear the
karaoke’s sound from another speaker
or a PA system. To make the connection, you need optional audio patch cables (such as Cat. No. 42-2352).
Note:
If your audio source does not
have AUX OUT R and L jacks, but has
only a headphone or line out jack (such
as on a portable tape or CD player), use
a shielded Y-adapter cord with phono
jacks on each end (such as Cat. No. 42-
2475). Connect the single-plug end to
the audio source’s headphone or line
out jack, and connect the other end’s
two phono plugs to the system’s
R
and L jacks.
AUX IN
Connecting an External Audio
Source for Input
You can connect another audio source,
such as a stereo VCR or another CD
player, so you can sing along with the
audio source’s sound. Connect the
source’s stereo audio output jacks to the
system’s
AUX IN R and L jacks.
Connecting an External Audio
Component for Output
You can broadcast the karaoke system’s sound through an external audio
component such as a PA system amplifier. Connect the external audio component’s audio input jacks to the karaoke
system’s
AUX OUT R and L jacks.
Connecting an External
Speaker
You can connect an external 8 to15-watt
stereo speaker with 4-8 ohm impedance
to the system for a stereo effect. Plug
the speaker’s phono plug into
SPEAKER
tem.

system to a TV or monitor and see the
words and images produced by a special karaoke video cassette or CD/CDG.
Plug one end of the supplied cable into
VIDEO OUT and the other end into your
TV’s video in jack.
Note
: For TVs that do not have an a udio/video input jack, use a video RF
modulator (such as Cat. No. 15-1283).
Connect the RF modulator to
OUT
and to the TV’s 75-Ohm VHF input
terminal, following the instructions in the
modulator’s owner’s manual.
