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.

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).
1
/
If you are connecting only one microphone, plug it into
MIC 1. If you are add-
ing a second microphone, plug it into
MIC 2.

The system has a built-in microphone
holder on the right side of the system.
To use the holder, pull it down from the
side of the system, and place the microphone in the holder’s grip.

32-1166.fm Page 8 Wednesday, November 17, 1999 4:51 PM
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

CONNECTING TO A TV
You can connect the CD/CDG karaoke
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.

LISTENING SAFELY
To protect your hearing, follow these
guidelines when you use headphones.
• Set the volume to the lowest setting
before yo u begin listening. After you
begin listening, adjust the volume to
a comfortable level.
• Do not listen at extremely high volume levels. Extended high-volume
listening can lead to permanent
hearing loss.
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a volume level that does not cause discomfort might still damage your
hearing.

CD/CDG CARE TIPS
Although a CD/CDG is very durable, you
should handle it with care. We recommend the following precautions:
• Keep the CD/CDG in its protective
case or sleeve when you are not
playing it.
• Keep the CD/CDG clean. Your local
RadioShack store sells a suitable
CD cleaner kit.
• Do not write on either side of the
CD/CDG, particularly the non-label
side.
• Do not store CD/CDGs in high-temperature, high-humidity locations.
They might warp.
• Keep CD/CDGs dry. A water drop
can act as a lens and affect the laser
beam’s focus.
• Always handle a CD/CDG by the
edges to avoid fingerprints. Fingerprints and scratches on the CD/
CDG’s surfac e can p revent the laser
beam from correctly reading the digital information.
• If a CD/CDG skips during play, it
might be scratched. Your local
RadioShack store sells a Scratch’n
Fix kit (Cat. No. 42-127) that might
stop the skip. Also, see “Troubleshooting” on Page 24.
• Press

TAPE CARE TIPS
Preventing Accidental Erasure
Most cassette tapes have two eraseprotection tabs — one for each side. To
protect a recording from accidentally being recorded over or erased, use a
screwdriver to remove one or both of the
cassette tape’s erase-protection tabs.
If you want to record on a tape side after
you have removed the erase-protection
tab, place a piece of strong plastic tape
over that side’s erase-protection hole.
Cut off excess plastic tape
Notes:
• Be sure you cover only the hole that
was originally covered by the eraseprotection tab.
• Removing the erase-protection tabs
does not prevent a bulk eraser from
erasing a cassette tape.
Erasing a Cassette Tape
If you no longer want a recording, you
can record over it or erase it.
To erase a previously recorded section
of a tape, simply record over it.
To erase the entire cassette tape, r ecord
silence by setting
to TAPE and recording with no tape in
TAPE 2.
You can quickly erase both sides of a
cassette tape using a bulk tape eraser
(such as Cat. No. 44-232), av ailable at
your local RadioShack store.
FUNCTION SELECTOR
Cleaning the Tape-Handling
Parts
Dirt, dust or particles of the tape's coat ing can accumulate on the tape heads
and other parts that the tape touches.
This can greatly reduce the performance
of the cassette player. After every 20
hours of tape player operation, use a
cassette deck cleaning kit (Cat. No. 44-
1202) or follow these steps to c lean the
tape-handling parts.
1. Disconnect the AC power cord.
2. Open the cassette compartment
doors on TAPE 1 and TAP E 2.
3. Press
TAPE 2 to expose the tape-handling
parts.

4. Use a cotton swab dipped in denatured alcohol or tape head cleaning
solution to clean the record/play
heads, pinch rollers, capstans, tape
guides, and erase heads.
5. When you finish cleaning, press
STOP/EJECT on TAPE 1 and
TAPE 2 and close the cassette compartment doors. Then reconne ct AC
power.
Your local RadioShack store sells a full
line of cassette deck cleaning supplies.
Restoring Tape Tension and
Sound Quality
After you play a cassette tape several
times, the tape might become tightly
wound on the reels. This can cause
playback sound quality to deteriorate.
To restore the sound quality, fastforward the tape from the beginning to
the end of one side, then completely rewind it. Then loosen the tape reels by
gently tapping each side of the cassette’s outer shell on a flat surface.
Caution:
cassette when tapping it. Do not touch
the exposed tape or allow any sharp objects near the cassette.

RECORDING A CASSETTE TAPE
You can become a recording star! The
system lets you record your voice on a
blank or reusable tape as you sing along
with a special karaoke cassette tape,
video tape, CD/CDG or other audio
source. You can also record from an external audio source, or dub from one
cassette tape to another.
Recording Tips:
• Tape quality greatly affects the quality of the recording. We recommend
RadioShack Supertape Extended
Range or Low-Noise Type 1 tape.
We do not recommend long-play
cassette tapes, such as C-120s,
because they are thin and can ea sily
tangle in the cassette mechanism.
For low-noise, wide-range recordings, use normal-bias tape.
• Before recording, be sure the tape
you are using has its eraseprotection tabs in place. See “Preventing Accidental Erasure” on
Page 19.
• Recording automatically stops when
the tape in TAPE 1 reaches the end.
To record on the other side, turn
over the tape.
