Do not operate the appliance if the power cable, the plug

•
or the device itself are damaged. Arrange for defective
power cables and plugs to be repaired or exchanged as
soon as possible by Customer Services.
You must not open the device housing or attempt to repair

•
the device yourself. There are no user-serviceable elements

inside. Should you do so, device safety can no longer be

assured and the warranty will become void.

directly into an open CD tray The invisible laser beam
could damage your eyes.

 CAUTION!

Information on surge voltage (EFT / rapid electrical
transition process) and Electrostatic discharge:

In the case of a malfunction due to rapid electrical transition
(surge voltage) or electrostatic discharge the product must
be reset (it may be necessary to disconnect the power source
and then reconnect it) to restore normal operation.

Note: A case of electrostatic discharge occurs if one walks
with plastic-soled shoes over a carpet that also contains ele­ments of plastic. Through the friction of the shoe soles on the
carpet a charge is created in the body which discharges
itself as soon as one touches an electricity conducting object,
such as for example a door knob or the bodywork of a motor
vehicle. Thereby, it is sucient to approach the conductor to
within only a few cm. Direct contact is not required to eect a

discharge. The charge can also reduce itself over an electri­cal arc. A discharge is thus also possible through plastic hous-

ing components.

Note: This device is equipped with non-slip rubber pads.
As upper surfaces can be made of various materials and
are treated with various cleaning materials, it cannot be
completely excluded that some of these materials contain
components that could attack and soften the rubber pads.

If possible place an anti-slip material under the pads of the

device.

Riskofsuocation!

Do not leave packaging material lying unattended. Plastic •

foils and bags and pieces of styropor etc. are not toys, they

can be dangerous for small children.

Observe copyright laws

When recording CDs, pay heed to the laws regarding copy­right that are applicable in the country in which the device is

being used.

Positioning the device

Take the karaoke machine and all accessories out of the >
packaging.

Remove all transportation fasteners and tapes/foils.

>

Place the karaoke machine on a level and horizontal sur-

>

face. Position the karaoke machine in such a way that the

CD tray cover can be fully opened.

Setting the sound quality

Echo effect

Vocal music can be modied through an Echo eect. The
Echo eect can be increased by turning the controller ECHO
clockwise in the direction MAX, and reduced by turning it
anti-clockwise in the direction MIN.

Balance

The left and right channels are played back simultaneously
over the built in loudspeakers. Playback of both microphones
takes place over the right channel.

Through adjustment of the controller BAL you can modify the
relationship between the music and the microphone-vocal.
Turning it in the direction R reduces the music volume level
in relationship to the microphone-vocal level. Turning it in
the direction L reduces the microphone-vocal level.

In headphone operation a clear modication takes place
between the left and right channels, and vice versa.

Auto Voice Control

In the playback of CDGs (see CD operation/CD+G) the music
on the CD is blended out automatically as soon as someone
sings into the microphone.When the singing into the micro­phone stops, the music is automatically blended back in.Using
the controller AVC you can, in combination with the controller
BAL, balance out the proportions of the playback and the vol­ume level of the microphone.

X-Bass

Switching on the X-Bass function amplies the sound of the
basses. Incorporate or eliminate this function by pressing the
switch X-BASS on or o.

- 4 -

Pitch

When playing back a cassette, you can increase or reduce
the playback speed and thus tune it in to the voice. For this,
turn the controller PITCH in the direction MIN resp. MAX.

Using headphones

On the - output of the karaoke machine you can connect a
headphone with a 3.5 mm jack plug (not supplied). When you
have connected the headphones, the built-in loudspeaker is
disconnected and you will only hear sound through the head-

phones.

Important! Listening to music with headphones for

long periods and at high sound volume levels can
lead to hearing damage!

CD Operation

The device plays audio CDs (CD-A) and CD+G.Not only
commercially pressed but also CD-R blanks "burnt" on a home
computer are supported. Because of the many dierent kinds
of blank discs, computer types, operating systems, burning
software and burning processes we are not able to guarantee
that every "burnt" disc will playback faultlessly. Not always
readable are CDs that have been produced for the commer­cial eld.

Interaction with CDs

Every CD is enclosed within a hard-wearing plastic coating
that protects it from external inuences. Nonetheless, you
must still always protect the CD against soiling and scratches.
CD players can balance out minor damage on the CD. Large
scratches or other damages can lead to "hangers" or similar
malfunctions.
For details of the correct interaction with CDs, take heed of
the notices on the CD sleeve!

CD+G

CD+G (CD + Graphics, also CDG) is an Audio CD which
contains additional data, such as song texts and/or images,
that is displayed on the screen simultaneously with the music.

Audio CDs with copy protection

As one can learn from the press, the music industry has
developed various copy protection processes to defend

itself from pirate copies. Unfortunately, not all companies

have yet agreed on a universal standard, thus they continually

develop new processes or modify the existing ones. These
newly released Audio CDs then no longer conform to the
normal Audio CD Standard, and it therefore becomes dicult
for the manufacturers of CD players to ensure that their de­vices can assimilate all of the latest copy protection methods.

In individual cases it can even happen that a few copy-pro­tected Audio CDs cannot be played back. To eliminate the

possibility of a defect on the device, please test it using an

older Audio CD without copy protection.
The trade press advises returning copy-protected CDs back
to the trade if they cause playback problems, or to ask for an
Audio CD without copy protection.

Insertion and playback of CDs

Operating the cassette player/recorder

The correct cassette

Exclusively suitable are Audio Compact Cassettes of the

•
type Normal (FE Tape).
Ideally, utilise cassettes with a length of 60 or 90 minutes.

•
Longer tapes are typically made of thinner material and
are more likely to be caught up in the tape transport
mechanism.
Always store cassettes in their cases. Otherwise, the lightly

•
magnetic tape attracts dust particles from the air and these
can then become deposited on the tape heads during
playback.
Protect cassettes from strong magnetic elds and high

•
temperatures. Do not store them close to television sets,
loudspeakers and the heating. The tape could be erased,
stick together or tear.

Insertion and playback of cassettes

Switch the device on and select the operating mode. For

>

this, slide the switch FUNCTION into the position "TAPE".
To open the cassette compartment, press the button

> .

Insert the cassette with the open side facing downwards. >
Gently close the cassette compartment.

>

Start playback with the button

> 4.

Starting, Stopping, Interrupting, Rewinding

Important!

To take care of both the mechanics in the drive mechanism and
the tape material itself, do not switch directly from forward or
reverse rewind into playback, instead, rst stop the tape with

the button

.

Interrupting playback: Press the button > ; twice.
Continue playback: Press the button

> ; once again.

Reverse rewinding: Press button

> 7. The cassette stops

automatically at the tape start, but the drive mechanism
is not switched o.

Forward rewinding: Press button

> 8. The cassette stops

automatically at the tape end, but the drive mechanism is
not switched o.

Stop playback: Press button

> .

Note:

On playback and record the cassette stops at the end of the
tape and automatically switches the drive mechanism o.

Preparation for recording

Recording is only possible if the write
protect notches of the cassette to be
recorded on are closed.

With new cassttes the write protect

•

notches are closed.
After the recording you can protect the

•

cassette against unintentional re-record-

ing by carefully breaking out the tongues
in the write protect notches with a sharp
object (screwdriver, naille).
Should you want to make a recording on

•
a write protected cassette, simply cover
the open write protect notches with a

piece of adhesive tape. Ensure that the
adhesive tape cannot loosen itself; if it
does, it could get caught up

in the tape transport mechanism.

At the start of the tape there is always a small piece of leader
tape. It serves to protect the tape against tearing or stretching
after fast rewinds. Recording is not possible on this piece of

tape.

If necessary, close the write protect notches on the

>

cassette.

Inserting a cassette

How you proceed next is dened in a section below,
called "Recording Karaoke on a cassette".

Karaoke

You can sing along to a CD, a CD+G or a cassette.

Karaoke with a CD+G

Connect a microphone and switch the device on.

>

Slide the switch FUNCTION into the position "CDG".

>

If you use the integrated screen:

>

Slide the switch MONITOR into the position "CDG". The
song texts contained on the CD+G will be shown on the
monitor. Thereby, the texts that have already run through
will be shown in a dierent grey-tone than the texts that

still have to be sung.

If you have connected a television set to your karaoke
machine:
Slide the switch VIDEO OUT into the position "CDG".
