USING THE AUDIO MIXER
TO ACTIVATE THE PITCH CONTROL
The KL-1 has been designed with a comprehensive audio mixer to allow complete control over your performance.
The mixer has 3 main sections:
1) Music selector switch
2) Microphone section
3) Multiplex control for use with CD+Graphics discs recorded in multiplex format
4) Main audio output controls
Each of these sections are explained in detail over the next few chapters.
12
It is necessary to select which music input source you require. The Music
Selector rotary knob (12, page 3) allows the choice between CD, Tape and
AUX inputs.
USING THE INPUT SELECTOR SWITCH
UNDERSTANDING AND USING THE MIC SECTION
The mic mixer has been designed to allow 2 singers independant control
of the levels of their microphones.
Plug the mic to be used into the mic socket 1 or 2, ensure that the switch
on the body of the mic is pushed up to switch the mic on.
It will be necessary to have the master volume control (20, page 3) set up
to a reasonable level.
Mic level 1 can be increased by turning the Mic Level 1 knob (29, page
3) clockwise until the desired mic level is achieved. Similarly the same
procedure applis to mic 2.
The depth of echo which is applied to both mics can be adjusted by
turning the mic echo control (28, page 3) clockwise to increase the depth
of echo, or anti clockwise to reduce down to zero, as required.
The KL-1 is also tted with bass and treble controls for the microphones
which are independant from the main music tone controls. Turn the bass
and treble control knobs (26, 27 page 3) clockwise to increase the amount
of bass or treble, or anticlockwise to reduce it. The normal listening
position for bass and treble is straight up at 12 o’clock, however your
desired settings are a matter of personal listening tastes.
Take care not to turn mic levels too high when in close proximity to the
loudspeakers as feedback may occur. To reduce feedback, reduce the mic
level, or move further away from the loudspeakers.
13
The KL-1 has been designed to operate with both normal stereo CD discs,
and multiplex karaoke discs.
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 of a sterero CD or tape, 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 backround music as you would normally expect to hear on a karaoke
track.
The KL-1 is tted with comprehensive controls which allow you to make
best use of both stereo or multiplex discs or tapes.
For playing normal stereo recordings ensure that the stereo/mono switch
(35, page 3) is set to stereo. This will allow you to enjoy the full advantage
of the stereo image provided by this format.
When playing multiplex discs or tapes set the stereo/mono switch (35,
page 3) to the right into mono.
This will then combine the left and right channels to effectively give you a
full vocal version of that track. At this point you have two opions:
1) Activate auto vocal cut which will reduce the vocal content of the track
when you sing into the microphone.
2) Use the balance control which will allow a manual mix between the
background and vocal content of the multiplex format.
UNDERSTANDING AND USING THE
MULTIPLEX CONTROL
AUTO VOCAL CUT FUNCTION
14
Sometimes when singing karaoke it is easy to lose your place or become
embarrased. When using multiplex discs and the auto vocal cut feature,
it is possible to replace the singers voice with your own when you start
singing into the micrphone. If you then subsequently stop singing the
singer on the recording will resume to pick up from 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.
To operate this control ensure that the balance/vocal mix control (23, Page
3) is at the 12 o’clock position.
The control Auto Vocal cut (24, page 3), will vary the amount the vocals
are reduced, the more that it is turned clockwise.Turning it completely
anticlockwise will turn this feature off. The setting of this control is down to
preference and can be adjusted until the desired setting is acheived.
It is possible to mix the amount of vocals in the track manually by using
the Balance / vocal mix control (23, page 3).
To use this feature ensure that the auto vocal cut function is turned
completely anticlockwise and is off.
Ensuring that the Balance/ vocal mix control knob is at 12 o’clock, you will
hear a mix of both vocals and background music.
By turning the balance / vocal mix control knob anticlockwise you will
reduce the amount of vocals in the song to zero, once the control knob is
completely anticlockwise.
By turning the Balance / vocal mix control knob clockwise you will reduce
the amount of background music in the song to zero, once the control
knob is completely clockwise.
This control can be adjusted until your desired listening setting is
achieved.
BALANCE / VOCAL MIX FUNCTION
The last section of the KL-1 mixer is the main output controls.
These are
1) Bass
2) Treble
3) Master volume.
UNDERSTANDING THE MAIN AUDIO
OUTPUT CONTROLS
The main output controls
15
The bass and treble controls (21, 22 Page 3) work independantly from the
microphone bass and treble controls, and apply tone adjustment to the
music content only.
Adjust these by turning anticlockwise to cut the amount of bass or treble
applied to the music, or conversly clockwise to boost the amount of bass
or treble.
Note: It is possible to cause longterm damage to the speakers or other
equipment connected to the KL-1, if excessive volumes are maintained
with both bass and treble controls set to maximum.
The master volume control knob (20, page 3) is effective on both the
music content and microphones.
Turning this control clockwise will increase the overall volume of the
complete system. This will also effect the signal level which is supplied to
the line output sockets, and also the signal which is recorded by the tape
player.
The KL-1 is tted with a tape cassette player which accepts normal
magnetic compact cassettes.
We have added a +/- 5% pitch control to this standard mechanism to allow
it to be used for karaoke or aerobics applications.
The operations for this cassette are described below.
1) Press Stop/eject button (14, page 3) to open cassette door.
2) Place compact cassette into the cassette door with the magnetic strip
facing downwards. Close the door by rmly pushing it back into the
cabinet until a rm click is heard.
3) To play a cassette, ensure that music selector switch (12, page 3) is set
to tape.
4) Press play button (17, page 3) down to activate play sequence.
5) When the cassette has nished playing this side, it will auto stop. It
is necessary to open the tape door (by pressing eject), and remove the
compact cassette and turn it through 180 degrees to allow the otherside
to be played. Insert the cassette back into the cassette door, close the
door again as described above.
6) Repeat the above sequence to commence playing of this side of the
tape.
7) To advance the cassette using fast forward, rst press stop to stop the
tape playing.
8) Press FWD button (15, page 3), this will lock on and commence winding
the tape forward. To stop this action press stop button again.
9) To rewind the tape press stop.
10) Press REW button (16, page 3), this will lock on and commence
rewinding the tape backwards. To stop this action press stop button
again.
11) Both rewinding and fast forwarding will automatically stop when the
end of the tape is reached.
12) To pause the tape whilst playing, press pause button until it is locked
on. This will temporarily stop the tape in that position. To resume play
press the pause button again. Note it is not recommended to pause a

into the cassette door as described. Ensure the tape has not had its
security tabs removed which then will not allow recording. Press the
Play and Rec buttons (18, 17 page 3) down at the same time to
activate recording. It is possible to use pause control whilst in Rec
mode, this will allow eaisier stopping and starting at desired recording
positions. The level of the recording signal can be altered by the
master volume control, a certain amount of trial may be necessary to
determine the best master output for your recording purposes.
14) To stop the tape recording press stop button (14, page 3)
15) To adjust the speed of the tape, rotate the Tape pitch knob (19, page
3) anticlockwise to reduce the speed or clockwise to increase it. The
pitch adjustment on the tape mechanism is +/-5%. Return the tape
pitch knob to the 12 o’clock position to play the tape at normal speed.

The KL-1 is tted with a 3 channel light sequencer. This can be used to
enhance any social occasion, and complements the audio functions of this
product.
The light sequencer is operated independantly from the main audio sytem
and can be switched on using the light sequencer power switch (33, page
3).
To change the speed of the ashing lights, adjust the speed control knob
(35, page 3), turning anticlockwise to decrease the speed, or clockwise to
