OVERVIEW

The KKA300 is a sophisticated and powerful microphone
mixer, voice processor, effects processor and amplifier in
a single integrated unit. It is a superb solution for either
the home Karaoke enthusiast or the professional Karaoke
performer.

FRONT PANEL CONTROLS

[1] Power switch - use this to turn the mains power on/off.
NOTE Always turn off the mains power and set all
volume controls to zero before making and audio
connections.

[2] Input Selection buttons - use these to choose the music

source you wish to sing along to. There are four separate
line level audio inputs on the KKA300 (see Rear Panel
Connections for details) available. They are labeled; DVD,
VCD, LD & AUX but you can connect any line level audio
equipment.

[3] Input Selection Indicators - each Input Selection Button
is accompanied by an LED that lights to show you which
music source is selected at a glance.

[4] Music Volume control - use this control to adjust the
playback volume of the currently selected music source.
NOTE this control does not adjust the volume of the
microphones or effects.

[5] Music Lock screw - turn this fully clockwise to 'lock' the
Overall Music Volume at its current setting. This can be
used to prevent accidental adjustment of the music
volume setting during performance.

[6] Speaker System Selection buttons - use these
buttons to switch speaker systems A and B on/off.

[7] Mute button - use this to temporarily stop all sound
being sent to the outputs.

[8] Loudness button - use this to increase/decrease the
proportion of low frequencies within your music.
Increased low frequencies tend to make music 'seem'
to sound louder.

[9] Music Tone controls - use these bass and treble
controls to adjust the tone of your music.

[10] Front Panel Microphone Inputs - use these 1/4” Jack

type microphone input connectors to connect
microphones to Mic channels 1 to 3. Mic inputs 4 & 5 are
found on the rear panel. NOTE The KKA300 features an
automated microphone feedback elimination feature.

[11] Overall Microphone Volume control - use this to set
the level of ALL 5 microphones in relation to your source
music.

[12] Microphone Volume Lock screw - turn this fully
clockwise to 'lock' the Overall Microhpne Volume at its
current setting. This can be used to prevent accidental
adjustment of the various microphone volume settings
during performance.

[13] Individual Microphone Volume controls - use these
to set the volume of each microphone in relation to the
other microphones. The first control adjust the volume of
Mic 1, the next control sets the volume of both Mics 2 & 4
and the third control adjusts the volume of Mics 3 & 5.

[14] Microphone Tone controls - use these bass, mid and
treble tone controls to adjust the tone of all 5 microphone
channels at once.

[15] Microphone Echo button - use this to switch the built
in microphone Echo Effect on/off. NOTE echo is applied
to all mic inputs unless the DJ Mic button [16] is engaged.

[16] DJ Microhpne button - this button reliminates the
Echo Effect from Mic channel 1. It is often desirable to
have the microphone used by a DJ/Compere to be free
from echo so that their voice remains clear at all times.

[17] Echo Volume control - use this to adjust the volume
of the Echo Effect in relation to the volume of your music
source and the volume of your microphones.

[18] Echo Delay control - use this to adjust the interval
between each echo of the Echo Effect. This can be used
to adjust the echo effect in such a way that the timing of
the echoes match the Beats Per Minute of the source
music and blend seamlessly with the music. Turning
clockwise increases the interval between each echo.

[19] Echo Repeat control - use this to adjust how long the
echoes of the Echo Effect continue for. Different settings
are useful for different types of music. Turning clockwise
increases how long the echoes continue for.

[20] Music Key Control buttons - use these buttons to
transpose the tone of the source music without altering it's
tempo. Each button raises or lowers the music tone by a
'semi-tone'. Using these buttons you can adjust the 'key'
of your source music to one that better suits the singers
voice or vocal range.

tempo. Press the plus button to increase by one semi-tone
or use the minus button to decrease by one semi-tone.

REAR PANEL CONNECTIONS

[27] Line Inputs (DVD, VCD, LD, AUX) - unbalanced, line
level inputs using RCA Phono connectors. These can
accept a signal from any line level audio device.

[28] Mic Inputs 4 & 5 - use these two 'combi' sockets to
connect microphones to Mic channels 4 & 5.
They will accept either 1/4” Jack or XLR type connectors
and work with any mic level signal. NOTE The KKA300
features an automated microphone feedback
elimination feature.

[29] Mic Input Earth Switches - These switches
temporarily disconnect 'earth' or 'ground' connection for
Mic Inputs 4 & 5. In complex audio set ups it is possible to
experience unwanted earth hum problems caused by
too many earth connections within the system…
using these switches to eliminate the KKA300 Mic input
earth may help to solve the issue.

[30] Record Out - connect this unbalanced line level
output to the input of a Recording device (MD etc)
to record the combined microphone and music signals.

[31] EQ In/Out - use these unbalanced line level
connections to send the combined microphone and
music signals to an external processor like a graphic EQ.
Connect the Out from the KKA300 to the In of your
processor, then connect the Out from your processor to
the In of the KKA300.

[32] Speaker Outputs - use set A and set B of these
Speakon type speaker outputs to connect the KKA300
to your speakers.

[33] Mains Power - use the IEC type mains inlet to
supply mains power to the unit. Use the Power switch
to turn the unit on/off.

[34] Power earth lift - use this to temporarily disconnect
the earth from the power supply to the unit. In complex
audio set ups it is possible to experience unwanted earth
hum problems caused by too many earth connections
within the system… using this switch to eliminate the mains
input earth may help to solve the issue.
