INTRODUCTION
BASIC SETUP
Congratulations for purchasing the Phonic KA720 Karaoke
Mixing Amplifier, another great innovation bound to provide
you with hours of enjoyment at a time. The power provided

Karaoke mixer, pumping 360 Watts of power to each
channel.
Featuring a total of 6 microphone inputs, as well as 4 line
inputs, the KA720 features a fully functional key adjustment
and EQs for both vocals and music. Karaoke audio and
video are input via the four included sets of RCA inputs,
and send out via the two sets of RCA outputs.

The KA720 Karaoke Mixing Amplifier can be rack mounted,
and will take up 3 standard rack units to do so. Your first
step, provided you wish to mount the KA720 into a rack,
should be to do so. Four screws, firmly in place on each
corner of the unit, will do the trick.
After this, you may wish to connect your various input, and
output, devices. The four different RCA input channels
provide you with enough to room for a DVD player with
karaoke function (or simply a DVD player, for use between
karaoke sets), an actual karaoke machine, a PC computer
(for users who opted to have the VGA inputs and outputs),
or even a standard CD player (which will not feature video
output, but can be used regardless). The Microphone inputs
on the front of the KA720 are provided for the addition of,
you guessed it, microphones. If condenser microphones
are added to the KA720, be sure to activate the Phantom
power.
Plugging the RCA audio and video outputs of the KA720
allows the audio and video to be sent to a television set
or video projection device. Passive speakers can be
connected to the main audio outputs and positioned for the
best listening experience.
Use the provided AC power cord to connect the KA720 to
an appropriate power source. Be sure to check the voltage
selector is adjusted correctly before turning the unit on.
