KA720
19...Level.Meter
The KA720’s level meter gives an accurate indication
of when audio levels of the main signal reach certain
levels. To make the maximum use of audio, set the
various levels controls so that the uppermost LED of
the level meter flashes only occasionally, or not at
all.
20...Key.Control.and.Indicators
This area allows users to control the key of the music
currently selected (through use of the input select
buttons), and does not affect the vocal channels
whatsoever. The key can be increased or decreased
in half-key increments by pressing the appropriate
buttons (the top button being increase, the lower
button being decrease). The center key is used to
return the music back to its original state.
When a key is increase by half a step, two of the
included LEDs will illuminate to indicate the key is half
way between the two. When the key is increased by
another half step, only the single LED will illuminate
(and so on). The maximum a user can increase or
decrease the key by is steps.

21.. .Video.and.Audio.Inputs
These RCA jacks allow users to connect video and audio
inputs to the KA720. The RCA jacks are color-coded,
yellow being video, white being the left audio channel and
red being the right audio channel. Users are able to select
from these inputs by using the Input Selection buttons on
the front panel.
22.. .Video.and.Audio.Outputs
These two sets of RCA jacks are for the output of video and
audio from the KA720 to televisions or video projectors and/
or stereo systems. The Preamp output (the output of which
is not affected by the balance control on the front panel)
can be used for displaying the video and audio signals to a
small television set for monitoring purposes.

23.. .EFX.Input
These /” phone jacks are for returning the EFX signal
to the KA720, after being processed by an external signal
processor. The EFX Input signal is adjusted by the EFX In
control located on the front panel of the KA720.
24.. .EFX.Output
This jack outputs the main signal to external processors to
be returned via the EFX input.
25.. .EQ.In.and.Out
These stereo RCA inputs and outputs allow users to extract
the main audio signal from the KA720, send it off to an
external equalizer, and then return it to the device once
more.
26.. Remote.Key.Control
These /8” TRS inputs are for customized key control
pedals. Users should wire their pedal so that when the
connector’s tip and sleeve form a connection, the key will go
up by half a step and that when the ring and sleeve touch,
the key will go down by half a step. A total of two remote
key controls can be used simultaneously, both of which will
affect the main Key Control unit on the front panel.
27.. .Fan
This fan is for cooling of the KA720 karaoke mixer, and
should not be obstructed at any time. Doing so may cause
overheating in the product.
