KX100
Section 3 Processing & Parameters
3.2 Automatic Gain Control (AGC)
Automatic Gain Control is a dynamics process which compensates for the differences in level
between varying music sources, thereby allowing you to effectively raise lower level music
material for a more consistent level.
AGC Parameters
The AGC algorithm contains the following parameters:
• AGC Enable - This parameter turns the AGC algorithm on or off.
• AGC Threshold (-80 dB - -50 dB) - The Threshold sets a lower limit to the AGC. This
prevents the AGC from adding gain to low level signals or when no signal is present.
• AGC Max Gain (1 dB - 20 dB) - This adjusts the maximum amount of gain that will be
added by the AGC algorithm.
• AGC Target (-40 dB - -1 dB) - The Target parameter defines where you would like
the average level of the AGC output to be. For signals with an average level below the
Target, the gain will be increased. If the average level of the signal rises above the
Target, the gain will be reduced.
• AGC Window (1 dB - +10 dB) - This parameter adjusts how much the output level is
allowed to wander from the set Target parameter.
• AGC Attack (1 sec - 9.9 sec) - This adjusts how fast the AGC will increase gain.
• AGC Release (10 dB/sec - 0 dB/sec) - This adjusts how fast the AGC will reduce gain.
3.3 Center Mix
Center Mix allows you to route the microphone or music to the center output channel or
provide a mix of the two signals.
Center Mix Parameters
Center Mix contains the following parameter:
• Center Mix (Mic, 1-99, Music) - Rotating the Adjust/Select knob all the way to the
left (Mic) will send only the mic signal to the center output channel. Rotating the
Adjust/Select knob all the way to the right (Mus) will send only the music signal to
the center output channel. Values between 1 and 99 will blend or mix the two signal
levels. Setting this parameter to 50 will yield a 100% mix of both microphone and
music.

15
KX100 Section 3
Processing & Parameters
3.4 Dance Mode
Dance Mode is used to switch between using the PA system in a dance club environment
(Dance Mode) or for karaoke use (Sing Mode). When Dance Mode is turned on, the subwoofer
can be enhanced for dance club use. This feature makes it very easy to use the live sound
system for both purposes.
Dance Mode can either be engaged manually or automatically. The Dance Mode Timer allows
you to automatically engage Dance Mode after a period when the microphones are not used.
Dance Mode Parameters
Dance Mode contains the following parameters:
• Sub Dance Mode (Auto, Sing, Dance) - This parameter selects whether the system
is optimized for karaoke (Sing Mode), dance club use (Dance Mode), or is automatic
(Auto).
1. Auto: Turns Dance Mode on whenever the microphone signal level drops below
the Sub Dance Sensitivity parameter for a given amount of time (the time is set
by the Sub Dance Time parameter). When the microphone signal level is once
again present and exceeds the Sub Dance Sensitivity parameter, the system will
automatically switch back to Sing Mode, for karaoke use.
2. Sing: Manually turns Sing Mode on (for karaoke use)
3. Dance: Manually turns Dance Mode on (for dance club use).
• Sub Dance Time (0 ms - 2 sec) - This parameter adjusts how long it takes for Dance
Mode to switch from Sing Mode to Dance Mode after a period of inactivity at the mic
inputs. This parameter is only active when the Dance Mode parameter is set to Auto.
• Sub Dance Sensitivity (-60 dB - +3 dB) - When Sub Dance Mode is set to Auto,
this parameter sets the microphone threshold. When the mic level falls below this
‘Sensitivity’ parameter (or threshold), Sub Dance Mode will countdown the Sub Dance
Time (if set above 0 ms) then automatically switch from Sing Mode to Dance Mode.
• Sub Dance Volume (-30 dB - +6 dB) - This parameter sets the subwoofer level when
Dance Mode is engaged.
• Sub Sing Volume (-30 dB - +6 dB) - This parameter sets the subwoofer level when
Sing Mode is engaged.
3.5 Driver Alignment Delay
Driver Alignment Delay is available on the Left/Right, Center and Subwoofer outputs. It is
used to time align the signal from the various speakers so that all loudspeaker signals arrive
at the audience at approximately the same time, thereby reducing phase issues.
Delay Parameters
Delay contains the following parameter:
• Delay (0 ms - 40 ms) - This parameter sets how much delay will be applied to the
selected output.

Section 3 Processing & Parameters
3.6 Echo
The Echo effect consists of delays which generate the artifical echos. In an echo effect, the
processed signal is mixed with the unprocessed signal and is used to make a singer’s voice
sound more interesting. Echo has adjustable time, feedback and level for producing that
sought after karaoke effect.
Echo Parameters
The Echo algorithm contains the following parameters:
• Echo Type (see selections below) - This parameter selects the type of echo algorithm
used. The Echo effect contains the following selectable options:
Off When selected, this option turns the Echo effect off.
Stereo Delay
This algorithm creates a stereo delay effect where the delays are
heard at different intervals between the left and right speakers.
Mono Delay
This algorithm creates a mono delay effect where the delays occur
simultaneously between the left and right speakers.
Stereo Triplet Delay
This algorithm creates a stereo delay with up to three taps
(individual delays), which are adjustable using the Echo Tap
Position and Echo Tap Volume parameters.
Multi Tap Delay
Much like the Stereo Triplet Delay algorithm, this algorithm creates
a stereo delay, but with up to six taps (individual delays), which
are adjustable using the Echo Tap Position and Echo Tap Volume
parameters.

The Karaoke algorithm creates typical karaoke type delays.
The different selectable options will have varying delay times.
Auditioning each type will determine which best suits your taste.
• Echo Delay (0 ms - 2500 ms; range is preset dependent) - This parameter adjusts
the amount of delay which occurs before you begin to hear any repeats. This parameter
is also adjustable from the front panel Delay knob.
1. Karaoke Preset’s Range: 0 ms - 740 ms
2. All Other Preset’s Range: 0 ms - 2500 ms
• Echo Repeat (0 - 99) - This parameter adjusts how many times the delay will be
repeated. The higher the value of this parameter, the longer the delay effect will be
heard before fading out. This parameter is also adjustable from the front panel Repeat
knob.
