To initialize setup process, depress the momentary switch on the microphone cable. You will have
10 seconds to exit vehicle and shut door. When setup mode is initialized, the amplifier will go through the
following process for a 4-speaker full-range system.
1.
The DSP will send electrical pulses to the speakers independently to measure the time it takes for
the acoustic pulse to return to the microphone. This will set the proper time alignment for the
front speakers improving the staging of the sound in the vehicle in increments of .00002 seconds
or 20μ seconds.
2.
With pink noise playing from the audio source in the vehicle, the DSP will adjust each of the
speakers with a 10-band equalizer to smooth out any irregular frequency response bands by
cutting or boosting each frequency band. It has the capability of boosting up to 8.5 dB and cutting
up to 12 dB at 1/100 dB increments. It will do this independently for all four speakers.
3.
Next it will measure the level of the front vs. the rear for overall output. It will adjust the rear
speaker’s output level to compliment the front speaker’s output level.
4.
The higher frequencies of the rear speakers will be reduced to bring sound stage more to the
front.
5.
When you hear the happy tones, the 4-speaker setup is now complete and the setup
switch/microphone may be unplugged and stored for later use.
6.
If you hear the sad tones, count the number of beeps to correspond to error chart in owner’s
manual. Check all connections, DIP switch settings, pink-noise level from the source, and make
sure vehicle is in a quiet environment and repeat set up process.
7.
Repeat tuning process until happy tones are heard.
8.
Once the signal is optimized, you can then choose to defeat the KICKER EQ curve for a flatter
response. You can also engage the compressor circuit to eliminate distortion caused by clipping
(overdriving) the amplifier. This will prevent damaging the speakers by ensuring the output is not
clipped by limiting the overall output. You may also select a high-pass crossover at your choice of
60 Hz, 80 Hz, or 120 Hz at 24 dB/octave.
When in bi-amp mode:
The KICKER KEY200.4 can also be used to set up and optimize a bi-amp system if you are powering
the midranges and tweeters of a component speaker system separately. It will also do the same for wider
bandwidth dash speakers (such as 3 ½”, 4”, 4 x 6”, 5 ¼” ect…) if there are larger or full-range speakers in
the dash along with speakers in the doors. The KEY will automatically determine if you have a tweeter or
larger speaker and tune accordingly.
1.
The DSP will send electrical pulses to each of the four speakers independently to measure the
time it takes for the acoustic pulse to return to the microphone. This will set the proper time
alignment and improve the staging of the sound in the vehicle in increments of .00002
milliseconds or 20μ seconds.
2.
Next it will send a signal to determine if you have only tweeters or a smaller full-range speaker
connected to amp 1. If it is a dedicated tweeter, it will apply a 24 dB/octave high pass crossover
at 3200 Hz to amp 1 and a 24 dB/octave low pass filter also at 3200 Hz to amp 2.
3.
If the DSP circuit detects a speaker other than a tweeter only connected to amp 1, it will apply a
24 dB/octave high-pass crossover at 320 Hz to amp 1 and a 24 dB/octave low-pass crossover at
640 Hz to amp 2.
