Once you have downloaded the test tones, follow the simple procedure below to properly match your
head unit’s output to the input of the amplifier:
1.
You will need to use the same source to set gain levels that you plan on using most of the time
when listening to the system. If you plan on playing CDs, burn a CD with the test tones. If you
are going to play from a flash drive, copy the .wav files to a flash drive, etc.
2.
Make sure you have all of the tone controls and high/lowpass filters (loudness, crossover, listening
position, etc.) set flat or off. This includes anything that will affect the sound of the source unit.
3.
If you are using a handheld device such as a phone, tablet, iPod, iPad, etc.…make sure the tone
settings are set flat. If you are playing the hand-held device through the 3.5 mm headphone jack
or Bluetooth, make sure the volume on the handheld device is turned all the way up.
4.
Make sure the amplifier is powered up but you do not have any speakers connected to the
amplifier’s output. Make sure the gain controls are set to the counterclockwise or minimum
position. In addition, gain setting should be done BEFORE the KXARC wireless bass control has
been paired to the subwoofer amplifier. If the bass control is already paired, make sure the
subwoofer level is set to maximum output and the Shockwave is set to its minimum output.
5.
Play the test tone with the source unit. Use 50 Hz for subwoofer outputs and 1kHz for full range
and high pass outputs. Turn the volume up to about ¾ or 75% maximum output.
6.
Begin to turn the gain adjustment knob on the amplifier clockwise until you see the gain control
knob illuminate red. When you see this, turn the control counterclockwise a small amount until
the light on the control knob turns off. At this setting, the amplifier’s output is at <1% distortion.
7.
Repeat this process for all of the additional gain controls and amplifiers in the system.
8.
Make sure the crossover settings on the amplifier/s are set correctly so as not to damage any of
your speakers. As a good starting point we recommend an 80Hz low pass on subwoofers and an
80Hz high pass on your full range channels.
9.
Connect speakers to the amplifiers and listen to the system with music. If you need to adjust any
gain control to balance the system, only turn gains counterclockwise or down.
NEVER
turn any
of the gain controls up or clockwise after you have set the proper gain level with the test tones.
This will cause those channels to distort or “clip” prematurely and can damage the speakers.
10.
Now you are ready to enjoy the music. Remember that any boosting/changes you make on the
source unit will affect amplifier output. ie. Bass Boost, Loudness, EQ, etc.
