Tuning the system
Music is the best way to begin to fine-tune your setup. We suggest
that video sources be used only after you have setup the system to
properly reproduce music.
We suggest that you start with a single vocal with instrumental
accompaniment because the sound of the human voice is more
easily recognizable than many instruments and is the least
complex sound to deal with.
Begin with the bass level
Leave the low pass filter alone, for the moment, as it should remain
set at approximately 95 Hz, This control will be addressed later.
Turn the volume control of the woofer amplifier up or down until the
voice sounds correct. Whatever controls you use, turn them up and
down only a little at a time. It is easy to turn it up or down too much.
Concentrate on the mid bass regions (as opposed to the very low
bass in your recording) to achieve a natural blend. The voice and
the music accompaniment should sound as if it were cut from one
cloth, not separate.
If the voice sounds “thin” or does not have enough “chest” to its
sound, turn the woofers amplifier’s volume up till it does. If you find
that turning the volume up creates too much low bass, you may
want to experiment with increasing or decreasing the low pass filter
control.
This control will raise or lower the frequency cutoff point of the
woofer. Turning the low pass filter up to a higher number will
extend the upper bass regions without affecting the low bass level.
Some rooms may require that you set the low-pass filter to 100Hz.
Do not be afraid to increase this control to give the sound more
body.
Next, set the woofers using more than just a voice. Select some
music that you know to have good deep bass. Using the volume
control on the servo amplifier’s remote control, set the woofers for a
natural and powerful bass sound. Use a symphonic piece of music
if you can, or use a natural bass instrument for your guide. Try to
make it sound real. You may have to return to the vocal to make
sure you have not gone too far in one direction.
