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. Fine-tune your system only after at least 200 hours of play. As the loudspeaker system breaks in, it will sound better and better. Using the IsoTek Full System Enhancment CD will shortcut the 200 hours needed.

Begin with the bass level

Start with a single vocal with simple 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.

Leave the low pass filter alone, for the moment, as it should remain set at 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, decrease the low pass filter control.

The low-pass 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
