Setting Up Your Subwoofer.

The Kompressor is a "true subwoofer, it must never be operated above the subharmonic / harmonic frequency range. The Kompressor frequency response is limited by the built-in crossover (with an upper end of 160 Hz); however, in most applications, the crossover should not be set above 80Hz to 95Hz. It is equipped with a fourth-order Linkwitz-Riley filter which will block vocals from interfering with its performance.

When setting up the Kompressor as a part of a home audio system, users must understand that the subwoofer requires different settings: one for music, and one for playing movie tracks. In order to set up the Kompressor for music, users must recognize the frequency response of their existing speakers (tower & surround sound) and the limitations of these speakers, i.e. the diameter (size) of the speakers and the SPL.

processor to "MUSIC" mode, and equalize the rest of your audio system.

4- Connect the Kompressor to the processor, using high quality (triple shielded) RCA cables.

5- Set the crossover to 150Hz - maximum position, volume at minimum (0).

6- Gradually raise the main volume knob ( between the 10 O'clock to 2 O'clock) position, optimizing for the subwoofer performance. That is when the Optical Compression Circuitry works best, allowing the amp maximum output with minimal distortion.

7- With the crossover open to 160Hz, you will hear vocals coming out of the subwoofer. Gradually reduce the crossover point until vocals are eliminated (typical crossing point of 80Hz).

To control the volume level of the Kompressor, use the surround sound processor output controls; do not use the main volume knob on the Kompressor (keep it between 10 & 2 O'Clock position). Once you set up the proper mix of low frequencies and subharmonic response, that does not encroach on the rest of the speakers. Now you are ready to set up the Kompressor for home theater use.

For movie viewing:

The Kompressor can be set up to your liking. There are no rules of thumb to how much bass is required. Often, users like to feel the overwhelming bass, it brings the actions and events closer to real life. When viewing movies, a 10dB gain above music setting is often pleasant, it brings movie viewing close to life.

If you desire to have a crossover setting for music, different than the setting for movie viewing. We suggest to cross the Kompressor at higher frequency setting, and use the processor to control the desired lower crossing point.
