Polarity Positive or Negative

This section is used to select either the Positive or Negative polarity.

Phase 0 to 180

This parameter sets the amount of phase within the selected output path. The phase is refer-

enced to the uppermost frequency within the band.

The Subharmonic Synthesizer module has been specifically optimized to enhance Bass audio

material for use in a variety of professional applications, including nightclub and dance DJ mix-

ing, theatre and film sound, music recording, live music performance and broadcasting.

The Subharmonic Synthesizer module’s two separate bands of subharmonic synthesis provide

the best combination of smoothness and control, and the independent low frequency boost cir-

cuit is designed to get the most out of high-performance low frequency speaker systems.

Sub-Harmonic Synth - On/Off

Turns the Subharmonic Synth module on and off.

Sub-Harmonics Synth - 0 to 100%

This parameter sets the overall level of the Subharmonic Synthesizer.

24-36Hz and 36-56Hz (Subharmonic Synthesis) Level - 0 to 100%

These controls individually let you customize the amount of the respective synthesized fre-

quencies to be added in, tuning the ultimate bass response of your system to taste. For

example, if the sound is too woofy or growly, try turning down the 36Hz-56Hz level. If your

woofers are bottoming out (making a ticking, popping sound), try turning down the 24Hz-

36Hz level. You may find that a setting produces fine results in one room, but produces too

much boominess in another. If this occurs, adjust the controls as needed, (e.g., increase one

or the other of the band levels). Experimentation will pay off with smooth, full, deeply

extended bass. Remember, you are not selecting a frequency. You are controlling the overall

level of each band.
