Number Fixed - 0-12

This will range from values 0-12. The total number of filters will stay at 12, and the number

of live filters will be = Total Num Filters – Num Fixed. If this is changed before the filters

are reset, then the filters will be reset one by one as the number changes. For example, if

the number of Fixed filters goes down, then the last fixed filter set will be reset. Likewise, if

the number of Fixed filters goes up (and thus the number of live filters goes down), then the

last live filter set will be reset. The Fixed/Live filter usage will be indicated at the bottom

of each page of the feedback elimination effect. ‘F’ indicates an available fixed filter, and ‘L’

indicates an available live filter. A blocked out F or L indicates a filter that is set, or in use.

Live Filter Lift (On/Off)

This parameter turns the Live Filter Lift on and off.

Lift After - 5 sec to 60 min

This parameter allows the user to setup the AFS module so that the Live filters will

automatically be removed or set to flat after a set time (as indicated by the “Lift After”

parameter). It ranges from 5 seconds to 60 minutes. This feature is useful if the microphone

being used is moved or the characteristics of the venue change over time. As example; a

filter placed minutes ago will not be presently preventing feedback. This feature removes

unnecessary filters from the spectrum to increase sonic quality. If the feedback is still there

(after the filter is removed), it will catch it and notch it out the same.

5.3 Subharmonic Synthesizer

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

mixing, 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

circuit 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

frequencies 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

or decrease 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.

IMPORTANT! The Subharmonic Synthesis process creates very low frequency audio material

that some speakers may not be designed to reproduce. Attempting to achieve enhanced
