Figure 21: EQ Select Button
The total EVO System can be optimized for an individual program using the EQ SELECT button (Figure 21). Each press of the button will apply a different EQ curve to the entire system, very much like the way a domestic HiFi or car stereo EQ is used to optimize the system for different types of music. The settings scroll through as follows:

ANTI FEEDBACK CONTROL
Two different types of Anti Feedback Control engines can be initiated and set up via EVOi.net: Live Anti Feedback
Control and Fixed Anti Feedback Control.
Live Anti Feedback Control is designed to be used during a performance. Once initiated, six dynamic filters are set into action, instructed to search for and eliminate feedback once found. When feedback is detected, a filter is placed to eliminate it before it “runs away”. If additional feedback is found, another filter is used. The FILTERS FREE indicators tell you how many of the six filters are left.
Fixed Anti Feedback Control is designed to eliminate feedback before a performance begins, a routine possibly done during a soundcheck. For a fixed stage setup of microphones, once initiated, six filters are available to eliminate feedback. The FILTERS FREE indicators also tell you how many filters have been used.
Note: There should be no feedback with a correctly set up and operated sound reinforcement system. The general idea of the FILTERS FREE indicators is as a guide to the operator. If all the Anti Feedback Filters have been used, this is a strong indication that the whole system needs adjustment. Typically this is confined to the mix.
