In 1, the first of the equalizer limiter, feedback suppressor in bypass, through state.

In 2, according to speaker characteristics determine the electronic frequency divider frequency points, temporarily the gain 0DB set. Used as tuning equalizer.

The 3 divider used in debugging can do two or three sections of the coarse, used as tuning equalizer.

4 will test the microphone at the actors on the stage singing position, debugging feedback speaker corresponds to the equalizer, the spectral lines of flat, and according to the actual need to be appropriate to reduce the number of low frequency and Gao Po

5 according to the" industry standard" debugging respectively each speaker are Jun, the spectrum curve conforms to the" industry standard" requirement.
