An equalizer is an sound processor used to adjust the volume or gain of different frequency ranges in an sound signal to achieve a balanced and equalizing effect on the sound signal. <br>3、Adjusting Spectral Balance: An Equalizer adjusts the volume of different frequency ranges of an sound signal to make bass, midrange and treble more balanced across the frequency spectrum. By boosting or diminishing the volume of specific frequency ranges, sound clarity and timbre can be improved. <br>4、Eliminate Feedback Problems: In live sound applications, equalizers can be used to eliminate feedback problems in an sound system. By attenuating the volume of a feedback frequency range, feedback sounds can be reduced or eliminated, improving the stability and reliability of the sound system. <br>5、Adjusting Sound Effects: Equalizers can be used to adjust special effects in sound, such as increasing bass effects and emphasizing vocals. By adjusting the volume of different frequency ranges, various sound effects can be customized and adjusted.<p>1 x Equalizer<br>1 x USB Cable<br>1 x User Manual<br>1 x Sound Cable<br>1 x Knob<br>1 x Connection Cable</p>
