The lanes on the left side contain the really low frequency content, mainly bass, bass vocals, and the kick and tom drums The middle lanes make up the fundamental zone of most musical instruments and the male and female vocals The right-hand lanes have all the high-frequency stuff , such as snare drums, cymbals, higher pitched percussion instruments and the content that adds sizzle to the mix Key Features Shape your sound and eliminate feedback with 7 bands of equalization This Behringer product has been designed to compete head to head with leading products on the market Wide frequency range from 50 Hz to 10 kHz with a powerful 15 dB boost/cut per band Status LED for effect on/off and battery check Runs on 9 V battery or the Behringer PSU-SB DC power supply (not included) First-class electronic On/Off switch for noise-free operation 3-Year Warranty Program Designed and engineered in Germany
