All instruments and vocals have their own f requency band' as shown in the figure. inBy moving the controls up or down, the volume of the instruments struments preferred can be boosted or other can be attenuated. and For instance, it is possible to boost the 60 Hz frequency give the bass drum a greater "punch" or boost the 1 kHz ir"qr"n"y and position the vocals at the front' When the 6 kHz frequency is boosted, the cymbals and "high hat" sound much clearer. lnstruments and vocals have a great many harmonic components along with the fundamental frequency band and so you can have lots of fun operating the 7 controls to achieve the sound of Your choice. ln order to protect the speakers from damage resulting from power overload, do not excessively increase the stereo amptifier's volume level when boosting the treble range on this unit'
