Features1 - EQ BOOST / FLAT: When set in the “FLAT” position, frequency response is linear and unaltered. When“Boost” is selected, internal equalization is applied to enhance low frequency and highfrequency response. “FLAT” will provide greater accuracy of reproduced music, higherspeech intelligibility and maximum overall level. “BOOST” is particularly useful at lowerlevels to enhance pre-recorded music. The feature provides flexibility without the needto use an external equalizer. The chart (at right) shows the effect of the “BOOST” setting.MAIN/MONITOR*: Switching between “MAIN” and “MONITOR” optimizes the system for use as either a mainfull-range system, or a stage monitor.SYSTEM SET UP - FULL RANGE MODELSPOWERLINE SELECTAC LINE INPUT100V~ -240V~50/60 Hz 5A 600WMIC LEVELLINEFLATBOOSTOUTINOVERLOADSIGNALllINPUTEQDesigned, Engineered and Assembled in U.S.A.JBL PROFESSIONALNorthridge, CA.
