16Features1 - 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 high frequencyresponse. “FLAT” will provide greater accuracy of reproduced music, higher speech intelligibility andmaximum overall level. “BOOST” is particularly useful at lower levels to enhance pre- recordedmusic. The feature provides flexibility without the need to use an external equalizer. The chart(at right) shows the effect of the “BOOST” setting.MAIN/MONITOR (PRX512M ONLY): On the PRX512M: Switching between “MAIN” and “MONITOR” optimizesthe system for use as either a main full-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.
