Workingwithapartner,one inthelisteningposion and one at the REL manipulangthe controls,isthe
mosteffecveand efficient way to setup the REL. If working alone, the inial stepsintheset-upcanbevery
effecvelycarriedoutfrom the locaonoftheREL. Trying to ignoreallothermusic in the track,listen for
thebassdrum and its effecton the listening room.
Phase Orientaon: Once in the corner phase can be adjusted.Thismaybe the single mostcrical step,and
becauseitreallyisquitesimple, it isoenover-thought.Keepinmind;therightphaseiswhicheverposion
istheloudestorfullest.Whileplaying music with true low bass, adjust the crossoverto a point wherethe
RELandthe speaker aresuretoshare frequencies(abouthalfway up, or at 12 o’clock on the crossover
control,orslightlyhigherforsmaller speakers). Atthispointturn the HI/LOWLEVELcontrolupsothatboth
