28. t advantages The most obvious is the FBX functions automatically even during the program Another is the FBX micro filters are precisely placed while EQ filters are fixed FBX filters can be placed between predetermined graphic filters The difference FBX filters do not have to be as deep so there is more system gain The final and most important advan tage is that FBX micro filters are ten times narrower than 31 band EQ filters FBX micro filters return up to 90 percent of the power removed by EQ filters Over the years engineers stopped using 12 band EQs in favor of the narrower filter 31 band EQ for controlling feedback The FBX represents the next step An EQ would need more than 10 000 sliders to be equivalent to your FBX With the SOLO your monitors will finally sound loud enough everyone in the audience will understand each word and the mains will sound natural and transparent WHO NEEDS THE FBX Virtually every sound system will be improved with the FBX Small bands that do not have sound technicians can now increase their monitor volumes so they can hear themselves clearly and with full fidelity without worrying ifthe program is going to be ruined by feedback Auditoriums and churches of all sizes will enjoy reliable feedback control Hotels and conference centers around the world can offer meeting rooms with sound systems that won t howl during pro grams The SOLO can be installed in theaters schools sports arenas co
