3. THE CROSSOVER S Determine your system plans and set the crossover mode switch accordingly If your system design does not include a subwoofer set the crossover mode to FULL and skip to Setting Input Sensitivity If your system includes a subwoofer set the crossover mode to HP high pass for your full range speakers Adjust the crossover frequency to limit bass and provide increased system volume with less distortion MODE SWITCH Full Allows a full range signal through to the speakers can be used with larger full range speakers such as 6 x 9 s HP Allows a high pass signal through to the speakers should be used with most loud speakers can protect your full range speakers from being overdriven with low frequencies one cause of speaker damage LP Allows only bass to pass through to the speakers should be selected when powering subwoofers High Pass Filters Initially set the crossover frequency control midway While listening to music adjust the crossover for the least perceived distortion from the speakers allowing them to reproduce as much bass as possible Low Pass Filters For subwoofers choose the high est frequency that removes vocal information from the sound of the subwoofer If using the 475a to drive a subwoofer s set the crossover mode to LP low pass on the channels connected to the subwoofer NOTE The 1300a 1600a and the subwoofer output of the 5350a are low pass only and do not
