HI PASS FILTER (LOW-CUT FREQUENCY CONTROL) (EQ351 and EQ355 only) To cut down on unwanted low frequency signals, this control determines the roll-off frequency of the Hi-Pass Filter (HPF). The roll-off frequency can be adjusted from 10Hz to 250Hz by turning this knob. Because of its high roll-off slope, the HPF can be efficiently used to cut down hum and low frequency noise from preceding instruments, or to reduce low frequency resonances, when speakers are installed in an enclosed acoustic environment. -
