26 Low -pass The Low-P ass filter determines the ultimate high frequency that your sound reinforcement system is allowed to reproduce; given the capabilities of amplifiers, speakers and transducers. The low-pass filter is useful for reducing excessive high frequency energy that can create stress on high frequency transducers and listener fatigue. A[...]

27 Owners Manual Hi-pass The Hi-P ass filter determines the ultimate low frequency that your sound reinforcement system is allowed to reproduce; given the capabilities of amplifiers, speakers and transducers. K eep in mind that the DC-One signal path already includes a hi-pass filter prior to the Input PEQ DSP block. Settings to this filter in most[...]

28 Input Delay DC -One offers an input delay that is useful for compensating for different arriv al times of sound originating from loudspeakers that are closer or further awa y from the listener than others.
