You can set the subsonic filter on your 1723 Series Subwoofers in the Crossover Menu and for the 1961 Subwoofers in the Setup Menu. Harrison Lab FMOD-900073 (20 Hz high-pass filter)Gold-Plated20 Hz High-Pass Filter-3 dB point 20 Hz25 Hz : 25 frequency increase at 10K ohms17 HZ : 15 frequency decrease at 47K ohmsThis high-pass filter is supposed to cut frequencies below 20 Hz, as we know the human ear can hear from 20 Hz to 20,000 Hz, so frequencies below the 20 Hz point can't be heard, and usually most speakers will. It is recommended to set up a very subsonic filter with a very steep slope (attention factor) to combat this issue. Second, the Filter/Buffer provides two buffered auxiliary inputs to enable non-GK equipped guitars or any audio source to. These warps can produce frequencies well below 20Hz and can introduce distortion into your playback system. The Filter/Buffer does three things: first, the six subsonic filters remove non-musical and mechanical noise from the output of a 13-pin Roland guitar synth controller to improve synthesizer tracking and COSM modeling. Subsonic Filters are particularly important if you spin vinyl records as they can have possible warping that causes a phenomenon known as woofer pumping. Think of the filter as a slope, not an on-off switch. It’s the opposite of a low-pass filter, which only attenuates signals above a certain line.įor example, If your subsonic filter is set to 40 Hz, 30 Hz notes will still get through but will be much quieter. In other words, it’s what we know as a high-pass filter: a filter that lets through signals above a certain Hz threshold and attenuates any signal below that threshold. It decreases the amplitude of those low notes that you feel more than you hear. A subsonic filter is a component on your subwoofer that reduces the intensity of notes which come through at lower frequencies.
