Filter circuit Preamp Remote Lowpass output level w crossover control crossover eprint recepticle Locate the rotary dial marked LPF This is the LowPass Filter crossover for the amplifier The lowpass crossover points are fully variable from 50Hz to 250Hz making them ideal for subwoofers Adjust this dial either to the recommended crossover frequency for the subwoofer or more importantly to a level where the subwoofer blends well with the midrange Note Due to the limited frequency range of these Class D amplifiers the crossover is always active SUBSONIC FILTER The subsonic filter is used to reduce the amount of low mony harmonics and or subsonic noise picked up in audio systems Both of these can be damaging to subwoofer and possibly the amplifier As well harmonics and subsonic noise can cause the amplifier to pull excess power from your electrical system The subsonic filter on the BMF600D 1000D is selectable ON OFF and variable from 20Hz to 50Hz We make this switchable ON OFF for every system is different For most people it is desirable to have the filter on However if you have an outright SPL system it may be beneficial to remove the subsonic filter because harmonics can actually increase the sound pressure in many cases So what frequency should you set the subsonic at For most applications it is desirable to leave this between 20Hz and 30Hz If you are using a ported enclosure designed for SPL yet you are using the
