Advanced Bass Control Off On Infrasonic Freq Hz Remote Bass Port 1 Infrasonic Filter The infrasonic filter is a 24 dB octave high pass filter with a fully variable cutoff frequency between 15 60 Hz When set at frequencies lower than 30 Hz it conserves amplifier power without audibly affecting the quality of the sub bass output If set at frequencies higher that 30 Hz there will be an audible effect but one which may be desirable for SPL competition purposes or curve shaping of a bottom heavy system With ported enclosures the use of the infrasonic filter is highly recommended to protect the speaker s from excessive excursion below box tuning With sealed enclosures the use of the filter is less necessary but can still help protect the speaker system If you would like to select the infrasonic filter frequency with a higher level of precision consult Appendix A Chart A 3 page 13 of this manual The infrasonic filter can be completely defeated by selecting the Off position on the Mode switch This bypasses all signal from flowing through the circuit 2 Parametric Bass Equalizer The parametric equalizer allows the used to select the center frequency of the boost band as well as the bandwidth of the boost band The Q control selects the bandwidth of the boost around the center frequency Lower numbers pertain to wider bandwidths while higher number pertain to narrower bandwidths The C

6. JL AUDIO 1000 1 PRODUCT DESCRIPTION The JL Audio 1000 1 is a monoblock subwoofer amplifier utilizing proprietary and patented Class D technology Its frequency response is limited to the range below 250 Hz It is not designed for driving midrange speakers or tweeters Every aspect of its operation has been optimized for low frequency amplification For detailed specifications please refer to Appendix E page 21 TYPICAL INSTALLATION SEQUENCE The following represents the sequence for a typical amplifier installation using an aftermarket source unit Additional steps and different procedures may be required in some applications If you have any questions please contact your authorized JL Audio dealer for assistance 1 Disconnect the negative battery post connection and secure the disconnected cable to prevent accidental re connection during installation This step is not optional 2 Run power wire minimum 4 AWG from the battery location to the amplifier mounting location taking care to route it in such a way that it will not be damaged and will not interfere with vehicle operation Use 2 AWG or 1 0 AWG power wire if additional amplifiers are being installed with the 1000 1 3 Connect power wire to the positive battery post Fuse the wire with an appropriate fuse block and connectors within 18 inches 45 cm wire length of the positive battery post This fuse is essential to protect the vehicle Do not install the f
