[. . . ] low pass frequency control when the crossover selector switch is in "low pass" mode, this control sets the upper frequency limit for audio program sent to the speakers. high pass frequency control when the crossover selector switch is in "high pass" mode, this control sets the lower frequency limit for audio program sent to the speakers. bass boost level control this control permits adjustment of the bass level up to an increase of approximately 18 dB. low level inputs this amp features gold-plated RCA input jacks for high impedance input. [. . . ] power LED this indicator is illuminated when power is applied. protection LED this indicator is illuminated when built-in protection circuitry is activated. power fuse the fuse protects the amplifier and your car's electrical system from short circuit conditions. power terminals use these connectors to deliver power, ground and remote turn-on control to the amplifier. speaker connections these terminals are 14K gold plated to guarantee high conductivity and minimum signal loss. output power @ 14. 4v DC, 1KHz RMS Power @ 4 Ohms RMS Power @ 2 Ohms Maximum Power Output frequency response input impedance low level inputs high level inputs input sensitivity low level inputs high level inputs power supply voltage matching speaker impedance stereo mode bridged mode maximum current draw dimensions (W x H x L) mm inches 40 Watts x 2 70 Watts x 2 300 Watts x 2 15 Hz-30 KHz 10K Ohms 100 Ohms 250mV 2. 5V 14. 4V DC Neg.

" If you wish to use the internal crossover to power a driver of specific frequency range, use the "LOWPASS" or "HIGHPASS" settings. input level control use this control to match the outputs of your head unit to the amplifier. Starting with your head unit set at about the 2 o'clock position, increase the amp level control until distortion begins to occur, and reduce slightly from this point. low pass frequency control when the crossover selector switch is in "low pass" mode, this control sets the upper frequency limit for audio program sent to the speakers. high pass frequency control when the crossover selector switch is in "high pass" mode, this control sets the lower frequency limit for audio program sent to the speakers. bass boost level control this control permits adjustment of the bass level up to an increase of approximately 18 dB. Wire the amplifier directly to the car battery. For the ground connection, use the shortest possible wire to a good chassis ground point. Wire the Remote connection to the auto start lead of your head unit, equalizer or power antenna. About power fuses: Pyle Marine Series amplifiers feature built-in fuse systems. These fuses protect both the amplifier and the electrical system in your vehicle from fault conditions. If you ever need to replace the fuse in your Pyle Marine Series amp, use a fuse of exactly the same type and rating. A different type or rating of fuse may result in damage or fire. troubleshooting No output. Confirm that all terminal strip connections are secure and tight. protection circuitry The built-in protection circuitry in the Marine amplifiers will disable the amplifier if it senses an input overload, a speaker short circuit, or extreme temperature conditions. When the protection circuit is activated by any of these conditions, the Protection LED will be illuminated. If this occurs, carefully inspect the system to determine the source of the problem. · If the shutdown was a result of a thermal overload condition, allow the amplifier to cool down before attempting to restart it. [. . . ] Do not mount this amplifier so that the wire connections are unprotected, or in a pinched condition, or likely to be damaged by nearby objects. Before making or breaking power connections in your system, disconnect the vehicle battery. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker terminals. If you need to replace the power fuse, do so only with a fuse identical to that supplied with the amplifier. [. . . ]
