[. . . ] 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. [. . . ] Use these with car stereo output which uses RCA-type connector cables. high level inputs if your car stereo lacks RCA-type output jacks, you may connect speaker output leads to these input connectors. 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. 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. low level inputs this amp features gold-plated RCA input jacks for high impedance input. Use these with car stereo output which uses RCA-type connector cables. high level inputs if your car stereo lacks RCA-type output jacks, you may connect speaker output leads to these input connectors. 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. blue wave 5 ch amp PLA1585 features and specifications PLA1585 5 channel amplifier 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 70 Watts x 4 + 100 Watts x 1 100 Watts x 4 + 150 Watts x 1 250 Watts x 4 + 400 Watts x 1 15 Hz-30 KHz 10K Ohms 100 Ohms 250mV 2. 5V 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 13 14. 4V DC Neg.

[. . . ] If the noise is a "whine" whose pitch follows the engine speed, confirm that the amplifier and any other signal sources (head unit, etc. ) are properly grounded. If the noise is a "clicking" or "popping" noise whose rate follows the engine speed, this usually means that the vehicle is equipped with resistor spark plugs and wires, or that the ignition is in need of service. Check the rounting of the speaker and input wires to make sure they are not adjacent to wires which interconnect lights and other accessories. If the above steps fail to improve or clear noise interference, the system should be checked by a professional mobile audio installer. precautions Do not operate the amplifier when it is unmounted.
