User manual PYRAMID PW12290

[. . . ] 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. when the crossover selector switch is in "low pass" mode, this control sets the upper frequency limit for audio program sent to the speakers. when the crossover selector switch is in "high pass" mode, this control sets the lower frequency limit for audio program sent to the speakers. [. . . ] when the crossover selector switch is in "high pass" mode, this control sets the lower frequency limit for audio program sent to the speakers. this control permits adjustment of the bass level up to an increase of approximately 18 dB. this amp features gold-plated RCA input jacks for high impedance input. Use these with car stereo output which uses RCA-type connector cables. if your car stereo lacks RCA-type output jacks, you may connect speaker output leads to these input connectors. this indicator is illuminated when built-in protection circuitry is activated. the fuse protects the amplifier and your car's electrical system from short circuit conditions. this indicator is illuminated when built-in protection circuitry is activated. the fuse protects the amplifier and your car's electrical system from short circuit conditions. use these connectors to deliver power, ground and remote turn-on control to the amplifier. these terminals are 14K gold plated to guarantee high conductivity and minimum signal loss. input level controls 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 15 Hz-30 KHz 10K Ohms 100 Ohms 250mV 2. 5V 14. 4V DC Neg.
