[. . . ] 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. [. . . ] speaker connections these terminals are 14K gold plated to guarantee high conductivity and minimum signal loss. blue wave 2 ch amp PLA785 features and specifications PLA785 2 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 85 Watts x 2 125 Watts x 2 400 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. 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.

When determining a suitable location in your vehicle for the amp, please remember that it is a high-power electronic device capable of generating high heat. For this reason, always choose a location in your vehicle which has low vibration, adequate ventilation, a minimum of dust, and no moisture. Be sure to mount the amp in such a manner as to allow reasonable airflow over the cooling fins. Mark the location for the mounting screw holes by positioning the amp where you wish to install it and use a scribe (or one of the mounting screws) inserted in each of the mounting holes to mark the mounting surface. [. . . ] Briefly tap the center pin of each of the disconnected RCA plugs with your finger. Check the Balance control on the head unit (or other source) to verify that it is set to its midpoint. 32 · If the shutdown was a result of an input overload, or speaker short circuit, be sure to correct the condition before restarting. The amplifier can be restarted by turning the remote power OFF and then ON again. If you are using the Low Level RCA input, reverse the input plugs at the amplifier (i. e. , switch the L with the R). If the channels which is silent switches to the other side, the problem is either in the head unit/other source or the connecting cables. [. . . ]
