[. . . ] Also, save these instructions for future reference. Important: Installation of automotive stereo components can require extensive experience in performing a variety of electrical and mechanical procedures. Although these instructions explain how to install a JBL Power Series amplifier in a general sense, they do not show the exact installation methods for your particular vehicle. If you do not have the experience, do not attempt the installation yourself; instead ask your Authorized JBL Car-Audio Dealer about professional installation options. 2 P-7520 P-7540 4 SPEAKER OUTPUTS BRIDGE 5 MADE IN THE U.

[. . . ] Input Sensitivity Control ­ Adjusts input sensitivity for pre-amp level and speaker-level inputs. Pre-amp Output Selector Switch ­ Selects input path for pre-amp output. Output can be summed from front and rear inputs with no filter, or filtered by the front or rear crossover. Rear-Channel Input Selector ­ Selects rear-channel input between front input and rear input. 11. Crossover Selector ­ Determines whether the crossover is a High-Pass filter (HP), Low-Pass filter (LP) or unfiltered (flat). Crossover Frequency Control ­ Determines the crossover frequency for the amplifier channels (front or rear) and the pre-amp outputs. 3 P-2510 4 5 MADE IN THE U. S.

For power, remote and speaker wires, strip 1/4" off one end of each jacket to reveal bare wire for insertion into the barrier strip connectors. Locate the 3-connection barrier strip labeled +Batt, Rem and Gnd. Connect a black wire (at least 10G) to the Gnd terminal and connect the other end to the nearest bare-metal chassis component. (Note: Front and rear channels of the CD and radio must be driven into the front and rear inputs of the amplifier. Use Y adapters if necessary. ) The Universal Interface circuitry will isolate the two signals from each other while allowing them to drive the amp simultaneously. Therefore, switching from one source to the other is as simple as turning the unused source off and the other on. (Note: You must connect the remote turn-on wire from the CD player to the Rem terminal on the amp. Install a diode in the remote line from the CD player as shown in the diagram on this page. ) quency is variable from 32Hz ­ 320Hz. Pre-amp Outputs Connect these to the input connectors of other amplifiers or processors in your system. The crossover-selector switch determines which filter will be assigned to the preamp outputs. The pre-amp outputs may be High Pass (switch set to HP), Low Pass (switch set to LP) or unfiltered (switch set to Flat). The crossover-frequency is determined by the crossover frequency control and will be the same frequency as the amplifier channels affected by that control. Refer to the "Applications" section for system expansion possibilities. Setting Input Sensitivity Proper input-sensitivity control settings on Power Series amplifiers are critical to ensure optimum performance, low noise levels and maximum system reliability.

In this expanded system, a JBL P-7540 drives two pairs of 5-1/4" 2-way speakers. After adjusting the level of the main speakers in your system, you should adjust the remaining channels (if you are using a P-7540 or a multi-amp system) for the desired system balance. You'll find this easiest to do by adjusting the channels in the following order: 1) front speakers, 2) rear speakers, 3) subwoofer. [. . . ]
