User manual SONY XM-3060

[. . . ] built in Low-pass-filter , High-pass-filter , Subsonic filter and Low boost circuit. Direct connection can be made with the speaker output of your car audio unit if it is not equipped with the line output (High level input connection). Hi-level Sensing Power On feature allows unit to be activated without need for REMOTE connection. * Pulsepowersupply This unit has a built-in power regulator which converts the power supplied by the 12 V DC car battery into high speed pulses using a semiconductor switch. [. . . ] Use speakers with an impedance of 2 to 8 (4 to 8 when used as a bridging amplifier). Do not connect any active speakers (with built-in amplifiers) to the speaker terminals of the unit. Avoid installing the unit in areas subject to: -- high temperatures such as from direct sunlight or hot air from the heater -- rain or moisture -- dust or dirt. If your car is parked in direct sunlight and there is a considerable rise in temperature inside the car, allow the unit to cool down before use. When installing the unit horizontally, be sure not to cover the fins with the floor carpet etc. If this unit is placed too close to the car audio unit or antenna, interference may occur. In this case, relocate the amplifier away from the car audio unit or antenna. If no power is being supplied to the car audio unit, check the connections. This power amplifier employs a protection circuit* to protect the transistors and speakers if the amplifier malfunctions. Do not attempt to test the protection circuits by covering the heat sink or connecting improper loads. Do not use the unit on a weak battery as its optimum performance depends on a good power supply. When you tighten the screw, be careful not to apply too much torque* as doing so may damage the screw. * The torque value should be less than 1 N· Note When connecting the front input, sound is output through the rear speakers. 4 ) Notes In this system, the volume of the subwoofer will be controlled by the car audio unit fader control ( or ). In this system, the output signals to the subwoofer will be the combination of both the REAR L and R INPUT jacks or the REAR high level input connector signals. In this system, the volume of the subwoofer will not be controlled by the car audio fader control (). If *1 you have the factory original or some other car audio unit without a remote output for the amplifier, connect the remote input terminal (REMOTE) to the accessory power supply. In High level input connection, car audio unit can also be activated without need for REMOTE connection. Si *1 vous disposez de l'autoradio d'origine ou d'un autre autoradio dont l'amplificateur ne comporte pas de sortie de télécommande à distance, raccordez la borne d'entrée de commande à distance (REMOTE) à la prise d'alimentation accessoires. Before making any connections, disconnect the Ground terminal of the car battery to avoid short circuits. Do not connect the terminal of the speaker system to the car chassis, and do not connect the terminal of the right speaker with that of the left speaker. Install the input and output cords away from the power supply wire as running them close together can generate some interference noise. [. . . ] May not perform to its full potential if used with the speaker cords supplied with the car. If your car is equipped with a computer system for navigation or some other purpose, do not remove the ground wire from the car battery. To avoid short circuits when making connections, disconnect the +12 V power supply wire until all the other wires have been connected. Connect the +12 V power supply wire only after all the other wires have been connected. [. . . ]
