User manual SONY XM-C1000

[. . . ] Make sure to place the unit in a well ventilated location. The power connecting wires are installed too close to the RCA pin cords. The ground wire is not securely connected. Keep the wires away from the car chassis. [. . . ] * 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. These pulses are stepped up by the built-in pulse transformer and separated into both positive and negative power supplies before being converted into direct current again. This is to regulate fluctuating voltage from the car battery. This light weight power supply system provides a highly efficient power supply with a low impedance output. This unit is designed for negative ground 12 V DC operation only. 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. Doing so may damage the active speakers. 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. Turn on or off the LPF and HPF switch at the unit rear as illustrated below. Pass the wires through the cap, connect the wires, then cover the terminals with the cap. Mount the unit either inside the trunk or under a seat. Choose the mounting location carefully so the unit will not interfere with the normal movements of the driver and it will not be exposed to direct sunlight or hot air from the heater. Do not install the unit under the floor carpet, where the heat dissipation from the unit will be considerably impaired. First, place the unit where you plan to install it, and mark the positions of the 4 screw holes on the mounting board (not supplied). Then drill a 3 mm (1/8 in) pilot hole at each mark and mount the unit onto the board with the supplied mounting screws. The mounting screws are all 15 mm (19/32 in) long, so make sure that the mounting board is thicker than 15 mm (19/32 in). 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· Car audio unit Autoradio Sistema de audio para automóvil less than 450 mm (18 in) moins de 450 mm (18 po) menos de 450 mm Notes In this system, the volume of the subwoofer will be controlled by the car audio unit fader control. 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. [. . . ] 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. If you disconnect the wire, the computer memory may be erased. 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. [. . . ]
