User manual BLAUPUNKT TP E2 W/R PL

[. . . ] Finally, a word about your health: please bear in mind when playing music in your car that sustained sound levels above 100 dB can damage your hearing and may even result in total hearing loss. Modern highperformance systems and high-quality loudspeaker configurations are quite capable of generating noise levels above 130 dB. Safety precautions Instructions for installation and connection Fit a fuse in the amplifier power line no more than 30 cm from the vehicle battery, in order to protect the battery in the event of a short-circuit between it and the power amplifier. The amplifier's own fuse protects the amplifier itself, but not the car battery. [. . . ] Observe the vehicle manufacturer's safety instructions (regarding airbags, alarm systems, trip computers, vehicle immobilisers). The final stage must be installed professionally for reasons of safety. The mounting surface must be suitable for the screws provided, and must provide firm support. When drilling holes, take care to avoid damage to vehicle components (battery, cables, fuse boxes). The mounting location must also be dry, and provide sufficient ventilation for cooling of the amplifier. Use cable grommets when passing cables through holes with sharp edges. Use loudspeakers with an impedance of 2 to 4 . Do not connect the loudspeakers to ground; only use the terminals provided. The cross-section of the positive and negative cable must be at least 6 mm2 . amplifier TP E2 W/R PL The amplifier is suitable for connection to car radios with Cinch connector. Lower loads cause overheating of the amplifier and may damage it permanently. loudspeaker connections (If the amplifier is to be connected in a bridged mode , proceed with the section "Bridged loudspeaker connections". ) As with any audio component, connection of the amplifier and speakers with the correct polarity is essential for good bass reproduction. This enables you to use the amplifier for one or more subwoofer(s) or a mid-range speaker. In this configuration the amplifier sums the right-hand and left-hand channels, delivering a single channel (mono) output. Note: The amplifier can sum the right- and left-hand signal information only if both the right- and left-hand RCA connections have been made. CAUTION: The amplifier must be presented with a load of 4 Ohms or higher in bridged mode. a lower load will cause the amplifier to overheat or switch off. This can lead to permanent damage of the unit. Positive/negative connection We recommend a cable cross-section of not less than 6 mm2. [. . . ] run a standard commercial positive cable to the battery and connect to the fuse holder. Use cable grommets when passing cables through holes with sharp edges. Bolt a standard commercial negative cable to a ground point free of induced noise (car body bolt, body panel) - not to the negative battery pole. Clean the contact surface of the ground point down to bare metal and coat with antiseize graphite petroleum. [. . . ]
