User manual BLAUPUNKT GTA 280

[. . . ] The Blaupunkt editors are constantly working on making the operating instructions clearer and easier to understand. However, if you still have any questions on how to operate the equipment, please contact your dealer or the telephone hotline for your country. You will find the hotline telephone numbers printed at the back of this booklet. We provide a manufacturer guarantee for our products bought within the European Union. [. . . ] 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 (see table or installation drawing). Do not connect the loudspeakers to ground; only use the terminals provided. The crosssection of the positive and negative cable must be at least 6 mm2. gTA 280 amplifier The amplifier is suitable for connection to car radios with Cinch connector. Use the Blaupunkt ISO Cinch adapter to connect the amplifier to car radios with ISO connector. Adjust the input sensitivity in accordance with the manufacturer's specifications when connecting the amplifier to other radios. important: Turning the Level control clockwise increases the input sensitivity of the amplifier , and thereby also the volume. The Level control is however not a volume control; an increase in volume is not achieved in the maximum position, even if this subjectively appears to be the case. The system merely increases the volume more quickly when the volume is turned up on the radio. 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. [. . . ] Never bridge fuses or replace fuses with a higher current rating. This enables the amplifier to be switched on and off with the radio's On/ Off switch. Level control The Level control enables the input sensitivity of the final stage to be matched to the output voltage of your car radio preamp output. Level reglering Med hjälp av Level regleringen kan slutstegets ingångskänslighet anpassas till utgångsspänningen för bilradions förförstärkarutgång. [. . . ]
