[. . . ] We provide a manufacturer guarantee for our products bought within the European Union. You can view the guarantee conditions at www. De or ask for them directly at: Blaupunkt GmbH, Hotline CM/PSS 6, Robert Bosch Str. 200, D-31139 Hildesheim, Germany Recommendation: A power amplifier's performance is only as good as its installation. [. . . ] 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 GTA 4100B 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. 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. Integral fuses The integral fuses within the amplifier protect the final stage and the entire electrical system in the event of a fault. 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. Gain control The gain control enables the input sensitivity of the final stage to be matched to the output voltage of your car radio preamp output. Adjust the input sensitivity in accordance with the manufacturer's specifications when connecting the amplifier to other radios. important: Turning the gain control clockwise increases the input sensitivity of the amplifier , and thereby also the volume. The gain 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. Tri-mode loudspeaker connections GTA amplifiers can be used in a combined mono/stereo mode (Fig. This facility enables the amplifier to be uq°d simultaneously with stereo satellite speakers (mid-range and tweeter) and a mono subwoofer. [. . . ] Note: If the amplifier is to be used in the tri-mode configuration, the crossover frequency selector switch must be set to "Flat" in order to make the full frequency range available.
