User manual BLAUPUNKT GTA 2100

[. . . ] Recommendation: A power amplifier's performance is only as good as its installation. Proper installation will maximise the overall performance of your audio system. We recommend that you have our product installed professionally. Should you decide to install the amplifier yourself, however, please read through these instructions carefully, and take your time over the installation. [. . . ] gTA 2100 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. 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 used simultaneously with stereo satellite speakers (mid-range and tweeter) and a mono subwoofer. The connections are somewhat more complicated in this case, as they require the use of passive crossover networks (not supplied with the amplifier) which divide the frequency ranges between the various loudspeakers. The requisite connections can be taken from the diagrams below. If you do not wish to purchase and connect the components separately, a number of ready-assembled tri-mode crossover networks are available. ask your local car audio retail store for details. CAUTION: In tri-mode (combined mono/stereo mode) the amplifier must be presented with a load of at least 2 Ohms (stereo satellite speakers) or 4 Ohms (mono subwoofers). 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". [. . . ] Positive/negative connection We recommend a cable cross-section of not less than 6 mm . 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 neg3 This information is subject to change without notice! [. . . ]
