User manual BLAUPUNKT GTA 2100B

[. . . ] Whether you are upgrading an existing system or using the GTA power amplifier in a new system, you are certain to notice immediate performance benefits!We provide a manufacturer guarantee for our products bought within the European Union. You can view the guarantee conditions at www. [. . . ] 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 2100B 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. 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. [. . . ] This can lead to permanent damage of the unit. 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.
