User manual BLAUPUNKT GTA 250 BP11 INSTALLATION

[. . . ] For devices purchased outside the European Union, the warranty terms issued by our respective responsible domestic agency are valid. Please observe the following safety notes during the installation and connection. ­ When you drill holes, ensure that you do not damage any vehicle components. ­ An incorrect installation can result in malfunctions of the electronic vehicle systems or your car sound system. [. . . ] In conclusion, allow us a few words about the topic of health protection: During the playback of music in your vehicle, please consider that continuous sound-pressure levels above 100 dB can lead to permanent damages to the human ear and even to loss of hearing. Using today's high-performance systems and loudspeaker configurations allows for reaching soundpressure levels above 130 dB. Please observe the following safety notes during the installation and connection. ­ When you drill holes, ensure that you do not damage any vehicle components. ­ The cross section of the plus and minus cable may not be less than 6 mm2. ­ An incorrect installation can result in malfunctions of the electronic vehicle systems or your car sound system. You can select between 2 different audio inputs; ­ Cinch (RCA) ­ Hi level (loudspeaker connections) Use only one of the audio inputs; otherwise, it may lead to audio interferences. The preamplifier outputs are connected to the cinch (RCA) sockets 1 via a shielded sound cable. with control via the loudspeaker outputs , the input connections of pos. 2/3 are fed to the closest loudspeaker cables (front or rear) on the left and right. Bridge output stages (BTL) can also be connected directly without an additional adapter. With respect to accident safety, the GTA 250 BP11 must be secured in a professional way. When selecting the installation location, select a dry location that offers sufficient air circulation for cooling the amplifier. The GTA 250 BP11 must not be installed on rear shelves, rear seats or other locations that are open to the front. The installation location must be suitable to accept the accompanying screws and provide a firm support. ­ Securely fasten commercially available minus cables to a noise-free earth point (chassis screw, chassis metal) (not to the minus pole of the battery). ­ Scrap the contact surfaces of the earth point until they are bright and grease with graphite grease. This allows the amplifier to be used for one or several subwoofers or mid-range drivers. In this configuration, the amplifier combines the right and left channel to a singlechannel output (mono output). Note: The amplifier can add the right and left signal information only if the right as well as the left RCA connection were carried out. Caution: In a bridge circuit, the amplifier load must be 4 ohm or higher. A lower load leads to an overheating or switch-off of the amplifier and can cause permanent damages. [. . . ] The fuses integrated in the amplifier (Fuse) protect the power amplifier and the entire electrical system in case of an error. If a replacement fuse is used, never bridge fuses or replace them with a type with higher current. This allows the amplifier to be switched on and off using the on/off-switch of the radio device. The Level control is used to adjust the input sensitivity of the power amplifier to the output voltage of your car sound system preamplifier output. [. . . ]
