User manual BLAUPUNKT EMA 260

[. . . ] 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. Use cable glands for holes with sharp edges. [. . . ] 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. For example, if a pair of subwoofers is to be connected, the low-pass settings shown are required (Fig. 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. If a car sound system of a third party manufacturer is connected, the input sensitivity must be adjusted corresponding to the manufacturer data. A few important explanations in this context: By turning the control clockwise, the input sensitivity of the amplifier and, therefore, also the volume increases. However, this is not a volume control; no further amplifier output can be achieved in the end position, even if it may sound like that at the beginning. The system merely increases the volume faster if the volume control of the car sound system is turned up. Green LED: Output stage on, regular operating status. Red LED: Output stage is electronically switched off due to an error. Use cable glands for holes with sharp edges. ­ An incorrect installation can result in malfunctions of the electronic vehicle systems or your car sound system. With respect to accident safety, the EMA 260 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 EMA 260 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. The amplifier power cable must be fitted with a fuse no more than 30 cm from the battery to protect the vehicle battery in case of a short circuit between power amplifier and battery. The fuse of the amplifier protects only the amplifier, not the vehicle battery. Use loudspeakers with 2 - 4 impedance (see table or installation drawing). observe the maximum power handling capacity (music output). Do not connect loudspeakers to earth, use only the referenced terminals. [. . . ] (If the amplifier is to be jumpered, continue with the section "Bridged loudspeaker connections" at this point). As with every audio component, the correct polarisation of amplifier and loudspeakers is of essentially importance for a good bass response. For this reason, ensure that the positive (+) connection of the amplifier is connected with the positive connection (+) of the loudspeaker; the same applies to the negative (-) connections. In addition, the left amplifier channel must be connected with the left loudspeaker and the right amplifier channel with the right loudspeaker. [. . . ]
