User manual BLAUPUNKT VELOCITY VPA 4130 PRO

[. . . ] Do not connect loudspeakers to earth, use only the referenced terminals. The amplifier is suitable for connecting a car sound system with cinch connections. For the connection to car sound systems with ISO connection, use Blaupunkt ISO cinch adapters (7 607 893 093 or 7 607 855 094). [. . . ] - 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. switch position is ON (I / II): Only after an AF source has been connected. Caution: When making the connection, always set the volume control to minimum and switch off the amplifier. 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. 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. (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.

Tänk på om du lyssnar på musik i bilen att en långvarig ljudnivå över 100 dB kan leda till bestående hörselskador och till och med dövhet. Därför är det viktigt att vid anslutning se till att den positiva anslutningen (+) på förstärkaren är kopplad till högtalarens positiva anslutning (+). [. . . ]
