User manual BLAUPUNKT VR 504 VELOCITY AMP

[. . . ] velocity ReferenceAmplifier VR 504 The amplifier is suitable for connecting to car radios with cinch connector. Use the Blaupunkt ISO-Cinch Adapter for connecting to car radios with ISO connector. The development work invested in the new Velocity Amplifier offers you complete music enjoyment in your car. [. . . ] When connecting a car radio from other manufacturers the input sensitivity should be adapted in accordance with the specifications of the You can also obtain further information on our Velocity Series at our Internet address http://www. The safety instructions of the car manufacturer (airbag, alarm systems, on-board computers, engine immobilizers) must be observed. With regard to accident prevention the Velocity power amplifier must be affixed in a professional manner. The mounting surface must be suitable for accepting the enclosed screws and must offer secure installation. When drilling holes please ensure that no car components are damaged (battery, cables, fuse box). A dry position should be selected for the installation location that guarantees sufficient air circulation for the cooling of the amplifier. Preamp-INPUT Please use high-quality Velocity cinch/RCA cables for connecting the pre-amp input for right and left channels. preamp-OUTPUT Output for hook-up of an additional amp (for cascaded amplifiers). To make this connection, please use high-quality Velocity Cinch/RCA cables as well. The use of the integrated frequency divider is sensible particularly with multipath sound systems with separate subwoofer. To operate a subwoofer optimally and therefore to achieve the best sound it is necessary to decouple the frequencies in such a way that only the bass frequencies are fed to the subwoofer. In order to do this please select LP and regulate the upper frequencies between 40 Hz and 120 Hz using the crossover frequency control switch. By selecting HP the lower threshold frequency can be varied between 40 Hz and 250 Hz using the relevant crossover frequency controller. to achieve exact acoustic agreement of the frequency divider we recommend that you consult a Velocity dealer. The specifications of the loudspeakers used must be taken into account without fail when carrying out the fine adjustment of the frequency divider. Crossover frequency controller (LP + HP) If the frequency divider (low-pass or high-pass) has been activated using the crossover switch, then it is possible to adjust the crossover frequency of the relative filter between 40 Hz and 250 Hz / 40 Hz and 120 Hz in infinitely variable stages. [. . . ] Note: When set to 2-channel mode, the input sensitivity of the left channel is adjusted using the control assigned to the front inputs (CH1 and CH2) and the sensitivity of the right channel is adjusted using the control as4 Only the rear channel (CH3 and CH4) frequency filters can be activated in this configuration. Integrated fuses (FUSE) The fuses integrated into the amplifier protect the power amp and the complete electrical system in the event of faults or failures. When inserting a spare fuse, never replace with fuse types with a higher current or bridge fuses. [. . . ]
