User manual BLAUPUNKT V SIX VELOCITY AMP

[. . . ] Congratulations on purchasing this high-quality Car Audio Amplifier. The development work invested in the new Velocity Amplifier offers you complete music enjoyment in your car. Our Velocity Amplifiers are fitted with all typical product features expected from a high-end amplifier, but also contain a number of technical highlights as well, such as: · Transistors for power supply using MOSPET technology · Gold-plated screw connectors for loudspeaker and power supply · Bass-Boost To achieve the best possible sound quality from your new Velocity Amplifier we recommend that it is installed by an authorised Velocity dealer and that the matching Velocity Loudspeaker system is used. This is the way to obtain the full enjoyment of the performance of your amplifier. [. . . ] 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. use cable bushings at sharp-edged holes. Use loudspeakers with 2-4 ohm impedance. Do not connect the loudspeakers to earth, use only the designated terminals. The cross-section of the positive and negative cable may not be less than 16 mm2. Preamp-INPUT Please use high-quality Velocity cinch/RCA cables for connecting the pre-amp input for right and left channels. 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. This causes each subwoofer to be decoupled in an optimum fashion. 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 assigned to the rear inputs (CH3 and CH4). 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. [. . . ]
