[. . . ] This is the way to obtain the full enjoyment of the performance of your amplifier. Let us finally mention the aspect of health safety. Please remember when listening to music in your car that constant sound-pressure levels of more than 100 dB can cause permanent damage to the human ear right up to complete loss of hearing. [. . . ] 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 10 mm2. Fit a fuse holder to the positive cable between the battery and the amplifier directly at the battery. Allows you to drive two loudspeakers (4 ohm) and to connect a third speaker (4 ohm) in mono operation (bridged mode). positive/negative connections We recommend a minimum cross-section of 10 mm2. Lay commercially available positive cable to the battery and connect using fuse holder. The fuse holder should be connected close to the battery. use cable bushings at sharp-edged holes. Screw the commercially available negative cable firmly to an interference-free earthing-point (car body bolt, car body sheet, but not to the negative battery pole). Scrape the contact surface of the earthing point until it is blank metal and coat with graphite grease. +12V Controller (GAIN) Using the Gain Controller you can adjust the input sensitivity of the Velocity Power Amplifier to the output voltage of your car radio preamplifier output. When connecting a car radio from other manufacturers the input sensitivity should be adapted in accordance with the specifications of the manufacturer. 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). [. . . ] Crossover frequency controller (LP) If the frequency divider (low-pass) has been activated using the crossover switch, then it is possible to adjust the crossover frequency of the relative filter between 35 Hz and 250 Hz in infinitely variable stages. This controller has no function when the unit is set to Full Range mode. 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. [. . . ]
