[. . . ] As innovators in the world of car hi-fi, we are pleased to introduce you to the new future-oriented technology that is integrated in our Class D amplifiers. Class D amplifiers are considerably more efficient than standard analogue technologies. The efficiency of analogue amplifiers is around 60 % whilst our digital power amplifiers convert up to 80 % of the input energy into sound. You could describe the results as "more sound produced from less". [. . . ] To ensure that the sound quality is optimised, we recommend that the installation of your new Velocity amplifier be carried out by an authorised Velocity dealer. Please allow us to make a few comments on the issue of health: When listening to music in your vehicle, remember that continuous sound pressure levels of over 100 dB can lead to permanent hearing damage and even total hearing loss. Modern high-powered systems and high-quality loudspeaker configurations are capable of producing sound pressure levels exceeding 130 dB. We are convinced that you will very quickly appreciate the advantages of our Class D amplifiers and we would like to take this opportunity to wish you a lot of fun with this new component in your sound system. We provide a manufacturer guarantee for our products bought within the European Union. You can view the guarantee conditions at www.

It is very important that you take into account the specifications of the loudspeakers being used whilst you are adjusting the crossover. Crossover frequency control (LOW PASS + HIGH PASS) If the crossover is activated (LP or HP) by adjusting the position of the crossover switch, you can then use the corresponding control to adjust the crossover frequency of the respective filter to anywhere between 40 Hz and 160 Hz or 40 Hz and 600 Hz (i. Settings for a subwoofer In order to obtain the best sound when a subwoofer is connected, the subwoofer must be separated as far as the frequencies it receives are concerned, i. It must only be fed with low frequencies (bass). Firstly, turn down the LEVEL control on the amplifier to minimum and set the LOW PASS frequency control to its centre position. Now play some music on your car sound system that you are very familiar with and that contains some low bass (e. Now slowly increase the volume of the subwoofer by turning the LEVEL control on the amplifier in a clockwise direction until you feel that the sound of the music is well balanced, i. The bass is neither too weak nor overpowering. Now listen to the relationship between deep male voices and the upper bass and also take note of the relationship between the upper bass (kick bass) and the lower bass. The bass should ideally sound crisp and have a clear low bass component, and male voices should neither sound too weak nor should they billow out. You can stop making adjustments if you are happy with the sound. [. . . ] You can stop making adjustments if you are happy with the sound. If male voices seem to billow out or the low bass is too weak, you should turn the LOW PASS frequency control slightly towards minimum and then continue making your adjustments as described in point 2 onwards. If the bass sounds low but dirty and booming or the male voices sound too weak, you should turn the LOW PASS frequency control slightly towards maximum. Next, continue making your adjustments as described in point 2 onwards. [. . . ]
