The battery's negative terminal must be disconnected for the entire time it takes to install and connect the device. [. . . ] It must only be fed with low frequencies (bass). To ensure that this is the case, select LP and use the XOVER frequency control to adjust the upper frequency to between 50 Hz and 250 Hz. This ensures that every subwoofer is optimally separated as far as the frequencies it receives are concerned. If HP is selected, you can use the associated XOVER frequency control to adjust the lower cut-off frequency to between 50 Hz and 250 Hz. If you want to precisely optimise the acoustic settings of the XOVER, we recommend you obtain advice from a Velocity dealer. It is very important that you take into account the specifications of the loudspeakers being used whilst you are adjusting the XOVER.

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 GAIN 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 GAIN 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. 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. If you want to precisely optimise the acoustic settings of the XOVER, we recommend you obtain advice from a Blaupunkt dealer. It is very important that you take into account the specifications of the loudspeakers being used whilst you are adjusting the XOVER. The cross section of the positive and negative cables must be at least 12 mm2. [. . . ] If amplifier performance temporarily declines, then you know that you are running your system at its limits, but can nevertheless rest secure in the knowledge that it will not abandon you by cutting out entirely. Using the connecting rails, you can install several amplifiers next to one another to form a cool multichannel monster system with a convincing look. An additional advantage of the connecting rails and side pieces is plenty of storage space for avoiding messy bunches of cables.
