[. . . ] When drilling holes, you must make sure that none of the vehicle components (e. When choosing an installation location, you should select one which is dry and which provides sufficient air circulation to cool the amplifier. Do not connect loudspeakers to earth ­ only use the correct terminals as indicated. The cross section of the positive and negative cables must be at least 8 mm2.

Securely screw a standard 8 mm2 negative cable to an interference-free earth connection point (bolt connected to the car body, car body sheet metal) ­ though do not connect it to the negative terminal of the battery. Scratch the surface down to the bare metal at the point at which the earth contact is made and apply graphite grease. 5 The switching line must be connected when connection is carried out +12V using the RCA jacks or the loudspeaker jacks of the car radio. LEVEL control You can use the LEVEL control to adjust the input sensitivity of the Velocity power amplifier to the output voltage of your car radio's preamp output. When connecting a car radio produced by another manufacturer, you must adjust the input sensitivity in accordance with the information provided by the manufacturer. This gives you the convenience of controlling the bass level remotely (see Fig. If you want to use the remote control, the device must be operated with the low-pass filter activated (Crossover (FILTER) switch set to position LP). oUTPUT Outputs for connecting an additional amplifier (formation of chains of amplifiers). LP / HP / FULL switch Before installing, adjust the Crossover (FILTER) switch on the power amplifier to set the low pass filter (LP), high pass filter (HP) or full range (FULL). If you select the FULL position, the full frequency response will be used at the output. Using the integrated Crossover (FILTER)s is particularly useful in the case of multi-channel sound systems with a separate 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. To ensure that this is the case, select LP and use the Crossover (FILTER) 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 Crossover (FILTER) 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 Crossover (FILTER), 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 Crossover (FILTER). Crossover (FILTER) frequency control (LOW PASS + HIGH PASS) If the Crossover (FILTER) is activated (LP or HP) by adjusting the position of the Crossover (FILTER) switch, you can then use the corresponding control to adjust the Crossover (FILTER) frequency of the respective filter to anywhere between 50 Hz and 250 Hz or 50 Hz 4 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 can be adjusted in order to protect the subwoofer against mechanical overload due to low bass frequencies that fall outside our hearing range. 2a The fuses that are integrated in the amplifier protect the power amplifier and the entire electrical system in the event of a fault. If the fuse needs to be replaced, never bypass/bridge the fuse and never replace it with fuse types that are designed for higher currents.
