User manual BLAUPUNKT TP E2 W/R GB

[. . . ] Observe the maximum load rating (music power rating). use loudspeaker connection cables up to 16 mm2. Do not connect loudspeakers to ground - only use the correct terminals as indicated. The cross section of the positive and negative cables must be at least 25 mm2. [. . . ] Congratulations on purchasing this high-quality car audio subwoofer amplifier. 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 95 % of the input energy into sound. You could describe the results as "more sound produced from less". Furthermore, digital amplifiers heat up so little that they can also be installed in places that are not very well ventilated, such as beneath the seats. The wire remote control that is included allows you to adjust the bass level conveniently from your seat. 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 highquality 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. Now listen to the relationship between deep male voices and the higher bass frequencies 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 LP-FREQ 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 LP-FREQ control slightly towards maximum. Furthermore, you should set the phase control so that the upper bass sounds as powerful as possible. Next, continue making your adjustments as described in point 2 onwards. If you want to precisely optimise the acoustic settings of the crossover, 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. Bass boost You can adjust the bass output of the Velocity amplifier using the bass boost control. It can be adjusted in order to protect the subwoofer against mechanical overload due to low bass frequencies that fall outside our hearing range. [. . . ] Note: You must make sure that the fuse holder is protected effectively against moisture. Note: In the case of longer supply lines to the vehicle battery, a second battery can be installed alongside the amplifier in order to stabilise the voltage. this must be installed by a professional workshop. Use cable grommets to protect cables against sharp-edged holes. [. . . ]
