User manual HELIX P12 DATASHEET

[. . . ] The unique unit design with its PCB gold-plated on both sides, the consistent employment of carefully selected high-end components, mechanical components of uncompromising quality and a switched power pack for controlled power supply guarantee maximum audible enjoyment of the highest standard without loss and without distortion. In order to facilitate easy operation of the HXE 100 after installation, the frequently employed controls and switches have been located on the front panel. To extend the controls for easy operation, press them gently and allow them to protrude. Once the adjustment has been made, press them again and they will be returned to their flush position so as to prevent any accidental maladjustment. [. . . ] The other controls required for the basic settings are concealed for the same reason. The controls for adjusting the cutoff frequencies can be adjusted with ease from the front using the enclosed screwdriver. The individual input gain controls are adjusted from above so that, at full loudness volume of the HXE 100 (Note! 7 volt output) , the downstream components , and particularly the speakers , still remain undamaged. The ILL switch enables the color of the unit illumination to be changed from green to amber. This allows the unit to be adapted to virtually any vehicle interior. Installation In order to be able to operate the HXE 100 with ease, install it at a location which ensures good visibility and accessibility. Make sure that it is firmly fastened in position (using the enclosed fixing materials) and that there is sufficient space for connecting the cables to the rear of the unit. In addition, the HXE 100 should not be installed too close (leave at least 15 cm) to sources of interference such as the ignition coil. As the unit does not require any special cooling, it can be located where space is tight, subject to the above conditions being met. With the volume control at maximum, determine the maximum gain by gradually turning the input gain controls in a clockwise direction. It must be ensured that no distortions occur and that all the other components are neither electrically nor mechanically overloaded. Please protect your hearing as the output of HXE 100 is capable of driving your components to the very maximum of their output rating and loadability. By adopting the same procedure, you can use the separate controls at your AUX input in order to adjust the volume of your auxiliary equipment (e. Adjust your volume controls on the radio and auxiliary equipment so that the volume of your complete system can be adjusted using just the volume control of the HXE 100. This minimizes any interference which may occur and substantially improves the sound output of the system. You can adjust the subwoofer pre-amplifier using the SUB Volume control. First, however, adjust the transition frequency of the integrated subwoofer crossover to the optimum setting as described above using the screwdriver supplied so as to rule out the possibility of any subwoofer boom. Where the subwoofer cannot be localized. The SUB Volume control should then be adjusted so that the bass is at a level suitable for other music reproduction. [. . . ] Where the subwoofer cannot be localized. The SUB Volume control should then be adjusted so that the bass is at a level suitable for other music reproduction. Of course, this control can also be used while driving to adjust the bass independently of the fader to compensate for travel noise and to satisfy your own preferences. the equalizer serves to optimize the overall frequency profile.
