User manual HELIX P200

[. . . ] This is performed by means of four fixing screws screwed into a mounting surface offering sufficient retention and stability. Before drilling the holes for the screws, carefully examine the area around the installation position and make sure that there are no electrical cables or components, hydraulic brake lines or any part of the petrol tank located behind the mounting surface - otherwise these could be damaged. You should be aware of the fact that such components may also be concealed in the double-skin trim panels/mouldings. General instruction for connecting the amplifiers The HELIX amplifiers may only be installed in motor vehicles which have a 12-volt minus pole connected to the chassis ground.

This connectors are gold-plated to ensure a better signal transmission. 8-9 Level controls for input sensitivity These controls can be used to match the input sensitivity of the individual channels to the output voltage of the connected head unit. These controls are not volume controls and are solely intended for the purpose of sensitivity trimming. 10 Selector switch for channels A and B To switch the internal active crossover to highpass/full range (linear) or lowpass.
