Observe these reference notes by any means, otherwise damage of the device or the vehicle may be caused. Furthermore serious injuries may be caused by not following these reference notes. In vehicles with a newer year of manufacturing (since approx. [. . . ] Automatic antenna) or the turn-on remote signal of your headunit with the REM-terminal of the amplifier. Use therefor a suitable cable with a sufficient cross section (0, 5 mm2). Thereby the amplifier will turn on or off automatically with your headunit. GND Connect this GROUND terminal with a suitable contact ground point on the vehicle's chassis. The ground wire must be as short as possible and must be connected to a blank metallic point at the vehicle's chassis. Ensure that this ground point has a stable and safe electric connection to the negative "­"pole of the battery. Check this ground wire from the battery to the ground point if possible and enforce it, if required. Use a ground wire with a sufficient cross section (at least 10 mm2) and the same size like the plus (+12V) power supply wire. Observe while installation not to lead the audio cables between the headunit and the amplifier together with the power supply wires on the same side of the vehicle. This stands also for the equipped bass-remote wire, which should be installed not together with the power supply wires, but rather with the audio signal cables. The LINE INPUT RCA jacks must be connected with the RCA output jacks of the headunit. The MODE switch enables in switch position MONO, that only one RCA jack with a mono audio signal needs to be connected on LINE INPUT CH L. Chose this mode only, if you want to run the amplifier with a subwoofer in the LOW PASS mode. The INPUT LEVEL controller adjusts the input sensitivity of the amplifier to align the audio signal from the head unit. The HIGH PASS controller works in the LP/BP mode as subsonicfilter and eliminates the lower frequencies (Bandpass-Mode). NOTE: If this controller is turned to a higher value than the lowpass controller, no sound is hearable. ) The HIGH PASS controller works in this operation mode as subsonicfilter and eliminates the lower frequencies (Bandpass-Mode). NOTE: If this controller is turned to a higher value than the lowpass controller, no sound is hearable. Connect the RCA lineouts of the headunit with the RCA jacks LINE INPUT of the amplifier with appropriate high-value RCA cables. ⷠIn the lowpass mode (LP/BP) the HIGH PASS controller works also as subsonicfilter, that eliminates the ultra-low, not hearable and harmful frequencies to generate a bandpass signal (Bandpass mode). The subsonic frequency should be set between 15 to 40 Hz, depending on the size of the subwoofer. NOTE: If this value is higher than the lowpass setting, no sound is hearable. [. . . ] ELECTRICAL INTERFERENCES The reason for interferences are mostly the passed cables and wires. Especially the power and audio cables (RCA) of your sound system are vulnerable. Often these interferences are caused by electric generators or other electrical units (fuel pump, AC etc. The most of these problems can be prevented by a correct and careful wiring. [. . . ]
