3. hiss and electrical interference Hiss or white noise 1 High levels of white noise usually occur when level controls are turned up too high reduce the levels until the noise is no longer present 2 Another major problem that can cause excessive hiss is a noisy head unit unplug the Input RCA and ifthe hiss level reduces the source unitis at fault Electrical interference The inside of an automobile is a very hostile electrical environment The multitude of electrical systems such as the ignition system alternator fuel pumps air conditioners to mention justa few create radiated electrical fields as well as noise on the 12 voltsupply and ground To try and eliminate this noise run a wire from the radio ground wire to the ground inputon the A ticking orwhine thatchanges with engine RPM 1 This problem could be caused by radiation pickup of RCA cables thatare too close to a fuel pump ora distributor 2 Check thatthe head unit ground is connected straightto the vehicle chassis and does notuse factory wiring for ground 3 Try to supply the head unit with a clean 12 volt supply directly from the battery instead of using a supply from the in dash wiring fusebox Aconstant whine This type of noise can be more difficult to pinpoint but is usually caused by some kind of instability causing oscillations in the system 1 Checkall connections especially for good grounds 2 Make sure thatno speaker leads
4. SWITCHING THIS SELECTION RCA INPUT In most cases you will leave the selection switch in the BALANCED position In some systems the source unit may look for a ground through the RCA connections In this event you would switch the selection to UNBALANCED INPUT RCA s from source unit connect to this location OUTPUT from the connect to the inputs of your amplifier s REMOTE The BPR 1 Bass Processor Remote dash mount control connects here This remote allows for complete control of your audible subwoofer level along with a LED indicator which brightens as you increase bass enhancement REM 12V GND REM Connects to a 12V switched source The REM cable should have 12V when the source unit is on and OV when the source unit is off Typically this would connect to the Power Antenna output wire on the back of your source units wiring harness 12V Connects to a 12V constant source The Positive battery terminal is recommended and a 1 amp in line fuse is required GND Connects to a ground location Be sure that all paint is removed from the area of this connection on the vehicle chassis TU HDBR WIRING DIAGRAM Source Unit HDBR DIGITAL BASS RESTORATION OUTPUT LEVEL FREQUENCY CENTER GROUND E FREQUENCY ISOLATION GROUND Ohms ISOLATED RCA INPUT BALANCED UNBALANCED o WIDE NARROW Bgm REMOTE TURN ON TO BATTERY 12v VIA
