Resumen del manual
REM / 12V / GND: -REM: Connects to a 12V+ switched source. The REM cable should have 12V when the source unit is on and 0V 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.

The diagnostic system will not shut down the HDBR or the amplifier(s), although the amplifier(s) own protection circuitry may shut the amplifier(s) down should a fault status occur. At which time you will need to consult the owners manual for that particular amplifier. Low output power 1 - Check that level controls have been set up properly. 2 - Make sure that the battery voltage, as measured at the amplifier(s) and HDBR +12 volt and ground terminals, is 11 volts or more. 3 - Check all +12 volt and ground connections. Fuses blowing 1 - Insure that the voltage to the unit does not exceed 15 volts. 2 - A short on the main +12 volt cable from the battery to the vehicle chassis will cause the main fuse to blow. 3 - If the MBC1 is blowing fuses continually with only +12 volt, ground and remote leads connected, the unit may be faulty. System does not turn on 1 - Check all fuses. 2 - Check all connections. 3 - Measure the +12 volt and remote turn on voltages at the amplifier(s) and HDBR terminals. If these are non existent or low, take voltage measurements at fuse holders, distribution blocks, the head unit’s +12 volt and remote leads to localize the problem. Noise problems System noise can be divided into two categories, 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 HDBR Input RCA’s, and if the hiss level reduces, the source unit is 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 just a few, create radiated electrical fields, as well as noise on the +12 volt supply and ground. To try and eliminate this noise, run a wire from the radio ground wire to the ground input on the HDBR. A ticking or whine that changes with engine RPM: 1 - This problem could be caused by radiation pickup of RCA cables that are too close to a fuel pump or a distributor. 2 - Check that the head unit ground is connected straight to the vehicle chassis, and does not use 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. A constant 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 - Check all connections, especially for good grounds. 2 - Make sure that no speaker leads are shorting to exposed metal on the vehicle chassis. 3 - RCA cables are notorious for their problematic nature, so check that these are good, in particular the shield connections. 6 As the manufacturer of Maxxsonics, MB Quart, Hifonics, Crunch and Autotek car audio products, Maxxsonics USA Inc.
