Installing the BRAX Amplifiers In order to maintain the quality of this product and ensure 1. safe operation, we recommend that our amplifiers be Install your amplifier at a dry location in the car where installed by an authorized BRAX dealer. Installation by a there is sufficient air circulation to ensure adequate cooling qualified and accredited technician will qualify you for our of the equipment. Also ensure that there is sufficient clearance special lifetime warranty.
Installation and Connection of BRAX Amplifiers X 1400 and X 2400 The above amplifier models may only be installed in In order to avoid cross-talk distortion, audio cables should motor vehicles which have a 12-volt negative terminal never be laid together with electrical leads (with the excep- connected to the chassis ground. Any other system could tion of the screened BRAX POWER TRAX power supply cause damage to the amplifier and the electrical system of cables). the vehicle.
Connection of the Power Supply The +12 volt power supply cable (see Fig. 2) should be Fig. 2 connected directly to the positive terminal of the battery. A fuse should also be provided at a distance of max. 30 cm from the battery. The amperage rating of the fuse is calculated from the maximum total current input of the car/vehicle hifi system. The fuse holder appertaining to the amplifier is supplied with the amplifier module. This must be installed at 4 a distance of max.
Connection of the Speaker Cables Important! Fig. 5: 2-Channel Mode Never connect the speaker cables to the vehicle chassis. This can destroy your amplifier. Ensure that all the speaker Mono Input Mono Input Front right Rear right systems are connected in-phase, i.e. plus to plus and minus to minus. The positive terminal is indicated on most speakers. In addition, the amplifiers may be operated in 2-channel mode (see Fig. 5), 3-channel mode (see Fig. 6) and 4-channel mode (see Fig. 7).
Circuit Control Cards The operating range of the amplifier is determined by Example: If you wish to use the module as a subwoofer replaceable Circuit Control Cards (CCC). If no special amplifier, with the subwoofer being operated at 90 Hz, you requirements regarding the CCC’s are specified when find the corresponding Circuit Control Card from the list ordering, the amplifier is supplied as standard with CCC 1.
