User manual BRAX X 1400

[. . . ] Once again we would urge you to have the installation work carried out by a specialist, as verification of correct installation and connection of the unit is a prerequisite for warranty cover of the BRAX by AUDIOTEC FISCHER Germany. 1. Install your amplifier at a dry location in the car where there is sufficient air circulation to ensure adequate cooling of the equipment. Also ensure that there is sufficient clearance available for making the cable connections and operating the controls. For safety reasons, the amplifier must be secured in a professional manner. [. . . ] The fuse ratings are: for amplifier X 1400 = 60 A, for amplifier X 2400 = 100 A. 2) should be connected to the central ground reference point (this is located where the negative terminal of the battery is grounded at the metal chassis of the vehicle), or to a bright bare-metal location on the vehicle chassis, i. e. It must be ensured that resistance values to the power sources (alternator, generator, battery) are minimized as excessive resistance can appreciably affect the audio quality and dynamics of the system. 2) is connected to the , , Remote" connection or the automatic antenna connection of the control unit (tuner/radio). The antenna connection is only activated if the control unit is switched ON. This ensures that, with the control unit switched off, the amplifier is also switched off to safe the battery.

The function of the switch is described on a label at the bottom of the amplifier (see Fig. 5: 2-Channel Mode Mono Input Mono Input Position of selector switch at the bottom of the amplifier: Rear = Mono Front = Mono (see Fig. 6: 3-Channel Mode Mono Input Rear right Position of selector switch at the bottom of the amplifier: Rear = Mono Front = Stereo (see Fig. 7: 4-Channel Mode Position of selector switch at the bottom of the amplifier: Rear = Stereo Front = Stereo (see Fig. 4) 6 Circuit Control Cards The operating range of the amplifier is determined by replaceable Circuit Control Cards (CCC). If no special requirements regarding the CCC's are specified when ordering, the amplifier is supplied as standard with CCC 1. CCC 1 is plugged in at socket position 3 which means that the amlifier is operating in the full range (see list on page 8). 8 to 12, the amplifier operates with a subsonic filter having a rate of change of 18 dB/Oct. The various Circuit Control Cards available are indicated in the list on page 8. Example: If you wish to use the module as a subwoofer amplifier, with the subwoofer being operated at 90 Hz, you find the corresponding Circuit Control Card from the list (in this case CCC 5) and insert the card in your BRAX amplifier at position 2 of that channel which is to control the subwoofer - the right channel in the case of the mono mode (bridge mode). Now the amplifier will only process frequencies up to 90 Hz, with any frequencies above that value being suppressed at the rate of change of 18 dB/Oct. At position 1 the amplifier will only process frequencies higher than 90 Hz.

Optimum setting of the level controller ensures you maximum audio enjoyment without those all-too-common audible distortions and overshoot phenomena which have such an adverse effect on sound quality. 6 Power Supply Terminal Terminal for connecting the positive 12-volt power supply cable, the ground/chassis lead and the remote lead. 7 External Connection for a BRAX Power Stabilizer 8 Power ON and Protection LEDs The power ON LED lights up green when the amplifier is switched on. In the event of one of the two channels overheating, the LED switches to red. [. . . ]
