User manual BRAX X 2400.2

[. . . ] For safety reasons, the amplifier must be secured in a professional manner. 1) screwed into a mounting surface offering sufficient retention and stability. Before drilling the holes for the screws, carefully examine the area around the installation position and make sure that there are no electrical cables or components, hydraulic brake lines or any part of the petrol tank located behind the mounting surface - otherwise these could be damaged. [. . . ] 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. 5 CPS-Colour Protection System This shows the operating status of your amplifiers. When the amplifier module is switched on, both LED's change to green. Green = operational; Red = malfunction in the amplifier, short circuit at the speaker output; overheating. If the amplifier has tripped owing to overheating, it may take some time, depending on the ambient temperature, before it is re-activated. Position 1 - STEREO: If the amplifier operates in 2-channel mode the switch has to be set on stereo position and both inputs (1 and 2) must be used. position 2 - BRIDGED-STEREO: If the amplifier operates in Mono mode the switch has to be set on Bridged position. On the position , , Bridged" both inputs A and B (1 and 2) must be used. Position 3 - BRIDGED-MONO/CHL: As on position , , BRIDGED-STEREO" the amplifier operates in Mono mode where both channels work as one (Mono) channel. 12 Lowpass/Bandpass Frequency Selector To switch the control range of the potentiometer (14) from 15 Hz to 300 Hz and from 250 Hz to 4500 Hz. 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. 13 Highpass Frequency Selector To switch the control range of the potentiometer (15) from 15 Hz to 300 Hz and from 250 Hz to 4500 Hz. If this selector is set on Highpass, the frequency range can be adjusted with selector 13 and the exact frequency can be adjusted with control 15. With selector 13 and control 15 adjust the Highpass and with selector 13 and control 14 adjust the Lowpass. Thus every desired Bandpass between 15 Hz and 4500 Hz can be adjusted. [. . . ] 6 Input Sensitivity Level Controllers The level controllers enable the input sensitivity of the BRAX amplifiers to be adapted to the output voltage of the connected control unit (radio/tuner). 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. If a subwoofer is connected we recommend to use highpass control 20 as variable subsonic filter or to turn control 20 counter-clockwise to 15 Hz to get a subsonic filter. [. . . ]
