Ensure that all the speaker systems are connected in-phase, i. e. The positive terminal is indicated on most speakers. In addition, the amplifiers may be operated in 2-channel mode (see Fig. The mono/stereo selector switch is located at the bottom of the amplifier. 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). If CCC 1 is inserted at socket position 1 or 2, as described in Fig. 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. Handling the Circuit Control Cards Removal of a Circuit Control Card 1.
