High End 4-Channel Car Amplifier

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 descri-
bed in Fig. 8 to 12, the amplifier operates with a subsonic
filter having a rate of change of 18 dB/Oct. from 45 Hz.
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
Inserting the Circuit Control Card
1. Choose the position number from the CCC list which
corresponds to the required function of the amplifier, and
insert the card in the base so that the position number on
the card is located at the top at the housing cover next to
the arrows according to the channels (see Figs. 11 and 12).
2. Insert the card at an angle of approx. 15°
so that it fits properly into the socket.
Press the card between the clips so that
it is secure in the base (Fig. 10).
2. Tilt the card approx. 15° in order
to detach it from the base (see Fig. 9)
