OPERATION
OPERATION
Both the Crossfire BMF1000D and BMF600D are single channel, dedicated subwoofer amplifiers. Unlike other Crossfire BMF amplifiers, both these amplifiers operate
as a single channel, therefore one amplifier cannot be bridged by itself. Do not be fooled by the two sets of speaker outputs. Two outputs are provided strictly for
convenience and are paralleled internally on the circuit board of the amplifier. This means that if both outputs are used with one driver each, the amplifier sees the
same load as if the same two drivers are connected to only one output terminal.

LOWPASS CROSSOVER Locate the rotary dial marked LPF. This is the LowPass Filter (crossover) for the amplifier. The lowpass crossover points are fully variable from 50Hz to 250Hz making them ideal for subwoofers. Adjust this dial either to the recommended crossover frequency for the subwoofer or, mor...
BRIDGING CIRCUIT (Invert output) The bridging module can only be used when two pairs of either BMF600D or BMF1000D are used. This allows for the two amplifiers to be run in series to achieve double the output. However, this does change the minimum impedance required to 2ohms. Bridging the amplifiers...
