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.
