MASTER INVERT LOW IN LINE OUT HPF FULL LPF OFF ON SLAVE 0 180 R IN OUT REMOTE SUB 50 250 L CROSS LEVEL OVER SONIC LPF The BMF1000D and the BMF600D will reach their potential output into a 1ohm load. However, a lower impedance can send the amplifier into current protection and possibly damage the circuitry. To prevent damage, use the following formulas to help you figure out the load you are placing on the amplifier. If you have any difficulties, please contact your local C

POWER WIRE & FUSE The proper wire size is very important for an amplifier capable of these power levels. The following are the recommended fuse values and wire gauge for lengths up to 20ft. Model Wire Fuse BMF1000D 4awg. 100amp BMF600D 8awg. 60amp POWER Power wire needs be connected directly to the battery using the wire requirements listed above. Never use the fuse box or any other wire as a source for the power for an amplifier. Before you start, choose the easiest path to

SPEAKER OUTPUTS SPEAKER OUTPUTS WIRING Due to the power output and the low frequency bandwidth of the Class "D" amplifiers, Crossfire recommends using a minimum of high quality 12 gauge speaker wire. Consult your local dealer for their recommendations. As with the power wires, use caution around sharp corners or body parts that may easily cut through the insulation on the wire. To connect the wire to the speaker, strip off approximately ½" (12mm) of the insulation and terminate the wires usin

P PEAMP FEA EAMP FEAT TURES URES The Crossfire BMF600D and BMF1000D have a tremendously powerful preamp section located on the panel opposite the power terminals. Included in this preamp section are Lowpass Crossover for the amplifier, a switchable/variable Subsonic Filter, Preamp Output with Variable Crossover, a Digital Remote Level Control, and a built in Bridging Module. These features can be used to improve your system quality an as well as make the amplifiers easier to use on a day to

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 should only be done if the proper impedance cannot be achieved with the amplifiers separated. It is very important to set the Master/Slave control on the amplifier whether you are using the br

GAIN CONTROL Located in the preamp section on the side panel of the amplifier is the gain control (marked level). This control allows you to match the input level of the amplifier to the output level of your source unit or signal processor. Matching the input can be accomplished in three simple steps: 1. Turn gain control all the way down. 2. Turn on the source unit and adjust to 2/3 of max volume. 3. Adjust the gain control until desired volume is achieved without audible distortion Reme
