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 bridging module or not. If the settings are in the wrong position, the amplifier may not work.

There are three settings for this control: Master 0, Master 180, Slave. Use the following to determine what position to set your amplifier in. For further reference, please review the drawings following.

Master 0: this setting will maintain the same phase as the signal applied to it.

1.Use this setting if the amplifier is not bridged with another amplifier.

2.When bridging the amplifiers, use this setting only on the amplifier that is connected to the head unit. Master 180: this setting will reverse the phase 180degrees of the signal input into the amplifier.

1.Use this setting if the amplifier is not bridged with another amplifier and the subwoofer(s) are out of phase with the satellite speakers in the vehicle.

2.When bridging the amplifiers, use this setting only on the amplifier that is connected to the head unit. Only apply this if the subwoofer(s) are out of phase with the satellite speakers in the vehicle.

Slave: this setting limits the controls of the secondary amplifier in a bridged pair.

1.Use this setting only on the second amplifier in a bridged pair. All crossover, subsonic and level controls of this amplifier will be removed. The amplifier set on one of the two Master settings will then control each of the preamp functions for both amplifiers.

HOW TO BRIDGE MY AMPLIFIERS

Bridging the two like amplifiers together is fairly easy. Please follow the following diagram to assure proper connections. If you are experiencing any difficulties, please contact Crossfire's technical department at 562-483-8111.
