Biamping with an external crossover

If you have an external active crossover, you can greatly increase the efficiency of your system. The crossover will split the preamplifier output signals into two frequency ranges.

You can connect the crossover's low frequency outputs to the ampli- fier's rear channel inputs, and the crossover's higher frequency outputs to the amplifier's front channel inputs.

This is an efficient system because the channels only amplify signals with- in the frequency range of the speaker element they are driving. Little power is wasted.
