Biamping with an external crossover

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

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

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

Make sure that the crossover point of your active crossover is adjusted to match the crossover point of your speakers. Consult your speaker and crossover owner's manuals.
