PASSIVE AND ELECTRONIC CROSSOVERS

Your REFERENCE amplifier is unique in its ability to switch between Coherent StereoTM , Bridged Mono, and Mixed Mono output mode. The REFERENCE ampliiiers are capable of driving a complete subwoofer and satellite system in the Mixed Mono conliguration. However, lor lowest distortion, maximum output, and best sound quality, we recommend that you use an electronic crossover and multiple channels of amplilication.

If a single REFERENCE amplifier is to drive a subwoder and satellite system, passive high and low pass crossovers will be necessary. Use the charts on pages 7 and 8 to determine the values of the crossover components.
