PASSIVE AND ELECTRONlC CROSSOyERS

Your Granite amplifier is capable of driving a complete subwoofer and satellite sys tern in the Mixed Mono configuration. However, for the lowest distortion and the max- imum output and sound quality, we recommend that you use electronic crossovers and multiple channels of amplification, as provided in the Granite 120.4 and the Granite 180.6.

If only two channels of your Granite amplifier are going to be used to drive a sub woofer and satellite system, passive high and low pass crossovers will be neces- sary. Use the following charts to determine the values of the crossover components.

KfY L = high quality (DCR < 1 Ohm) inductor/coil

C = nonpolarized 50v (or greater) capacitor
