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.
