Description
Use KEYLOC when the factory signal needs more than a basic speaker-to-RCA conversion. It analyzes a two-channel OEM feed and corrects factory EQ, crossover, time-delay and all-pass behavior so the aftermarket amp or processor gets a cleaner signal to work with. Choose a basic LOC when the factory signal is already usable; move to a full DSP/OEM-integration platform when the system needs multi-channel summing, independent tuning or vehicle-data integration. KEYLOC is a powered 2-channel smart LOC, not an amplifier or full-system DSP.
Where this fits in the build
This is a system-control or DSP component. The correct choice depends on the signal path, channel count, routing, retained features and the rest of the amplifier and speaker plan.
