The F4 are complete amplifiers, rich in devices useful for managing the most sophisticated system types. Structured in two sections, they have separate inputs to be used in a unified or independent way, each section is equipped with ultra-flexible electronic crossovers, capable of interpreting configuration needs both in multiway systems and in multi-amplified ones. The three models, different in power, are all usable in mono, bridged; the integrated fans contribute to increasing the performance that in the F4 600 is expressed in over 1200 Watts… so much energy for those who have "bad intentions!"

F4 380 is usable in mono bridged like all Twister amplifiers, delivers 2x290 Watts RMS @ 4ohm.

INTEGRATED TECHNOLOGIES

| GPS | Global Protection System

GPS includes a series of devices dedicated to the global protection of the amplifier and speakers. Short circuit and overheating, DC output and power-on transients, are continuously monitored. It is a system that controls the rotation of the cooling fan, varying its speed as the heat sink temperature varies. Directly linked to GPS, it guarantees the most effective dissipation of the heat generated.

| THERMOSPEED | Active Forced-cooling System

It is a system that controls the rotation of the cooling fan, varying its speed as the heat sink temperature varies. Directly linked to GPS, it guarantees the most effective dissipation of the heat generated.

| E.NO.DE. | Electromagnetics Noise Destroyer

The input circuitry of the Twister is immune to interference generated by the vehicle's electrical system. ENODE eliminates ground loops, promoting installation speed and guaranteeing impeccable reproduction.
