The F4 are complete amplifiers, rich with useful devices 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 Watt… so much energy for those who have "bad intentions!"

F4 600 is usable in mono bridged like all Twister amplifiers, delivers 2x460 Watt RMS @ 4ohm, or in 3 channel configuration to excellently drive a system front+sub with a power of 2x145 + 1x460 Watt RMS at 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 current and power-on transients, are continuously monitored. It is a system that controls the rotation of the cooling fan, varying its speed as the heatsink temperature varies. Directly linked to GPS, it guarantees the most effective heat dissipation generated.

| THERMOSPEED | Active Forced-cooling System

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

| E.NO.DE. | Electromagnetics Noise Destroyer

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