What sets FUSION apart?
The FUSION FM series amplifiers come complete with FRAT power supplies, FIST cooling system and FUTRANZ. Also
all marine amplifiers use heat-tempered PCB’s for maximum product life and performance. Gold plated connectol-
ogy, ensures your signal flows from the head unit through to the speakers with as little injected distortion and
noise as possible. This results is a very clean and very powerful reproduction of the input signal. All these features
make it easier to achieve sonic perfection in almost any installation.
FUTRANZ
In developing extremely powerful amplifiers, it is essential to keep things cool so FUSION developed a heat sink
that has a heat dissipation ability like never before. This was not an easy task but none the less it was achieved,
another important factor is efficiently transferring the heat from the semi-conductors to the heatsink, conven-
tional designs use a white paste as the interface between these devices and the heatsink, this is not a perfect
solution when complete surface coupling is required. So all Marine Ampliers come equipped with a composite heat
transferring tape. Core heat in semi-conductors causes distortion and poor component performance characteris-
tics. Testing has shown a massive reduction in core heat has been achieved by using the FUTRANZ heat transfer-
ring technology. In simplified terms this means excellent thermal stability and maximum component reliability.
F.I.S.T
(fusion intercooled semi-conductor technology)
FIST is an innovative method of clamping down all internal power switching and audio output devices with an
aluminium extrusion that has extremely low temperature co-efficiency. By using F.I.S.T it creates the perfect cool-
ing solution, rapidly removing core heat from all associated semi-conductors from both sides of the device at once
resulting in extremely low distortion an excellent thermal stability
F.R.A.T
(fusion intercooled semi-conductor technology)
FRAT is a regulated amplifier design, FUSION regulated amplifiers allow an enormous amount of output power at
the lowest voltage (12.6 Volts) and extreme output at 14.4 volts.
