◆ RTP (Real Time Protection)
NOMAD (NOn-Multiplying Advanced Decision)
The Punch and Power amplifiers use an
analog computer process
to
maximize safe output power under all operating conditions. Rock-
ford Fosgate pioneered and developed
RTP
(Real Time Protection),
a crucial element in the performance edge of our amplifiers. The
innovative
NOMAD
(NOn-Multiplying Advanced Decision) system
is the most sophisticated version of this technique ever used,
bringing previously unavailable levels of accuracy, stability, tem-
perature immunity and reliability to this critical process. NOMAD
makes advanced decisions based on device voltages to precisely
control the awesome levels of current available in the output
MOSFETs to safe values – but only when absolutely needed.
THE RESULT: Extremely fast protection system that always protects
the amplifier and never degrades the sound.
◆ MOSFET Devices
Rockford Fosgate is one of the few manufacturers in the sound
community to utilize MOSFET devices in both the
power supply
and the
output stages
.
MOSFET
(Metal Oxide Semiconductor
Field Effect Transistor) devices offer several important inherent
advantages over the 30 year old technology of bi-polar design.
These advantages include: thermal stability, switching speed,
ultra low output impedance and wider bandwidth linearity. In
addition, MOSFETs operate very similar to vacuum tubes in
which they are more linear than bipolar transistors. However,
MOSFETs can deliver the midrange clarity without the limitations
of transient response and high frequency phase shifting normally
associated with tube operation.
THE RESULT: Operational characteristics similar to vacuum
tubes without the performance limitations of tube designs.
