◆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.
