◆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 similarly to vacuum tubes in that they are more linear than
THE RESULT: Operational characteristics similar to vacuum tubes without the performance limitations of tube design.
◆NOMAD (NOn-Multiplying Advanced Decision)
The Punch amplifiers use an analog computer process to maximize safe output power under all operating conditions. 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, temperature 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.
◆Punch EQ
The Punch EQ helps correct for acoustical deficiencies in the listening environment. Two unique potentiometers that control bass and treble compensate for the response errors present in most car environments. Unlike conventional tone controls, Punch EQ corrects the specific problems of poor low bass response and high frequency rolloff.
THE RESULT: Full range sound without excessive boost in areas where it is not needed.
