TECHNICAL DESIGN FEATURES
◆TOPAZ (Tracking Operation Pre-Amplifier Zone)
The TOPAZ (Tracking Operation Pre-Amplifier Zone) circuitry solves ground loop noise problems common to automotive amplifier design. This innovative new development allows vastly improved isolation of the input signal grounds from the power supply ground of the amplifier. This is accomplished by allowing the source unit to control the potential “environment” of the entire input structure or “zone” of the amplifier. This process improves the noise rejection of the amplifier by 30-40dB – an astounding 30-100 times better than amplifiers without TOPAZ.
THE RESULT: Elimination of troublesome ground loop noise between source and amplifier.
◆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. Rockford Fosgate pioneered and developed RTP (Real Time Protection), a crucial element in the performance edge of our amplifiers. The innovative NOMAD (NOn-Multiply- ing Advanced Decision) system is the most sophisticated version of this technique ever used, bringing previously unavailable levels of accuracy, stability, temperature immunity and reliabil- ity 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.
