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.
