◆ DSM
(Discrete Surface Mount) Technology
The DSM (Discrete Surface Mount) manufacturing process combines
the advantages of both discrete components and integrated circuitry.
Rockford Fosgate is the only American amplifier manufacturer to have
invested millions into this process. DSM components differ from
conventional discrete components in different ways. They are more
compact, more rugged, and they efficiently dissipate generated heat.
Using them wherever appropriate allows the advantages associated
with discrete circuitry to be retained while also providing room for
both highly advanced processing features and generous PC board
copper paths where needed. Their short lead-out structures allow
maximum audio performance and highest signal-to-noise ratios to be
obtained in amplifiers of desirable package size without resorting to
“amplifier-on-a-chip” shortcuts. These advantages are shown below
in Figure 1.

THE RESULT: Fewer connections, improved reliability, shorter signal
paths, superior signal-to-noise ratio and awesome sonic performance.

◆ NOMAD
(NOn-Multiplying Advanced Decision)
All Rockford Fosgate 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.
