DSM

    DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

DSM - An industry-leading manufacturing process, DSM utilizes high-speed robotics, high-quality 1% tight-tolerance parts and large board traces. The discrete components are laser etched to meet a particular value and a very low tolerance. This lower tolerance improves the efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. These superior components are used by aerospace, automotive, and cellular manufacturers.

MEHSA³

    MEHSA³ reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

MEHSA³ (Maximum Efficiency Heat Sink Application - gen. 3) is a proprietary process that yields up to five times better heat transfer than traditional FET mounting techniques, using the exact same components. A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward & outward to quickly dissipate heat from each device across the heatsink. This process combined with our optimized heatsink designs, DSM (Discrete Surface Mount) technology and MOSFET devices, allows Rockford Fosgate to squeeze more watts per cubic inch from every output device as well as provide consistent thermal stability. The 3rd generation creates a dielectric layer between the ceramic topside and the aluminum base that retains all of the electrical isolation and capacitive coupling of the original MEHSA material increasing it's thermal conductivity. The higher power handling results in a 20% reduction in thermal impedance.

NOMAD

    NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.

This circuitry deals with the output stage protection in a Rockford Fosgate amplifier. You see, we at Rockford Fosgate think a good protection circuit is one that keeps your amp from going up in flames when the speaker wires touch together at full power, but won't shut down if the impedance of the load happens to dive when you are hammering your woofers.

The NOMAD circuit accomplishes just that. It's a totally new and very high tech method of dealing with device current and voltage parameters, without being affected by other factors such as heat. Our approach to "real time" protection is one that uses a mathematical transformation which eliminates the problems encountered with trying to do real time multiplication of instantaneous device voltage and current.

Essentially an analog computer calculates at each instant, the maximum allowable level of safe current for each output device, based on their instantaneous voltage drop. This allows the protection to be much more precise than ever before, and ensures reliability.
