Product Description

ROCKFORD FOSGATE - Punch PBR500X1

     The Punch PBR500X1 uses our patented BRT (Boosted Rail Technology) for an ultra efficient design that does not use a switching power supply to generate its rated power. This allows the chassis design to be much smaller than traditional sized amplifiers. The BRT also has a variable hi-level DC offset turn-on circuit for easy installation into any OEM system. It is great for smaller stealth installations, as well as for motorcycles and recreational vehicles.

 

     The PBR500X1 is a 500 Watt amplifier with Boosted Rail Technology, allowing it to be compact and efficient while providing big power. This amp is great for smaller stealth installations, motorcycles and recreational vehicles.

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.

 

 

 

Punch EQ2

 

U.S. Patent Patent Pending

Onboard equalizer with up to +18dB @ 45Hz and/or up to +12dB boost at 12kHz.

 

In the early 70's, Jim Fosgate studied the acoustical properties of automobiles. Utilizing a real-time analyzer and pink noise, he would graph out the acoustical characteristics of each car he tested. Jim discovered three problems that were common to all cars:

  • A midbass hump between 100-275Hz
  • A steep roll-off of high frequencies from 2kHz up to 20kHz
  • Reduced bass response below 50Hz

The Punch EQ on-board equalization circuit helps correct for these acoustical deficiencies in the listening environment. When set to Low-Pass(LP) operation, it becomes a variable Bass Boost. When set to High-Pass (HP) operation, it acts as a variable Mid-Bass and Treble Boost. When set to All Pass (AP) operation, both Bass and Treble frequencies are boosted.

 

 

 

 

 

DTM

 

    Dynamic Thermal Management evenly distributes excess heat across entire amplifier heatsink.

Heat is often inefficiently dissipated across a heatsink causing "hot spots". This impacts important design goals which are:



Rockford Fosgate engineers have developed an award winning cooling design called DTM. This patent pending design seamlessly manages the output of power supply temperatures, while evenly distributing the excess heat across the entire amplifier.

  • Keeping internal components cool.
  • Maximizing potential of all components.
  • Reducing distortion for better sound quality.
  • Increasing efficiency to produce more power.

 

 

 

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.
