Rockford Fosgate R2-500X4 Prime 500W 4-Channel Amplifier

Primed for Performance, the R2-500X4 is a 500 watt, full-range Class-D amplifier capable of operating at 4Ω or 2Ω stereo and 4Ω bridged/mono. This amplifier is extremely efficient because of its Class-D technology which reduces demand on the vehicles electrical system. The amp also features C.L.E.A.N. circuitry to help you adjust your gain settings, a P.O.W.E.R. supply that generates more power as voltage increases.

R2 Amplifier Product Overview

Rockford Fosgate's R2 amplifiers are the building blocks for great audio systems, powerful enough to even DRIVE our Punch speakers and subwoofers. They have undergone an amazing upgrade by packing them with the latest features at an incredible value. Best of all, they are designed and engineered here in Tempe, Arizona.

Technologies:

CTA-2006 Compliant

Power ratings on Rockford Fosgate amplifiers conform to CTA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.

Full Range Class-D

A full-range version of the Class-D topology which is a high efficiency amplifier design that reduces current consumption from the charging system.

P.O.W.E.R.

Power supply circuit design that allows the amplifier to increase output power as voltage increases.

C.L.E.A.N. Set-Up

C.L.E.A.N. (Calibrated Level Eliminates Audible Noise) is a patented circuit with in/out clip LEDs to help match a source to amp and optimize output.

Balanced Differential Inputs

Differential inputs eliminate noise picked up by signal cables.

MEHSA 4 (Maximum Efficiency Heat Sink Application)

4(Maximum Efficiency Heat Sink Application - gen. 4) is a proprietary process that yields a better heat transfer than traditional FET mounting techniques, using the exact same components. An 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 4th generation is a ceramic isolator and provides improved EMI and advanced thermal coupling. The higher power handling results in a high reduction in thermal impedance.

MEHSA4reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

NOMAD

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.

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

Rollback Protection

During demanding musical conditions, the amplifier can dynamically reduce demand to prevent stress on the output devices.

CE Compliant

It proves to the authorities, but also to the buyer -or user- that this product fulfills all essential safety and environmental requirements as they are defined in the so-called European Directives.

The ce marking directive (93/68/EEC) was adopted on 07-22-1993 and updated as 768/2008 EC on 13-8-2008.

The directive gives a detailed description of the initials CE and any other marks specific to a particular directive and the many ways conformity may be acquired.

In return for fulfilling the CE marking requirements, the manufacturer or its agent gets the permission to cover the entire European market using only one approval procedure for the topics covered in the applicable directives.

No member state of the European Community can refuse trade of any (electronic or electrical) product that has been CE marked (unless fraud suspected). For some products however, national regulations exist, as long as the requirements covered in these national regulations are not covered by a pan-European Directive.

This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).
