CEA-2006 Compliant
Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.
Read CEA-2006 Amplifier Power Standards under Answer ID #199 in our Knowledge Base.
An amplifier topology with the best of both worlds; a Class A preamp and Class B output stage.
Class A topologies area great for sound quality but can require alot of current. Class B designs are great for power delivery. Amplifier designs utilizing a Class A/B topology reaps the benefit of great sound quality in the front-end (preamplifier stage) while delivering great power in the output stages (MOSFET drivers).
CE Compliant
This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).
The ce mark is the official marking required by the European Community for all Electrical and Electronic equipment (and others) that will be sold, or put into service for the first time, anywhere in the European community.
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.
