C'est pas CEA 2006??

CEA-2006 Compliant
On May 28, 2003, the Consumer Electronics Association published standard CEA-2006, "Testing & Measurement Methods for Mobile Audio Amplifiers." This "voluntary" standard advocates a uniform method for determining an amplifier's RMS power and signal-to-noise ratio. Using 14.4 volts, RMS watts are measured into a 4-ohm impedance load at 1 percent Total Harmonic Distortion (THD) plus noise, at a frequency range (for general purpose amplifiers) of 20 Hz to 20,000 Hz. Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. This applies to both external amplifiers and the amplifiers within in-dash receivers.  
 
CEA-2006 allows consumers to be able to compare car amplifiers and receivers on an equal basis. Manufacturers who choose to abide by the new standard are able to stamp their products with the CEA-2006 logo that reads: "Amplifier Power Standard CEA-2006 Compliant."

CEA Adopts Standard Rating System for Measuring the Performance of Mobile Audio Amplifiers
 
--------------------------------------------------------------------------------
Arlington, Virginia 6/26/2003
 
The Consumer Electronics Association (CEA) announced today that its Mobile Electronics Committee (R6) has adopted a standard rating system for measuring the performance of mobile audio amplifiers. The new standard, designated CEA-2006 - Testing and Measurement Methods for Mobile Audio Amplifiers, was created to make it easier for consumers to compare technical characteristics that determine the quality of mobile audio amplifiers. The standard applies to headunits, separate amplifiers and subwoofer amplifiers. Products that comply with CEA-2006 will be authorized to carry a corresponding logo.  
 
"This standard benefits retailers and consumers by providing a logical measurement tool that helps demystify audio," said Pat Lavelle, president and CEO of Audiovox and chairman of CEA's Mobile Electronics division. "The ratings and disclosures provide a consistent, technically reliable resource for consumers to use when making purchase decisions."  
 
"CEA-2006 fills the void that previously existed when consumers needed a uniform measurement method to compare different products," said Ralph Justus, vice president of technology and standards for CEA. "This standard helps clarify product differences, particularly regarding rated power output and distortion, and helps increase consumer confidence about their purchase by helping to educate consumers about the product's benefits."  
 
The primary measurement criteria outlined in CEA-2006 are power output, the signal-to-noise ratio and total harmonic distortion plus noise (THD+N). With the new standard, consumers should expect to see two primary ratings - an amplifier's primary power output in watts (RMS) and the signal-to-noise ratio in dBA. The primary power output in watts is measured at a level with less than one percent THD+N to indicate how much continuous power the amplifier delivers at that low distortion level. The signal-to-noise ratio is measured at a reference level of one watt. A larger signal-to-noise ratio number indicates more desirable audio and less noise in an amplifier's output.

CEA-2006, une certification pour les amplificateurs
26 septembre 2003
 
     
   
   
 
Le logo de la Consumer Electronics Association  
 
       
USA - Le CEA est une association américaine qui est destinée à promouvoir et à développer tout ce qui concerne l'électronique grand public, de l'audio portable au home cinema en passant par le car audio. Le CEA est également le promoteur du CES, le plus grand salon dédié à l'électronique grand public qui se déroule chaque année à Las Vegas. Le CEA développe aussi un grand nombre de recommandations et de certifications à l'attention des constructeurs et des consommateurs. Une nouvelle certification dans le domaine du car audio va être mise en place dès 2004 et elle concerne les amplificateurs. Tous les fabricants qui le désireront pourront bénéficier de la certification CEA-2006. Cette dernière a pour but de mesurer la puissance efficace et le taux de distorsion de tous les amplificateurs avec le même protocole. De cette manière, les consommateurs pourront enfin comparer les produits sur les mêmes bases. Les produits certifiés CEA-2006 recevront un logo spécifique et facilement reconnaissable. Tous les produits embarquant une section d'amplification pourront recevoir ce logo : amplificateurs séparés, caissons amplifiés, autoradios.
