Amplifier Power for Mobile Electronics, CTA-2006-B

    Program Description

    The amplifier power for mobile electronics logo indicates that a car amplifier has been tested to CTA-2006-B, testing and measurement methods for mobile audio amplifiers. The standard requires that the manufacturers report at least three ratings: primary power output in watts, total harmonic distortion plus noise and signal to noise ratio.

    It's partner mark, the mobile loudspeaker logo, indicates that a car loudspeaker has been tested in accordance with CTA-2031, testing and measurement methods for mobile loudspeaker systems. CTA-2031 defines test procedures for rating the performance and physical size of mobile loudspeakers and requirements for reporting the performance.

    When consumers use the information found with both logos, they will be able to select mobile loudspeakers with power handling capabilities that are appropriate for the power output characteristics of their mobile amplifiers.
