Sec. 432.2  Required disclosures.

    (a) Whenever any direct or indirect representation is made of the 
power output, power band or power frequency response, or distortion 
characteristics of sound power amplification equipment, the following 
disclosure shall be made clearly, conspicuously, and more prominently 
than any other representations or disclosures permitted under this part: 
The manufacturer's rated minimum sine wave continuous average power 
output, in watts, per channel (if the equipment is designed to amplify 
two or more channels simultaneously) at an impedance of 8 ohms, or, if 
the amplifier is not designed for an 8-ohm impedance, at the impedance 
for which the amplifier is primarily designed, measured with all 
associated channels fully driven to rated per channel power. Provided, 
however, when measuring maximum per channel output of self-powered 
combination speaker systems that employ two or more amplifiers dedicated 
to different portions of the audio frequency spectrum, such as those 
incorporated into combination subwoofer-satellite speaker systems, only 
those channels dedicated to the same audio frequency spectrum should be 
considered associated channels that need be fully driven simultaneously 
to rated per channel power.
    (b) In addition, whenever any direct or indirect representation is 
made of the power output, power band or power

frequency response, or distortion characteristics of sound power 
amplification equipment in any product brochure or manufacturer 
specification sheet, the following disclosures also shall be made 
clearly, conspicuously, and more prominently than any other 
representations or disclosures permitted under this part:
    (1) The manufacturer's rated power band or power frequency response, 
in Hertz (Hz), for the rated power output required to be disclosed in 
paragraph (a) of this section; and
    (2) The manufacturer's rated percentage of maximum total harmonic 
distortion at any power level from 250 mW to the rated power output, and 
its corresponding rated power band or power frequency response.
