FEDERAL TRADE COMMISSION 

16 CFR Part 432 

Trade Regulation Rule Relating to 

Power Output Claims for Amplifiers 

Utilized in Home Entertainment 

Products 

AGENCY: Federal Trade Commission. 

ACTION: Supplemental notice of 

proposed rulemaking: Termination of 

rulemaking. 

SUMMARY: The Federal Trade 

Commission (‘‘FTC’’ or ‘‘Commission’’) 

has completed its review, pursuant to a 

supplemental notice of proposed 

rulemaking (‘‘SNPR’’), of the testing 

procedures for multichannel ‘‘home 

theater’’ amplifiers under the Trade 

Regulation Rule Relating to Power 

Output Claims for Amplifiers Utilized 

in Home Entertainment Products 

(‘‘Rule’’ or ‘‘Amplifier Rule’’). The 

Commission has determined not to 

amend the Rule at this time and to place 

the Rule on its regular review schedule 

for 2008 as part of the Commission’s 

ongoing systematic review of Federal 

Trade Commission rules and guides. 

Until the Commission provides further 

guidance regarding which channels 

need be associated for purposes of rating 

multichannel amplifiers, the 

Commission will not enforce the 

association requirement of Section 432.2 

of the Rule as it relates to the 

continuous power output per channel 

ratings for multichannel amplifiers. The 

Commission, however, will continue to 

enforce the other provisions of the Rule 

with regard to multichannel amplifiers. 

DATES: This rulemaking is terminated as 

of March 20, 2007. 

ADDRESSES: Requests for copies of this 

notice should be sent to the Consumer 

Response Center, Room 130, Federal 

Trade Commission, 600 Pennsylvania 

Ave., NW., Washington, DC 20580. The 

notice also is available on the Internet

SUPPLEMENTARY INFORMATION: 

I. Background 

The Amplifier Rule, promulgated in 

1974, assists consumers in purchasing 

power amplification equipment for 

home entertainment purposes by 

standardizing the measurement and 

disclosure of various performance 

characteristics. The Commission issued 

the Rule in response to sellers making 

misleading or confusing power 

distortion and other performance claims 

based on differing or unrecognized test 

procedures. The Rule establishes 

uniform test standards and disclosures 

so that consumers can make more 

meaningful comparisons of amplifier 

performance attributes. 

The present regulatory review began 

on April 7, 1997 (62 FR 16500). On July 

9, 1998, the Commission decided to 

retain the Rule, concluding that it 

continued to be valuable both to 

consumers and businesses (63 FR 

37234). At the same time, the 

Commission issued an advance notice of 

proposed rulemaking seeking comment 

on whether the Commission should 

initiate a rulemaking proceeding to 

address several technological and 

marketplace changes raised by industry 

(63 FR 37238). 

On December 22, 2000, the 

Commission amended the Rule to 

clarify the testing procedure for selfpowered speakers and eliminate or 

modify certain testing and disclosure 

requirements that had outlived their 

usefulness. At the same time, the 

Commission issued a SNPR soliciting 

comment on Commission proposals to 

amend the definition of ‘‘associated 

channels’’ in connection with the power 

rating testing of multichannel ‘‘home 

theater’’ amplifiers. Multichannel 

amplifiers incorporate five or more 

discrete or synthesized amplification 

channels and are designed to decode 

and/or amplify digitally encoded 

multichannel movie soundtracks or 

music program material recorded in 

various formats, including videocassette 

tapes or digital video discs (65 FR 

80798). Section 432.2(a) of the Rule 

requires that an amplifier’s continuous 

power output per channel be 

‘‘[m]easured with all associated 

channels fully driven to rated per 

channel power.’’ 1 Thus, manufacturers 

of multichannel audio/video receivers 

and amplifiers must decide which of the 

five or more discrete channels of 

amplification are considered 

‘‘associated’’ and, therefore, subject to 

simultaneous operation at full rated 

power. In the SNPR, the Commission 

solicited public comment on three 

alternative designations of ‘‘associated 

channels’’ for such audio amplifiers. 

The SNPR elicited one comment, 

submitted by the Consumer Electronics 

Association (‘‘CEA’’). CEA noted that 

there was no industry consensus on 

testing, measuring, and specifying the 

power output of multichannel amplifier 

products. Consequently, CEA formed an 

industry working group to establish a 

voluntary industry standard. 

On January 15, 2002, the Commission 

deferred action on the proposed rule but 

kept the rulemaking record open to 

allow time for a self-regulatory approach 

to develop a consensus procedure for 

the testing of multichannel amplifiers 

(67 FR 1915). Although CEA issued a 

standard, designated CEA–490–A, the 

Commission’s review has not found 

widespread adoption of this standard in 

advertisements or product 

specifications, and the Commission is
