    ACTION: Advance Notice of Proposed Rulemaking.
    
    -----------------------------------------------------------------------
    
    SUMMARY: The Federal Trade Commission (``Commission'' or ``FTC''), has 
    completed its regulatory review of the Rule relating to Power Output 
    Claims for Amplifiers Utilized in Home Entertainment Products (the 
    ``Amplifier Rule'' or the ``Rule''). Pursuant to that review, the 
    Commission concludes that the Amplifier Rule continues to provide 
    benefits to consumers and firms. The regulatory review record also 
    suggests that certain substantive amendments to the Rule may be 
    appropriate, and could reduce compliance obligations without lessening 
    the protection provided by the Rule. Accordingly, the Commission seeks 
    comment on whether it should initiate a rulemaking proceeding to amend 
    the Rule to: reduce the preconditioning power output requirement from 
    one-third of rated power to a lower figure, such as one-eighth of rated 
    power; exempt sellers who make power output claims in media advertising 
    from the requirement to disclose total rated harmonic distortion and 
    the associated power bandwidth and impedance ratings; and clarify the 
    manner in which the Rule's testing procedures apply to self-powered 
    subwoofer-satellite combination speaker systems. The regulatory review 
    record also suggests that a non-substantive technical amendment be made 
    to the Rule to clarify the Rule's applicability to self-powered 
    loudspeakers for use in the home. A Notice of Final Action announcing 
    such amendment is published elsewhere in this Federal Register.
    
    DATES: Written comments will be accepted until September 8, 1998.
    
    ADDRESSES: Comments should be directed to: Secretary, Federal Trade 
    Commission, Room H-159, Sixth and Pennsylvania Ave., NW., Washington, 
    DC 20580. Comments about the Amplifier Rule should be identified ``16 
    CFR Part 432--Comment.''

    SUPPLEMENTARY INFORMATION:
    
    Part A--General Background Information
    
        The Commission is publishing this notice pursuant to Section 18 of 
    the FTC Act, 15 U.S.C. 57a et seq., the provisions of Part 1, Subpart B 
    of the Commission's Rules of Practice, 16 CFR 1.7, and 5 U.S.C. 551 et 
    seq. This authority permits the Commission to promulgate, modify, and 
    repeal trade regulation rules that define with specificity acts or 
    practices that are unfair or deceptive in or affecting commerce within 
    the meaning of Section 5(a)(1) of the FTC Act, 15 U.S.C. 45(a)(1).
        The Amplifier Rule was promulgated on May 3, 1974 (39 FR 15387), to 
    assist consumers in purchasing power amplification equipment for home 
    entertainment purposes by standardizing the measurement and disclosure 
    of various performance characteristics of the equipment. On April 7, 
    1997, the Commission published a Federal Register Notice (``FRN'') 
    seeking comment on the Rule as part of an ongoing project to review all 
    Commission rules and guides to determine their current effectiveness 
    and impact (62 FR 16500). This FRN sought comment on the costs and 
    benefits of the Rule, what changes in the Rule would increase its 
    benefits to purchasers and how those changes would affect compliance 
    costs, and whether technological or marketplace changes have affected 
    the Rule. The FRN also sought comment on issues related to the Rule's 
    product coverage, test procedures, and disclosure requirements.
        The FRN elicited six written comments.\1\ Two commenters expressed 
    continuing support for the Rule because it has given consumers a 
    standardized method of comparing the power output of audio 
    amplifiers.\2\ One commenter noted that industry use of this 
    standardized testing method has created a level playing field among 
    competitors.\3\ Another commenter stated that the rule may initially 
    have caused an increase in product prices, but ultimately manufacturers 
    have responded by making better products at more affordable prices.\4\ 
    None of the four remaining commenters stated that the costs of the Rule 
    exceeded its benefits, or that there were any other reasons why the 
    Rule should be rescinded. On the basis of this review, the Commission 
    has decided that the Rule provides benefits to consumers and industry 
    and that there is a continuing need for the Rule.

        The record also suggests that there have been technological and 
    marketplace changes that may warrant modifications to the Rule. 
    Accordingly, the Commission is publishing this ANPR seeking public 
    comment on whether it should initiate a rulemaking by publishing a 
    notice of proposed rulemaking (``NPR'') under section 18 of the FTC 
    Act, 15 U.S.C. 57a. The proceeding would address whether the Commission 
    should (1) Amend certain required test procedures that may impose 
    unnecessary costs on manufacturers; (2) eliminate certain disclosure 
    requirements in media advertising; and (3) clarify testing procedures 
    for self-powered speakers.
    
    Part B--Objectives the Commission Seeks To Achieve and Possible 
    Regulatory Alternatives
    
    1. Modifications to the Amplifier Rule Preconditioning Requirements
    
    a. Background
        Section 432.3(c) of the Rule specifies that an amplifier must be 
    preconditioned by simultaneously operating all channels at one-third of 
    rated power output for one hour using a sinusoidal wave at a frequency 
    of 1,000 Hz. The prior FRN questioned whether this preconditioning 
    requirement should be modified. One comment stated that the Rule's 
    preconditioning requirements do not reflect normal use conditions in 
    the home and are leading some manufacturers to design amplifiers with 
    excessively large and costly heat sinks, or to publish overly 
    conservative power ratings.\5\ Specifically, the commenter maintained 
    that operating a typical amplifier at one-third of rated power for an 
    hour represents a worst-case condition in terms of heat dissipation--
    one that exceeds the thermal stress that would be placed on the 
    amplifier when operating at full rated power. The
    
    [[Page 37239]]
    
    commenter states that Sec. 432.3(c) is particularly burdensome for high 
    power solid-state amplifiers during performance tests into 4 ohm loads. 
    The commenter maintained that, as a result, many manufacturers must 
    either refrain from publishing 4-ohm power specifications, publish 4-
    ohm power specifications that are lower than those the consumer could 
    achieve in typical home use, or provide otherwise unnecessary heat sink 
    capacity sufficient to protect the amplifier during preconditioning for 
    ratings at higher and more realistic power output levels.\6\ The 
    commenter also noted that existing industry standard test methods, such 
    as UL (Underwriters Laboratories) Standards 1492 and 6500, specify that 
    amplifiers be preconditioned at one-eighth of rated power.\7\

        \6\ Id. at 4-5.
        \7\ Id. at 4.
    ---------------------------------------------------------------------------
    
    b. Objectives and Regulatory Alternatives
        The record suggests that Sec. 432.3(c) should be amended to reflect 
    more realistically the maximum thermal stress that amplifiers are 
    likely to encounter during actual in-home use. Accordingly, the 
    Commission seeks comment on whether the Commission should amend the 
    rule to reduce the preconditioning power output requirement from one-
    third of rated power to a lower figure, such as one-eighth of rated 
    power.
    
    2. Amendment to Required Disclosures Section of the Amplifier Rule
    
    a. Background
        Section 432.2 of the Rule requires disclosure of maximum harmonic 
    distortion, power bandwidth, and impedance whenever a power claim is 
    made in any advertising, including advertising by retail stores, direct 
    mail merchants, and manufacturers. In the FRN, the Commission solicited 
    comment on whether there was a continuing need for the Rule to require 
    disclosure of maximum harmonic distortion in media advertising, or 
    whether such disclosure would be required only when maximum rated 
    harmonic distortion exceeds a specified threshold level, such as one 
    percent. In addition, the Commission solicited comment on whether 
    certain types of advertising, such as that commonly used by retail 
    stores to present basic price and feature information in a limited 
    amount of space, should be exempted from some or all of the power 
    bandwidth, distortion, and impedance disclosures.
        The one comment that addressed this issue stated that total 
    harmonic distortion below one percent has little meaning to consumers 
    because it is inaudible, and it recommended that the Commission 
    consider an exemption from disclosure of maximum rated harmonic 
    distortion when rated distortion is at or below one percent.\8\
    ---------------------------------------------------------------------------
    
        \8\ID. at 6.
    ---------------------------------------------------------------------------
    
        The Commission's own review of published specifications for 
    currently marketed power amplification equipment for use in the home 
    indicates that total harmonic distortion ratings in excess of one 
    percent are very rare. The few exceptions are associated primarily with 
    expensive vacuum tube power amplifiers occupying a highly specialized 
    segment of the high fidelity market.\9\
    ---------------------------------------------------------------------------
    
        \9\ Commission staff consulted the October, 1997 issue of Audio 
    magazine to obtain the manufacturer's rating of total harmonic 
    distortion for all receivers and separate power amplifiers included 
    in the magazine's annual equipment directory. The published ratings 
    show no receivers with total harmonic distortion exceeding one 
    percent. Among separate power amplifiers, 11 models from 5 
    manufacturers, out of approximately 1000 models from nearly 200 
    manufacturers, carry total harmonic distortion ratings exceeding one 
    percent. These 11 models range in price from $550 to $12,345. The 
    average price of the 11 models is about $3,700.
    ---------------------------------------------------------------------------
    
    b. Objectives and Regulatory Alternatives
        It appears that improvements in amplifier technology since the 
    Rule's promulgation in 1974 have reduced the benefits to consumers of 
    disclosure in media advertising of total rated harmonic distortion. It 
    also appears that an insufficient number of consumers would understand 
    the meaning and significance of the remaining triggered disclosures 
    concerning power bandwidth and impedance to justify their publication 
    in media advertising. Accordingly, the Commission seeks comment on 
    whether the Commission should initiate a rulemaking to amend the Rule 
    to exempt media advertising, including advertising on the Internet, 
    from disclosure of total rated harmonic distortion and the associated 
    power bandwidth and impedance ratings when a power output claim is 
    made.\10\
    ---------------------------------------------------------------------------
    
        \10\The record indicates, however, that maximum harmonic 
    distortion ratings in excess of one percent are not sufficiently 
    prevalent that the use of this figure as a threshold to govern 
    disclosure requirements in media advertising would be meaningful. 
    Thus, the suggested amendment does not limit the exemption to a 
    maximum harmonic distortion rating of one percent or less, as 
    previously proposed.
    ---------------------------------------------------------------------------
    
        In order to ensure that consumers would not be misled by 
    noncomparable power output claims that were based on differing 
    impedance ratings, the exemption for media advertising would be 
    conditioned on the requirement that the primary power output 
    specification disclosed in any media advertising be the manufacturer's 
    rated minimum sine wave continuous average power output, per channel 
    (such as might be true for certain amplifiers used in self-powered 
    speaker systems), at an impedance of 8 ohms, or, if the amplifier is 
    not designed for an 8-ohm load impedance, at the impedance for which 
    the amplifier is primarily designed.
        All other power output claims currently subject to the Rule, 
    however, including those appearing in manufacturer specification sheets 
    that are either in print or reproduced on the Internet, would continue 
    to trigger the requirement that the seller provide the full complement 
    of disclosures concerning power bandwidth, maximum harmonic distortion, 
    and impedance, so that interested consumers could obtain this 
    information prior to purchase.
    
    3. Rule Coverage of Self-Powered Loudspeakers for Use in the Home
    
    a. Background
        When the FRN was published, the Rule did not specifically mention 
    self-powered speakers as an example of sound amplification equipment 
    manufactured or sold for home entertainment purposes. In the FRN, the 
    Commission solicited comment on its tentative conclusion that the Rule 
    covers: (A) self-powered speakers for use with (i) home computers, (ii) 
    home sound systems, (iii) home multimedia systems; and (B) other sound 
    power amplification equipment for home computers. The Commission also 
    solicited comment on additional issues related to coverage of self-
    powered speakers under the Rule, including whether the standard test 
    conditions set out in the Rule are appropriate for such equipment.
        In a Notice of Final Action published separately in this Federal 
    Register, the Commission discusses the comments relating to the 
    threshold question of Rule coverage of self-powered speakers, and 
    issues a non-substantive amendment clarifying that the Rule applies to 
    self-powered loudspeakers for use in the home.
        The Commission received two comments that addressed the additional 
    issue of whether or not the Rule's standard test conditions are 
    appropriate for self-powered speakers. The principal trade association 
    of the U.S. electronics industry (CEMA) supported applying the Rule to 
    self-powered speakers. CEMA recommended, however, that the
    
    [[Page 37240]]
    
    Rule be amended at a future date to incorporate a standard for 
    measuring the volume of sound that a powered speaker can deliver into 
    the listening environment, rather than the power that the amplifier can 
    deliver to the speaker. This commenter stated that a voluntary industry 
    standard for measuring the loudness of powered speakers was currently 
    under development and could be incorporated into the Rule.\11\
    ---------------------------------------------------------------------------
    
        \11\ CEMA, (5), p. 7.
    ---------------------------------------------------------------------------
    
        The second commenter (Labtec) expressed concern that the Rule's 
    current testing protocol is not compatible with combination speaker 
    systems consisting of two or more amplifiers. For this reason, the 
    commenter proposed that the Commission amend the Rule to specify a 
    separate testing protocol and disclosure format for three-piece 
    multimedia speaker systems comprised of a subwoofer and two or more 
    satellite speakers that are powered by separate amplifiers that share a 
    common power supply.\12\
    ---------------------------------------------------------------------------
    
        \12\ Labtec, (6), p. 4.
    ---------------------------------------------------------------------------
    
        According to this commenter, the subwoofer and satellite amplifiers 
    in such combination systems are usually of different wattage per 
    channel and are dedicated to different frequency bandwidths. The 
    commenter stated further that if the Rule were interpreted to mean that 
    power tests for these systems be conducted over the entire frequency 
    bandwidth from 20Hz to 20kHz, with all channels of all amplifiers 
    driven simultaneously, limitations in the common power supply would 
    lower the maximum power output of the subwoofer and satellite 
    amplifiers at test frequencies near the crossover frequency, where both 
    sets of amplifiers would be operating near full capacity.\13\
    ---------------------------------------------------------------------------
    
        \13\ Id.
    ---------------------------------------------------------------------------
    
        The commenter also stated that the most conservative industry 
    practice today is to measure the subwoofer and satellite amplifiers 
    separately, and to disclose the maximum per-channel continuous power 
    output of each amplifier over the bandwidth for which it was designed 
    to operate. In this test protocol, the commenter stated, the two 
    channels of the satellite amplifier are driven simultaneously, but 
    without the subwoofer amplifier in operation. Similarly, the test for 
    the subwoofer amplifier are conducted alone, with the satellite 
    amplifier at idle. These ratings are then disclosed in a format such 
    as: ``20 watts RMS subwoofer, 10 watts RMS satellite (5w + 5w).'' 
    According to the commenter, such power ratings overstate somewhat the 
    maximum per-channel power capability of each amplifier when all 
    channels of both amplifiers are driven simultaneously at the crossover 
    frequency.\14\
    ---------------------------------------------------------------------------
    
        \14\ Id. at 3.
    ---------------------------------------------------------------------------
    
        The commenter recommended that the Rule be amended to specify that 
    power rating tests for combination subwoofer-satellite power speaker 
    systems be conducted at the crossover frequency with all channels of 
    all amplifiers operating simultaneously. The comment also suggested 
    that manufacturers be allowed to publish the combined power output of 
    the subwoofer and satellite amplifiers at this frequency, together with 
    the individual per-channel output of each amplifier, e.g., ``25 watts 
    total RMS power (17w+4w+4w) into 4 ohms @ 150 Hz with less than 1% 
    THD.'' \15\
    ---------------------------------------------------------------------------
    
        \15\ Id. at 4.
    ---------------------------------------------------------------------------
    
    b. Objectives and Regulatory Alternatives
        As discussed in the Notice of Final Action published separately in 
    this Federal Register, the Commission has concluded that Rule coverage 
    of self-powered speaker equipment for use in the home should not be 
    delayed until an industry standard is developed for measuring and 
    disclosing the volume of sound that such speaker systems can produce in 
    the listening environment.
        The Commission has also tentatively determined on the basis of the 
    Rule review record that Sec. 432.2(a)(2) of the Rule does not currently 
    provide adequate guidance concerning the manner in which power ratings 
    for combination subwoofer and satellite self-powered speaker systems 
    should be conducted. Specifically, it may be insufficiently clear 
    whether the Rule's stipulation that power measurements be made ``with 
    all associated channels fully driven to rated per channel power'' 
    requires manufacturers to conduct power ratings with all channels of 
    both the subwoofer and satellite amplifiers driven simultaneously, or 
    whether the Rule allows manufacturers of such equipment to test the 
    subwoofer and satellite amplifiers separately.
        The Commission is not prepared at this time to recommend that the 
    Rule be amended to specify that per-channel power ratings for self-
    powered combination subwoofer and satellite speaker systems be 
    conducted at the crossover frequency with all channels of all 
    amplifiers operating simultaneously, as proposed by Labtec. The 
    Commission does not have sufficient evidence to conclude that in-home 
    use, under even strenuous conditions, typically would place maximum 
    continuous power demands simultaneously on both the subwoofer and 
    satellite amplifiers at the crossover frequency. Rather, such demands 
    are more likely to occur in portions of the audio spectrum that would 
    be assigned primarily either to the subwoofer amplifier or the 
    satellite amplifier.
        The Commission therefore believes that the most appropriate 
    application of the Rule to self-powered subwoofer-satellite 
    combinations would be to require simultaneous operation only of those 
    channels dedicated to the same portion of the audio frequency spectrum. 
    Accordingly, the Commission seeks comment on whether to initiate a 
    rulemaking proceeding to clarify the Amplifier Rule by amending 
    Sec. 432.2 to include a note stating that, for self-powered combination 
    speaker systems that employ two or more amplifiers dedicated to 
    different portions of the audio frequency spectrum, only those channels 
    dedicated to the same audio frequency spectrum need be fully driven to 
    rated per channel power under paragraph 432.2(a)(2).
    
    4. Rule Coverage of Automotive Sound Amplification Products
    
    a. Background
        The scope of the Amplifier Rule currently is limited to sound power 
    amplification equipment intended for home entertainment purposes. The 
    Rule does not apply to automotive sound amplification products. The 
    Commission noted that promotional materials for these products appear 
    to contain power output claims based on a variety of rating procedures. 
    The Commission requested comment on the types of power rating and 
    disclosure protocols currently used by manufacturers of automotive 
    sound amplification products, and whether any of the sound power claims 
    being made in connection with the sale and advertising of such 
    equipment inhibit meaningful comparisons of performance attributes by 
    consumers. The Commission also solicited examples of such claims and 
    information establishing the scope and seriousness of the problem. 
    Finally, the Commission asked for comment on what, if any, form of 
    action was needed to increase the ability of consumers to make 
    meaningful product comparisons in this industry.
        The Commission received three comments on these issues. The 
    commenters stated that power claims made for automotive sound 
    amplification equipment frequently are higher than the corresponding 
    RMS continuous power rating specified in the
    
    [[Page 37241]]
    
    Rule. The commenters recommended that the Rule be extended to cover 
    automotive sound amplification equipment.\16\ None of the commenters, 
    however, provided any specific examples of claims that might mislead 
    consumers and lead to poor purchase decisions. Nor was any information 
    provided on the prevalence or technical basis for claims that differ 
    from the corresponding continuous power output rating used in the Rule. 
    Finally, no evidence was provided indicating that the various power 
    ratings currently in use are inhibiting meaningful comparisons by 
    consumers.
    ---------------------------------------------------------------------------
    
        \16\ See Fulmer, (2), p. 1; Phillips, (1), p. 1; CEMA, (5), p. 
    9.
    ---------------------------------------------------------------------------
    
        Commission staff, prior to the issuance of the FRN, conducted a 
    brief examination of current power output claims for automotive stereo 
    equipment.\17\ This examination suggests that manufacturers of original 
    equipment and aftermarket dashboard radio-cassette or radio-CD players 
    generally employ a rating system that yields a ``peak'' power output 
    specification approximately twice as high as the continuous rating. 
    Staff found no evidence, however, that this rating system misrepresents 
    the relative power output of competing amplifiers, or that any 
    confusion resulting from the system has led to a breakdown in the 
    correspondence between the prices charged for competing amplifiers and 
    their power output capabilities. Staff's inquiry also indicates that 
    the FTC continuous rating protocol is the most common method of 
    measuring the power output of specialized and generally more expensive 
    aftermarket automotive sound reproduction equipment, such as separate 
    power amplifiers and powered subwoofers.
    ---------------------------------------------------------------------------
    
        \17\ Staff's inquiry included visits to several area auto stereo 
    dealers, an inspection of retailer ads in the Washington Post, and 
    an analysis of power output specifications published in recent 
    catalogues for Crutchfield, a large mail-order retailer of auto 
    stereo equipment.
    ---------------------------------------------------------------------------
    
    b. Objectives and Regulatory Alternatives
        The Rule review record suggests that certain power output ratings 
    for automotive sound amplification equipment may differ from the 
    ratings that would be obtained using a continuous power testing 
    procedure similar to that specified in the Rule. As indicated, the 
    record contains no evidence regarding whether such power output claims 
    could impede the ability of consumers to make meaningful comparisons, 
    or that the various ratings systems currently in use have significantly 
    reduced the correspondence between the prices charged for competing 
    auto sound amplification equipment and the power output of this 
    equipment. In addition, staff's inquiry did not indicate that consumers 
    may currently pay more for amplification equipment that is actually 
    less powerful, or no more powerful, than competing equipment advertised 
    with power disclosures that are derived using more rigorous test 
    procedures. Thus, the record and Commission staff's inquiry uncovered 
    no basis for concluding that consumers currently are unable to make 
    meaningful comparisons in the automotive sound reproduction market. The 
    Commission has concluded, therefore, that the existence of dissimilar 
    power output rating methods by itself does not provide a sufficient 
    showing of probable consumer injury to justify again seeking comment on 
    this issue in this APNR.

        Members of the public are invited to comment on any issues or 
    concerns they believe are relevant or appropriate to the Commission's 
    consideration of whether to publish an NPR initiating a rulemaking 
    proceeding to consider the previously discussed proposed amendments to 
    the Amplifier Rule. The Commission requests that factual data upon 
    which the comments are based be submitted with the comments. In 
    addition to the issues raised above, the Commission solicits public 
    comment on the specific questions identified below. These questions are 
    designed to assist the public and should not be construed as a 
    limitation on the issues on which public comment may be submitted. 
    After considering the responses to this ANPR, if the Commission decides 
    to commence a rulemaking proceeding, it must, under the Regulatory 
    Flexibility Act, 5 U.S.C. 601-12, determine whether the proposed 
    amendments would have a significant impact on a substantial number of 
    small businesses. The Commission includes in this ANPR questions that 
    will assist it in making such analysis.
        The written comments submitted will be available for public 
    inspection in accordance with the Freedom of Information Act, 5 U.S.C. 
    552, and Commission regulations on normal business days from 8:30 a.m. 
    to 5:00 p.m. at the Federal Trade Commission, 6th St. and Pennsylvania 
    Ave., N.W., Room 130, Washington, D.C. 20580.
    
    Questions
    
    A. Section 432.3(c) Preconditioning Requirement
    
        (1) Should the Commission amend the Rule to reduce the 
    preconditioning power output requirement from one-third of rated power 
    to a lower figure, such as one-eighth of rated power?
    
    B. Exemption From Required Disclosures
    
        (2) Have post-1974 improvements in amplifier design and consequent 
    reductions in typical levels of total harmonic distortion reduced the 
    benefit to consumers of disclosure of rated total harmonic distortion 
    in media advertising that contains a power output claim?
        (3) Should the Commission amend the Rule to exempt disclosure of 
    total rated harmonic distortion and the associated power bandwidth and 
    impedance ratings when a power output claim is made in media 
    advertising?
        (4) If the Commission amends the rule to allow the above exemption, 
    should this exemption be conditioned on the requirement that the 
    primary power output specification disclosed in any media advertising 
    be the manufacturer's rated minimum sine wave continuous average power 
    output, per channel, at an impedance of 8 ohms, or, if the amplifier is 
    not designed primarily for an 8-ohm impedance, at the impedance for 
    which the amplifier is primarily designed?
    
    C. Rule Coverage of Self-Powered Loudspeakers for Use in the Home
    
        (5) Should the Commission clarify the Rule to specify that, for 
    self-powered combination speaker systems that employ two or more 
    amplifiers dedicated to different portions of the audio frequency 
    spectrum, only those channels dedicated to the same audio frequency 
    spectrum need be fully driven to rated per channel power under 
    Sec. 432.2(a)(2)? If not, should the Commission amend the Rule to 
    specify that per-channel power ratings for such combination speaker 
    systems be conducted at the crossover frequency with all channels of 
    all amplifiers operating simultaneously?
    
    D. Economic Effect, If Any, of the Proposed Amendments
    
        (6) What costs and benefits to consumers and businesses, including 
    manufacturers, retailers, or other sellers, would accrue from each of 
    the three proposed Rule amendments?
        (7) Would any of the proposed Rule amendments have a significant
    
    [[Page 37242]]
    
    economic impact on a substantial number of small businesses?
        (8) Can that impact be quantified?
