The Federal Register Notice concerning the proposed amendments to the FTC Rule has finally been published:Status update??? Inquiring minds want to know, instead of getting more meaningful work done
Federal Register :: Request Access
The main issue with the stereo testing requirements will be the <.1% limit on THD. As excepted, the FTC is still punting on specific proposals for testing multichannel amps. The Notice reports some of the suggestions made in the last comment period, and then states that the authors presented no evidence that the proposed testing requirements represent common consumer usage (e.g., specifying that the surround channels should be run simultaneously at some reduced percentage of rated power for the mains, or that all channels should be run at full rated power simultaneously.) So the ball hasn't been advanced on the most critical issue. Public comments are due by September 26.
