    * = Channels are measured separately
    ** = Calculated on basis of IHF Dynamic headroom
    What is the Fedral Trade Commmision (FTC) Standard? Were last years Onkyo's rated using the same FTC standard?

    Carol; On and off on the HTF I believe this FTC question has been brought up in some way. Since I have been around awhile in the hobby of audio, back in the 60s and 70s, many audio manufacturers especially outfits like Zenith that made stereo consoles would brag about having 400 watts of power. Of course the ads would not really designate what measurement of power was being used. I believe for example that Lafayette Electronics used the IHF system, others used EIA, or IPP. The FTC finally "cracked down" on this whole business which may have been in 1974. I am looking right now at a DYNACO brochure of which ratings on their audio equipment were changed due to FTC requirements at that time and probably are still in force today. One of the requirements before rating products from the FTC was the PRECONDITIONING rule. Dynaco objected only to that part of the ruling. Their vacume tube equipment took a shellacing on the bandwith; for instance there famous Stereo 70 power amp rated at 30watts per channel now became 20 watts per channel in a badwith of 50-10,000HZ. Their solid state equipment dropped about 10 watts per channel but basically maintained their 20 to 20Khz bandwith at 8 ohms. Their distortion rates on their solid state equipment at rated power was .5% and .25%. I built and owned a Stereo 70. It was a beautiful sounding piece of equipment.
    Your interest on any receiver made today such as the Onkyos' is the rating given at 20-20KHZ @ 8ohms. The distortion bandwith factor is to be considered too. I believe the Onkyos' are .08 percent in each of their channels which I would consider quite a good specification these days. There are receivers out there FUDGING their specs at the 1000HZ level at 40-20KHz. Some of their distortion levels are as high as the OLD DAYS which is .7 percent. These units may still sound good and provide adequate power depending on the distortion created by the outside sources feeding the receivers. While the specs are important, your satisfaction with the sound quality, set-ups for its features and remote count towards ownership of a particular item.

    Thanks Gary. I was just wondering because a lot of talk on this forum has been about the "new" Onkyo watts compared to the "old" Onkyo watts. Believe it or not...my father still has an old Lafayette stereo receiver from the 60's that's in a guest bedroom & it's still working. As he says, "The thing just won't die" [​IMG]
