Amplifier Specs


Hey Guys:

Why would a company like B&K provide amplifier specs that use "cheater" measurments like "150 watts @ 1 kHz into 8 ohms"? I know the simple answer would be that their amplifiers can't deliver legitimate power and they need to "cheat" to get the specs up. But would a company like B&K, not exactly low end, really need to cheat?

Here is a link to the revised FTC regulation which "exempts 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."

It is actually 16CFR432 (Title 16, Part 432 of the Code of Federal Regulations), not 46CFR432 as referred to in the CEA document I linked to in my preceding post. The effectivity date is indicated as 60 days following publication in the Federal Register, which apparently was 12/22/2000 as indicated at the end of this text of the regulation.

BTW, the CEA was at that time a sector of the EIA, so Bob's comment was essentially correct.
