Another View of TIMAudio This article was published in Audio magazine in February, 1980 at the height of the controversy surrounding Transient Intermodulation Distortion and its relationship with negative feedback. The article discusses the origins of TIM and the transient nature of music that can bring it on. It points out that amplifiers with inadequate slew rate margin are the ones prone to TIM. Moreover, the article demonstrates that large amounts of negative feedback, when properly applied, do not in any way contribute to TIM. The bad rap that negative feedback gets to this day is largely a result of that misconception. |
