What are sags and brownouts?

by ct_acoustic_frontier July 06, 2022

We've probably all experienced the momentary 'flickering' of lights when a heavy load such as a vacuum cleaner or amplifier is switched on within our home or studio. The flicker is a result of a short term 'sag' in the powerline voltage. Short duration sags, say between 20 and 40 thousandths of a second often cause no issues as most power supplies have enough stored energy to carry through these events. Longer sags will often result in loss of power, similar to an interruption. Brownouts are longer events, most typically caused by the power utility 'stretching' the power they have available to meet times of high demand. Linear power supplies, the type most often found in our high performance audio visual systems, are quite susceptible to prolonged low voltage. Power supplies may lose their ability to regulate voltage, causing equipment malfunction and damage. Amplifiers, which typically have unregulated power supplies, will show reduced ability to drive loudspeakers.  /><img class=

Room Correction: A Primer

Much confusion still exists about what a room correction product does, what problems it can (and cannot) solve and therefore its 'place' in a modern high quality sound reproduction system. Part of the challenge of understanding room correction is that it requires a reasonable level of understanding of sound quality, acoustic science, acoustic measurement and psychoacoustics (how humans perceive sound). The majority of the articles I have read online or in print magazines do not cover the fundamentals in enough depth to allow the curious and committed reader a chance to understand room correction on anything more than a cursory level. By the end of this article I hope that you will have learnt enough to judge for yourself what room correction can and cannot do and how best to apply it in the context of a world class music or home theater system.
