What size power conditioner do I need?

by ct_acoustic_frontier July 06, 2022

To size a power conditioner note the following: UPS systems are sized according to the maximum amount of power, measured in Watts (W), that they can support. All other power conditioners are sized according to the maximum continuous amount of current, measured in Amps (A), that they can supply. The simplest way to determine the above is to purchase a Kill A Watt EZ Electricity Usage Monitor meter and plug all of the equipment into that. The Kill-A-Watt gives you both Watts and Amps. With equipment that consumes power dynamically such as audio gear you need to play a test signal such as pink noise through the system at the maximum volume you might listen to. This is because the power draw will be greater with a signal playing than without. If you don't have or don't want to buy a Kill-A-Watt then you will need to look at the manuals for your equipment and add up all of the power ratings. Once you have these you can divide by 120 to get the current draw in Amps. For example a simple system with a CD player (40W) and integrated amplifier (maximum 560W) would consume 600W or 5A.

Room Correction: A Primer

by Nyal Mellor July 28, 2022 0 Comments

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.
