Brand: QED
The acronym QED stands for "quod erat demonstrandum," which is Latin for "that which was to be shown." In scientific literature, it is often used at the end of a mathematical proof to indicate that all necessary steps have been taken to arrive at a logical conclusion. The A230 likely refers to a specific model or product from a company called QED, which is a manufacturer of audio and home theater equipment. However, without further context, it is unclear what exact product the A230 is.
